Rejected because extension not found in context

Hello,

I have this in sip.conf:

[basic-options](!)                ; a template
        dtmfmode=rfc2833
        context=internal
        type=friend
	language=es
	host=dynamic

[natted-phone](!,basic-options)   ; another template inheriting basic-options
        nat=yes
        directmedia=no


[public-phone](!,basic-options)   ; another template inheriting basic-options
        nat=no
        directmedia=yes

[my-codecs](!)                    ; a template for my preferred codecs
        disallow=all
        allow=alaw
        allow=g729
        allow=gsm
        allow=g723


[ulaw-phone](!)                   ; and another one for ulaw-only
        disallow=all
        allow=ulaw

; and finally instantiate a few phones
;
 [2133](public-phone,my-codecs)
        secret = 2133
 [2134](public-phone,my-codecs)
        secret = 2134
 [2136](public-phone,my-codecs)
        secret = 2136

in extensions.conf i have this:[code]

[internal]
exten => _2XXX,1,Dial(SIP/${EXTEN},20,tT)
exten => _2XXX,2,Hangup()
include => parkedcalls
[/code]

The Extension 2133 is a Cisco SPA504G (Register Failed).
The Extension 2134 is my JavaSE Application (Register Successful).
The Extension 2136 is Peers Java SIP Client (Register Successful).

My problem, besides that Cisco SPA504G Resister is Failed, is that when I make a call I get the following warning in the CLI:

[May  3 16:27:47] NOTICE[2125]: chan_sip.c:21485 handle_request_invite: Call from '2136' to extension '2134' rejected because extension not found in context 'internal'.

Please, could someone help me.

Best regards
Javier

is the cisco phone local or remote?
You dont show the portion of sip.conf that relates to the sip phone???

Thanks riddlebox for your reply,

do not quite understand the question but this is how I have the SPA504:

A – Cisco SPA504
B – Asterisk 1.8
C – Huaweii Router

A and B are connected to C.

I guess it’s local

In sip.conf i have this for Cisco SPA:

[2133](public-phone,my-codecs) secret = 2133

Cisco phone show the extenion 2133 in display, but ne orange flashing lights would have to be green when it register the extension.

Sorry for my english.

Best regards

Looks like a bug…

  1. Try not to use templates within sip.conf
  2. Try to use 1.4.X branch with this config files

If somethig of this will help, go to bugtracker )

this same configuration worked fine in Asterisk 1.8.3.2

I’m installing that version to see if it works

Thank you

1.8.3.2 not work for me.

make uninstall && make uninstall-all

wget Asterisk 1.8.3.3 && ./configure && make menuselect && make && make install && make samples

This is my full extensions.conf:

[code]; extensions.conf - the Asterisk dial plan
;
; Static extension configuration file, used by
; the pbx_config module. This is where you configure all your
; inbound and outbound calls in Asterisk.
;
; This configuration file is reloaded
; - With the “dialplan reload” command in the CLI
; - With the “reload” command (that reloads everything) in the CLI

