; Enable echo cancellation
; Use either “yes”, “no”, or a power of two from 32 to 256 if you wish to
; actually set the number of taps of cancellation.
;
; Note that when setting the number of taps, the number 256 does not translate
; to 256 ms of echo cancellation. echocancel=256 means 256 / 8 = 32 ms.
;
; Note that if any of your DAHDI cards have hardware echo cancellers,
; then this setting only turns them on and off; numeric settings will
; be treated as “yes”. There are no special settings required for
; hardware echo cancellers; when present and enabled in their kernel
; modules, they take precedence over the software echo canceller compiled
; into DAHDI automatically.
;
;
echocancel=yes
;
; Some DAHDI echo cancellers (software and hardware) support adjustable
; parameters; these parameters can be supplied as additional options to
; the ‘echocancel’ setting. Note that Asterisk does not attempt to
; validate the parameters or their values, so if you supply an invalid
; parameter you will not know the specific reason it failed without
; checking the kernel message log for the error(s) put there by DAHDI.
;
;echocancel=128,param1=32,param2=0,param3=14
;
; Generally, it is not necessary (and in fact undesirable) to echo cancel when
; the circuit path is entirely TDM. You may, however, change this behavior
; by enabling the echo canceller during pure TDM bridging below.
;
echocancelwhenbridged=yes
;
; In some cases, the echo canceller doesn’t train quickly enough and there
; is echo at the beginning of the call. Enabling echo training will cause
; DAHDI to briefly mute the channel, send an impulse, and use the impulse
; response to pre-train the echo canceller so it can start out with a much
; closer idea of the actual echo. Value may be “yes”, “no”, or a number of
; milliseconds to delay before training (default = 400)
;
; WARNING: In some cases this option can make echo worse! If you are
; trying to debug an echo problem, it is worth checking to see if your echo
; is better with the option set to yes or no. Use whatever setting gives
; the best results.
;
; Note that these parameters do not apply to hardware echo cancellers.

;
; You may also set the default receive and transmit gains (in dB)
;
; Gain Settings: increasing / decreasing the volume level on a channel.
; The values are in db (decibells). A positive number
; increases the volume level on a channel, and a
; negavive value decreases volume level.
;
; Dynamic Range Compression: you can also enable dynamic range compression
; on a channel. This will amplify quiet sounds while leaving
; louder sounds untouched. This is useful in situations where
; a linear gain setting would cause clipping. Acceptable values
; are in the range of 0.0 to around 6.0 with higher values
; causing more compression to be done.
;
; There are several independent gain settings:
; rxgain: gain for the rx (receive - into Asterisk) channel. Default: 0.0
; txgain: gain for the tx (transmit - out of Asterisk Asterisk) channel.
; Default: 0.0
; cid_rxgain: set the gain just for the caller ID sounds Asterisk
; emits. Default: 5.0 .
; rxdrc: dynamic range compression for the rx channel. Default: 0.0

;
busydetect=yes
;
; If busydetect is enabled, it is also possible to specify how many busy tones

; will further reduce the chance of a false positive.
;

;
; NOTE: In make menuselect, you’ll find further options to tweak the busy

; When ‘faxdetect’ is used, one could use ‘faxbuffers’ to configure the DAHDI
; transmit buffer policy. The default is OFF. When this configuration
; option is used, the faxbuffer policy will be used for the life of the call
; after a fax tone is detected. The faxbuffer policy is reverted after the
; call is torn down. The sample below will result in 6 buffers and a full
; buffer policy.
;
;faxbuffers=>6,full
;
; Configure the default number of DAHDI buffers and the transmit policy to use.
; This can be used to eliminate data drops when scheduling jitter prevents
; Asterisk from writing to a DAHDI channel regularly. Most users will probably
; want “faxbuffers” instead of “buffers”.
;
; The policies are:
; immediate - DAHDI will immediately start sending the data to the hardware after
; Asterisk writes to the channel. This is the default mode. It
; introduces the least amount of latency but has an increased chance for
; hardware under runs if Asterisk is not able to keep the DAHDI write
; queue from going empty.
; half - DAHDI will wait until half of the configured buffers are full before
; starting to transmit. This adds latency to the audio but reduces
; the chance of under runs. Essentially, this is like an in-kernel jitter
; buffer.
; full - DAHDI will not start transmitting until all buffers are full.
; Introduces the most amount of latency and is susceptible to over
; runs from the Asterisk process.
;
; The receive policy is never changed. DAHDI will always pass up audio as soon
; as possible.
;
; The default number of buffers is 4 (from jitterbuffers) and the default policy
; is immediate.