;
; The “General” category is for certain variables.
;
[general]
;
; If static is set to no, or omitted, then the pbx_config will rewrite
; this file when extensions are modified. Remember that all comments
; made in the file will be lost when that happens.
;
; XXX Not yet implemented XXX
;
static=yes
;
; if static=yes and writeprotect=no, you can save dialplan by
; CLI command “dialplan save” too
;
writeprotect=no
;
; If autofallthrough is set, then if an extension runs out of
; things to do, it will terminate the call with BUSY, CONGESTION
; or HANGUP depending on Asterisk’s best guess. This is the default.
;
; If autofallthrough is not set, then if an extension runs out of
; things to do, Asterisk will wait for a new extension to be dialed
; (this is the original behavior of Asterisk 1.0 and earlier).
;
;autofallthrough=no
;
;
;
; If extenpatternmatchnew is set (true, yes, etc), then a new algorithm that uses
; a Trie to find the best matching pattern is used. In dialplans
; with more than about 20-40 extensions in a single context, this
; new algorithm can provide a noticeable speedup.
; With 50 extensions, the speedup is 1.32x
; with 88 extensions, the speedup is 2.23x
; with 138 extensions, the speedup is 3.44x
; with 238 extensions, the speedup is 5.8x
; with 438 extensions, the speedup is 10.4x
; With 1000 extensions, the speedup is ~25x
; with 10,000 extensions, the speedup is 374x
; Basically, the new algorithm provides a flat response
; time, no matter the number of extensions.
;
; By default, the old pattern matcher is used.
;
; ****This is a new feature! *********************
; The new pattern matcher is for the brave, the bold, and
; the desperate. If you have large dialplans (more than about 50 extensions
; in a context), and/or high call volume, you might consider setting
; this value to “yes” !!
; Please, if you try this out, and are forced to return to the
; old pattern matcher, please report your reasons in a bug report
; on https://issues.asterisk.org. We have made good progress in providing
; something compatible with the old matcher; help us finish the job!
;
; This value can be switched at runtime using the cli command “dialplan set extenpatternmatchnew true”
; or “dialplan set extenpatternmatchnew false”, so you can experiment to your hearts content.
;
;extenpatternmatchnew=no
;
; If clearglobalvars is set, global variables will be cleared
; and reparsed on a dialplan reload, or Asterisk reload.
;
; If clearglobalvars is not set, then global variables will persist
; through reloads, and even if deleted from the extensions.conf or
; one of its included files, will remain set to the previous value.
;
; NOTE: A complication sets in, if you put your global variables into
; the AEL file, instead of the extensions.conf file. With clearglobalvars
; set, a “reload” will often leave the globals vars cleared, because it
; is not unusual to have extensions.conf (which will have no globals)
; load after the extensions.ael file (where the global vars are stored).
; So, with “reload” in this particular situation, first the AEL file will
; clear and then set all the global vars, then, later, when the extensions.conf
; file is loaded, the global vars are all cleared, and then not set, because
; they are not stored in the extensions.conf file.
;
clearglobalvars=no
;
; If priorityjumping is set to ‘yes’, then applications that support
; ‘jumping’ to a different priority based on the result of their operations
; will do so (this is backwards compatible behavior with pre-1.2 releases
; of Asterisk). Individual applications can also be requested to do this
; by passing a ‘j’ option in their arguments.
;
;priorityjumping=yes
;
; User context is where entries from users.conf are registered. The
; default value is ‘default’
;
;userscontext=default
;
; You can include other config files, use the #include command
; (without the ‘;’). Note that this is different from the “include” command
; that includes contexts within other contexts. The #include command works
; in all asterisk configuration files.
;#include “filename.conf”
;#include <filename.conf>
;#include filename.conf
;
; You can execute a program or script that produces config files, and they
; will be inserted where you insert the #exec command. The #exec command
; works on all asterisk configuration files. However, you will need to
; activate them within asterisk.conf with the “execincludes” option. They
; are otherwise considered a security risk.
;#exec /opt/bin/build-extra-contexts.sh
;#exec /opt/bin/build-extra-contexts.sh --foo=“bar”
;#exec </opt/bin/build-extra-contexts.sh --foo=“bar”>
;#exec “/opt/bin/build-extra-contexts.sh --foo=“bar””
;

; The “Globals” category contains global variables that can be referenced
; in the dialplan with the GLOBAL dialplan function:
; ${GLOBAL(VARIABLE)}
; ${${GLOBAL(VARIABLE)}} or ${text${GLOBAL(VARIABLE)}} or any hybrid
; Unix/Linux environmental variables can be reached with the ENV dialplan
; function: ${ENV(VARIABLE)}
;

;
; g: select the lowest-numbered non-busy DAHDI channel

; WARNING WARNING WARNING WARNING
; If you load any other extension configuration engine, such as pbx_ael.so,

; WARNING WARNING WARNING WARNING
;
; Any category other than “General” and “Globals” represent
; extension contexts, which are collections of extensions.
;
; Extension names may be numbers, letters, or combinations
; thereof. If an extension name is prefixed by a ‘_’
; character, it is interpreted as a pattern rather than a
; literal. In patterns, some characters have special meanings:
;
; X - any digit from 0-9
; Z - any digit from 1-9
; N - any digit from 2-9
; [1235-9] - any digit in the brackets (in this example, 1,2,3,5,6,7,8,9)
; . - wildcard, matches anything remaining (e.g. _9011. matches
; anything starting with 9011 excluding 9011 itself)
; ! - wildcard, causes the matching process to complete as soon as
; it can unambiguously determine that no other matches are possible
;
; For example, the extension _NXXXXXX would match normal 7 digit dialings,
; while _1NXXNXXXXXX would represent an area code plus phone number
; preceded by a one.
;
; Each step of an extension is ordered by priority, which must always start
; with 1 to be considered a valid extension. The priority “next” or “n” means
; the previous priority plus one, regardless of whether the previous priority
; was associated with the current extension or not. The priority “same” or “s”
; means the same as the previously specified priority, again regardless of
; whether the previous entry was for the same extension. Priorities may be
; immediately followed by a plus sign and another integer to add that amount
; (most useful with ‘s’ or ‘n’). Priorities may then also have an alias, or
; label, in parentheses after their name which can be used in goto situations.
;
; Contexts contain several lines, one for each step of each extension. One may
; include another context in the current one as well, optionally with a date
; and time. Included contexts are included in the order they are listed.
; Switches may also be included within a context. The order of matching within
; a context is always exact extensions, pattern match extensions, includes, and
; switches. Includes are always processed depth-first. So for example, if you
; would like a switch “A” to match before context “B”, simply put switch “A” in
; an included context “C”, where “C” is included in your original context
; before “B”.
;
;[context]
;exten => someexten,{priority|label{+|-}offset}[(alias)],application(arg1,arg2,…)
;
; Timing list for includes is
;
; ,,,[,]
;
; Note that ranges may be specified to wrap around the ends. Also, minutes are
; fine-grained only down to the closest even minute.

; ignorepat can be used to instruct drivers to not cancel dialtone upon receipt
; of a particular pattern. The most commonly used example is of course ‘9’
; like this:
;
;ignorepat => 9
;
; so that dialtone remains even after dialing a 9. Please note that ignorepat
; only works with channels which receive dialtone from the PBX, such as DAHDI,
; Phone, and VPB. Other channels, such as SIP and MGCP, which generate their
; own dialtone and converse with the PBX only after a number is complete, are
; generally unaffected by ignorepat (unless DISA or another method is used to
; generate a dialtone after answering the channel).