; is of the form exten@context). When channels are needed the “idle” calls
; are disconnected (so long as there are at least “minidle” calls still

; be used only if the sending side can create and the receiving

; jbresyncthreshold = 1000 ; Jump in the frame timestamps over which the jitterbuffer is

; jbimpl = fixed ; Jitterbuffer implementation, used on the receiving side of a DAHDI
; channel. Two implementations are currently available - “fixed”
; (with size always equals to jbmax-size) and “adaptive” (with
; variable size, actually the new jb of IAX2). Defaults to fixed.
; jbtargetextra = 40 ; This option only affects the jb when ‘jbimpl = adaptive’ is set.
; The option represents the number of milliseconds by which the new
; jitter buffer will pad its size. the default is 40, so without
; modification, the new jitter buffer will set its size to the jitter
; value plus 40 milliseconds. increasing this value may help if your
; network normally has low jitter, but occasionally has spikes.
; jblog = no ; Enables jitterbuffer frame logging. Defaults to “no”.

; MFC-R2 signaling has lots of variants from country to country and even sometimes
; minor variants inside the same country. The only mandatory parameters here are:
; mfcr2_variant, mfcr2_max_ani and mfcr2_max_dnis.
; IT IS RECOMMENDED that you leave the default values (leaving it commented) for the
; other parameters unless you have problems or you have been instructed to change some
; parameter. OpenR2 library uses the mfcr2_variant parameter to try to determine the
; best defaults for your country, also refer to the OpenR2 package directory
; doc/asterisk/ where you can find sample configurations for some countries. If you
; want to contribute your configs for a particular country send them to the e-mail
; of the primary OpenR2 developer that you can find in the AUTHORS file of the OpenR2 package
; MFC/R2 variant. This depends on the OpenR2 supported variants
; A list of values can be found by executing the openr2 command r2test -l

; mfcr2_variant=mx
; Max amount of ANI to ask for
; mfcr2_max_ani=10
; Max amount of DNIS to ask for
; mfcr2_max_dnis=4
; whether or not to get the ANI before getting DNIS.
; some telcos require ANI first some others do not care
; if this go wrong, change this value
; mfcr2_get_ani_first=no
; Caller Category to send
; national_subscriber
; national_priority_subscriber
; international_subscriber
; international_priority_subscriber
; collect_call
; usually national_subscriber works just fine
; you can change this setting from the dialplan
; by setting the variable MFCR2_CATEGORY
; (remember to set _MFCR2_CATEGORY from originating channels)
; MFCR2_CATEGORY will also be a variable available in your context
; on incoming calls set to the value received from the far end
; mfcr2_category=national_subscriber
; Call logging is stored at the Asterisk
; logging directory specified in asterisk.conf
; plus mfcr2/

; remember to set mfcr2_call_files=yes
; mfcr2_logdir=span1
; whether or not to drop call files into mfcr2_logdir
; mfcr2_call_files=yes|no
; MFC/R2 valid logging values are: all,error,warning,debug,notice,cas,mf,stack,nothing
; error,warning,debug and notice are self-descriptive
; ‘cas’ is for logging ABCD CAS tx and rx
; ‘mf’ is for logging of the Multi Frequency tones
; ‘stack’ is for very verbose output of the channel and context call stack, only useful
; if you are debugging a crash or want to learn how the library works. The stack logging
; will be only enabled if the openr2 library was compiled with -DOR2_TRACE_STACKS
; You can mix up values, like: loglevel=error,debug,mf to log just error, debug and

; MFC/R2 value in milliseconds for the MF timeout. Any negative value
; means ‘default’, smaller values than 500ms are not recommended
; and can cause malfunctioning. If you experience protocol error

; mfcr2_mfback_timeout=-1
; MFC/R2 value in milliseconds for the metering pulse timeout.
; Metering pulses are sent by some telcos for some R2 variants
; during a call presumably for billing purposes to indicate costs,
; however this pulses use the same signal that is used to indicate
; call hangup, therefore a timeout is sometimes required to distinguish
; between a real hangup and a billing pulse that should not
; last more than 500ms, If you experience call drops after some
; minutes of being stablished try setting a value of some ms here,
; values greater than 500ms are not recommended.
; BE AWARE that choosing the proper protocol mfcr2_variant parameter
; implicitly sets a good recommended value for this timer, use this
; parameter only when you really want to override the default, otherwise
; just comment out this value or put a -1
; Any negative value means ‘default’.

; Brazil uses a special calling party category for collect calls (llamadas por cobrar)
; instead of using the operator (as in Mexico). The R2 spec in Brazil says a special GB tone
; should be used to reject collect calls. If you want to ALLOW collect calls specify ‘yes’,
; if you want to BLOCK collect calls then say ‘no’. Default is to block collect calls.
; (see also ‘mfcr2_double_answer’)
; mfcr2_allow_collect_calls=no
; This feature is related but independent of mfcr2_allow_collect_calls
; Some PBX’s require a double-answer process to block collect calls, if
; you ever have problems blocking collect calls using Group B signals (mfcr2_allow_collect_calls=no)
; then you may want to try with mfcr2_double_answer=yes, this will cause that every answer signal
; is changed by answer->clear back->answer (sort of a flash)
; (see also ‘mfcr2_allow_collect_calls’)
; mfcr2_double_answer=no
; This feature allows to skip the use of Group B/II signals and go directly
; to the accepted state for incoming calls
; mfcr2_immediate_accept=no
; You most likely dont need this feature. Default is yes.
; When this is set to yes, all calls that are offered (incoming calls) which
; DNIS is valid (exists in extensions.conf) and pass collect call validation
; will be accepted with a Group B tone (either call with charge or not, depending on mfcr2_charge_calls)
; with this set to ‘no’ then the call will NOT be accepted on offered, and the call will start its
; execution in extensions.conf without being accepted until the channel is answered (either with Answer() or
; any other application resulting in the channel being answered).
; This can be set to ‘no’ if your telco or PBX needs the hangup cause to be set accurately
; when this option is set to no you must explicitly accept the call with DAHDIAcceptR2Call
; or implicitly through the Answer() application.

; Brazil use a special signal to force the release of the line (hangup) from the
; backward perspective. When mfcr2_forced_release=no, the normal clear back signal
; will be sent on hangup, which is OK for all mfcr2 variants I know of, except for
; Brazilian variant, where the central will leave the line up for several seconds (30, 60)
; which sometimes is not what people really want. When mfcr2_forced_release=yes, a different
; signal will be sent to hangup the call indicating that the line should be released immediately
; mfcr2_forced_release=no
; Whether or not report to the other end ‘accept call with charge’
; This setting has no effect with most telecos, usually is safe
; leave the default (yes), but once in a while when interconnecting with
; old PBXs this may be useful.
; Concretely this affects the Group B signal used to accept calls
; The application DAHDIAcceptR2Call can also be used to decide this
; in the dial plan in a per-call basis instead of doing it here for all calls

; Configuration Sections
; ~~~~~~~~~~~~~~~~~~~~~~
; You can also configure channels in a separate chan_dahdi.conf section. In
; this case the keyword ‘channel’ is not used. Instead the keyword
; ‘dahdichan’ is used (as in users.conf) - configuration is only processed
; in a section where the keyword dahdichan is used. It will only be
; processed in the end of the section. Thus the following section:
;
;[phones]
;echocancel = 64
;dahdichan = 1-8
;group = 1
;
; Is somewhat equivalent to the following snippet in the section
; [channels]:
;
;echocancel = 64
;group = 1
;channel => 1-8
;
; When starting a new section almost all of the configuration values are
; copied from their values at the end of the section [channels] in
; chan_dahdi.conf and [general] in users.conf - one section’s configuration
; does not affect another one’s.
;
; Instead of letting common configuration values “slide through” you can
; use configuration templates to easily keep the common part in one
; place and override where needed.