[code];
; SIP Configuration example for Asterisk
;
; Note: Please read the security documentation for Asterisk in order to
; understand the risks of installing Asterisk with the sample
; configuration. If your Asterisk is installed on a public
; IP address connected to the Internet, you will want to learn
; about the various security settings BEFORE you start
; Asterisk.
;
; Especially note the following settings:
; - allowguest (default enabled)
; - permit/deny - IP address filters
; - contactpermit/contactdeny - IP address filters for registrations
; - context - Which set of services you offer various users
;
; SIP dial strings
;-----------------------------------------------------------
; In the dialplan (extensions.conf) you can use several
; syntaxes for dialing SIP devices.
; SIP/devicename
; SIP/username@domain (SIP uri)
; SIP/username[:password[:md5secret[:authname[:transport]]]]@host[:port]
; SIP/devicename/extension
; SIP/devicename/extension/IPorHost
; SIP/username@domain//IPorHost
;
;
; Devicename
; devicename is defined as a peer in a section below.
;
; username@domain
; Call any SIP user on the Internet
; (Don’t forget to enable DNS SRV records if you want to use this)
;
; devicename/extension
; If you define a SIP proxy as a peer below, you may call
; SIP/proxyhostname/user or SIP/user@proxyhostname
; where the proxyhostname is defined in a section below
; This syntax also works with ATA’s with FXO ports
;
; SIP/username[:password[:md5secret[]]]@host[:port]
; This form allows you to specify password or md5secret and authname
; without altering any authentication data in config.
; Examples:
;
; SIP/*98@mysipproxy
; SIP/sales:topsecret::account02@domain.com:5062
; SIP/12345678::bc53f0ba8ceb1ded2b70e05c3f91de4f:myname@192.168.0.1
;
; IPorHost
; The next server for this call regardless of domain/peer
;
; All of these dial strings specify the SIP request URI.
; In addition, you can specify a specific To: header by adding an
; exclamation mark after the dial string, like
;
; SIP/sales@mysipproxy!sales@edvina.net
;
; A new feature for 1.8 allows one to specify a host or IP address to use
; when routing the call. This is typically used in tandem with func_srv if
; multiple methods of reaching the same domain exist. The host or IP address
; is specified after the third slash in the dialstring. Examples:
;
; SIP/devicename/extension/IPorHost
; SIP/username@domain//IPorHost
;
; CLI Commands
; -------------------------------------------------------------
; Useful CLI commands to check peers/users:
; sip show peers Show all SIP peers (including friends)
; sip show registry Show status of hosts we register with
;
; sip set debug on Show all SIP messages
;
; sip reload Reload configuration file
; sip show settings Show the current channel configuration
;
;------- Naming devices ------------------------------------------------------
;
; When naming devices, make sure you understand how Asterisk matches calls
; that come in.
; 1. Asterisk checks the SIP From: address username and matches against
; names of devices with type=user
; The name is the text between square brackets [name]
; 2. Asterisk checks the From: addres and matches the list of devices
; with a type=peer
; 3. Asterisk checks the IP address (and port number) that the INVITE
; was sent from and matches against any devices with type=peer
;
; Don’t mix extensions with the names of the devices. Devices need a unique
; name. The device name is not used as phone numbers. Phone numbers are
; anything you declare as an extension in the dialplan (extensions.conf).
;
; When setting up trunks, make sure there’s no risk that any From: username
; (caller ID) will match any of your device names, because then Asterisk
; might match the wrong device.
;
; Note: The parameter “username” is not the username and in most cases is
; not needed at all. Check below. In later releases, it’s renamed
; to “defaultuser” which is a better name, since it is used in
; combination with the “defaultip” setting.
;-----------------------------------------------------------------------------

; ** Old configuration options **
; The “call-limit” configuation option is considered old is replaced
; by new functionality. To enable callcounters, you use the new
; “callcounter” setting (for extension states in queue and subscriptions)
; You are encouraged to use the dialplan groupcount functionality
; to enforce call limits instead of using this channel-specific method.
; You can still set limits per device in sip.conf or in a database by using
; “setvar” to set variables that can be used in the dialplan for various limits.

[general]
context=default ; Default context for incoming calls
;allowguest=no ; Allow or reject guest calls (default is yes)
; If your Asterisk is connected to the Internet
; and you have allowguest=yes
; you want to check which services you offer everyone
; out there, by enabling them in the default context (see below).
;match_auth_username=yes ; if available, match user entry using the
; ‘username’ field from the authentication line
; instead of the From: field.
allowoverlap=no ; Disable overlap dialing support. (Default is yes)
;allowtransfer=no ; Disable all transfers (unless enabled in peers or users)
; Default is enabled. The Dial() options ‘t’ and ‘T’ are not
; related as to whether SIP transfers are allowed or not.
;realm=mydomain.tld ; Realm for digest authentication
; defaults to “asterisk”. If you set a system name in
; asterisk.conf, it defaults to that system name
; Realms MUST be globally unique according to RFC 3261
; Set this to your host name or domain name
;domainsasrealm=no ; Use domans list as realms
; You can serve multiple Realms specifying several
; ‘domain=…’ directives (see below).
; In this case Realm will be based on request ‘From’/‘To’ header
; and should match one of domain names.
; Otherwise default ‘realm=…’ will be used.

; With the current situation, you can do one of four things:
; a) Listen on a specific IPv4 address. Example: bindaddr=192.0.2.1
; b) Listen on a specific IPv6 address. Example: bindaddr=2001:db8::1
; c) Listen on the IPv4 wildcard. Example: bindaddr=0.0.0.0
; d) Listen on the IPv4 and IPv6 wildcards. Example: bindaddr=::
; (You can choose independently for UDP, TCP, and TLS, by specifying different values for
; “udpbindaddr”, “tcpbindaddr”, and “tlsbindaddr”.)
; (Note that using bindaddr=:: will show only a single IPv6 socket in netstat.
; IPv4 is supported at the same time using IPv4-mapped IPv6 addresses.)
;
; You may optionally add a port number. (The default is port 5060 for UDP and TCP, 5061
; for TLS).
; IPv4 example: bindaddr=0.0.0.0:5062
; IPv6 example: bindaddr=[::]:5062
;
; The address family of the bound UDP address is used to determine how Asterisk performs
; DNS lookups. In cases a) and c) above, only A records are considered. In case b), only
; AAAA records are considered. In case d), both A and AAAA records are considered. Note,
; however, that Asterisk ignores all records except the first one. In case d), when both A
; and AAAA records are available, either an A or AAAA record will be first, and which one
; depends on the operating system. On systems using glibc, AAAA records are given
; priority.

udpbindaddr=0.0.0.0 ; IP address to bind UDP listen socket to (0.0.0.0 binds to all)
; Optionally add a port number, 192.168.1.1:5062 (default is port 5060)

; When a dialog is started with another SIP endpoint, the other endpoint
; should include an Allow header telling us what SIP methods the endpoint
; implements. However, some endpoints either do not include an Allow header
; or lie about what methods they implement. In the former case, Asterisk
; makes the assumption that the endpoint supports all known SIP methods.
; If you know that your SIP endpoint does not provide support for a specific
; method, then you may provide a comma-separated list of methods that your
; endpoint does not implement in the disallowed_methods option. Note that
; if your endpoint is truthful with its Allow header, then there is no need
; to set this option. This option may be set in the general section or may
; be set per endpoint. If this option is set both in the general section and
; in a peer section, then the peer setting completely overrides the general
; setting (i.e. the result is not the union of the two options).
;
; Note also that while Asterisk currently will parse an Allow header to learn
; what methods an endpoint supports, the only actual use for this currently
; is for determining if Asterisk may send connected line UPDATE requests. Its
; use may be expanded in the future.
;
; disallowed_methods = UPDATE

;
; Note that the TCP and TLS support for chan_sip is currently considered
; experimental. Since it is new, all of the related configuration options are
; subject to change in any release. If they are changed, the changes will
; be reflected in this sample configuration file, as well as in the UPGRADE.txt file.
;
tcpenable=no ; Enable server for incoming TCP connections (default is no)
tcpbindaddr=0.0.0.0 ; IP address for TCP server to bind to (0.0.0.0 binds to all interfaces)

;tlsbindaddr=0.0.0.0 ; IP address for TLS server to bind to (0.0.0.0) binds to all interfaces)
; Optionally add a port number, 192.168.1.1:5063 (default is port 5061)
; Remember that the IP address must match the common name (hostname) in the

;tcpauthtimeout = 30 ; tcpauthtimeout specifies the maximum number

; Specifying a port in a SIP peer definition or

; Codec negotiation
;
; When Asterisk is receiving a call, the codec will initially be set to the

; that the caller also indicates that it supports. But, after the caller
; starts sending RTP, Asterisk will switch to using whatever codec the caller
; is sending.
;
; When Asterisk is placing a call, the codec used will be the first codec in

;dynamic_exclude_static = yes ; Disallow all dynamic hosts from registering

;contactdeny=0.0.0.0/0.0.0.0 ; Use contactpermit and contactdeny to

; Multiple contexts may be specified by separating them with ‘&’. The
; actual extension is the ‘regexten’ parameter of the registering peer or its
; name if ‘regexten’ is not provided. If more than one context is provided,
; the context must be specified within regexten by appending the desired
; context after ‘@’. More than one regexten may be supplied if they are

;
;regcontext=sipregistrations
;regextenonqualify=yes ; Default “no”
; If you have qualify on and the peer becomes unreachable
; this setting will enforce inactivation of the regexten
; extension for the peer

;----------------------------------- MEDIA HANDLING --------------------------------
; By default, Asterisk tries to re-invite media streams to an optimal path. If there’s
; no reason for Asterisk to stay in the media path, the media will be redirected.
; This does not really work well in the case where Asterisk is outside and the
; clients are on the inside of a NAT. In that case, you want to set directmedia=nonat.
;
;directmedia=yes ; Asterisk by default tries to redirect the
; RTP media stream to go directly from
; the caller to the callee. Some devices do not
; support this (especially if one of them is behind a NAT).
; The default setting is YES. If you have all clients
; behind a NAT, or for some other reason want Asterisk to
; stay in the audio path, you may want to turn this off.

                            ; This setting also affect direct RTP
                            ; at call setup (a new feature in 1.4 - setting up the
                            ; call directly between the endpoints instead of sending
                            ; a re-INVITE).

                            ; Additionally this option does not disable all reINVITE operations.
                            ; It only controls Asterisk generating reINVITEs for the specific
                            ; purpose of setting up a direct media path. If a reINVITE is
                            ; needed to switch a media stream to inactive (when placed on
                            ; hold) or to T.38, it will still be done, regardless of this 
                            ; setting. Note that direct T.38 is not supported.

;directmedia=nonat ; An additional option is to allow media path redirection
; (reinvite) but only when the peer where the media is being
; sent is known to not be behind a NAT (as the RTP core can
; determine it based on the apparent IP address the media
; arrives from).

;directmedia=update ; Yet a third option… use UPDATE for media path redirection,
; instead of INVITE. This can be combined with ‘nonat’, as
; ‘directmedia=update,nonat’. It implies ‘yes’.

;directrtpsetup=yes ; Enable the new experimental direct RTP setup. This sets up
; the call directly with media peer-2-peer without re-invites.
; Will not work for video and cases where the callee sends
; RTP payloads and fmtp headers in the 200 OK that does not match the
; callers INVITE. This will also fail if directmedia is enabled when
; the device is actually behind NAT.

;directmediadeny=0.0.0.0/0 ; Use directmediapermit and directmediadeny to restrict
;directmediapermit=172.16.0.0/16; which peers should be able to pass directmedia to each other
; (There is no default setting, this is just an example)
; Use this if some of your phones are on IP addresses that
; can not reach each other directly. This way you can force
; RTP to always flow through asterisk in such cases.

;ignoresdpversion=yes ; By default, Asterisk will honor the session version
; number in SDP packets and will only modify the SDP
; session if the version number changes. This option will
; force asterisk to ignore the SDP session version number
; and treat all SDP data as new data. This is required
; for devices that send us non standard SDP packets
; (observed with Microsoft OCS). By default this option is
; off.

;sdpsession=Asterisk PBX ; Allows you to change the SDP session name string, (s=)
; Like the useragent parameter, the default user agent string
; also contains the Asterisk version.
;sdpowner=root ; Allows you to change the username field in the SDP owner string, (o=)
; This field MUST NOT contain spaces
;encryption=no ; Whether to offer SRTP encrypted media (and only SRTP encrypted media)
; on outgoing calls to a peer. Calls will fail with HANGUPCAUSE=58 if
; the peer does not support SRTP. Defaults to no.

;------------------------------------------------------------------------------
; DEVICE CONFIGURATION
;
; The SIP channel has two types of devices, the friend and the peer.
; * The type=friend is a device type that accepts both incoming and outbound calls,
; where Asterisk match on the From: username on incoming calls.
; (A synonym for friend is “user”). This is a type you use for your local
; SIP phones.
; * The type=peer also handles both incoming and outbound calls. On inbound calls,
; Asterisk only matches on IP/port, not on names. This is mostly used for SIP
; trunks.
;
; For device names, we recommend using only a-z, numerics (0-9) and underscore
;
; For local phones, type=friend works most of the time
;
; If you have one-way audio, you probably have NAT problems.
; If Asterisk is on a public IP, and the phone is inside of a NAT device
; you will need to configure nat option for those phones.
; Also, turn on qualify=yes to keep the nat session open
;
