Channel 'DAHDI/1-1' sent into invalid extension 's' in conte

Asterisk Asterisk Support

Hi i am setting up a very simple asterisk system with 1 analog trunk and a few SIP extensions.

When calls are incoming on the trunk, they should be forwarded to SIP/101.

I have setup a basic and without any doubt incorrect config, and i am getting the following errors:

Agent policy for SIP/101-00000000 is ‘never’. CC not possible
Channel ‘DAHDI/1-1’ sent into invalid extension ‘s’ in context ‘default’, but no invalid handler

My config is as follows:

cat chan_dahdi.conf

[channels]
#include dahdi-channels.conf
[root@asterisk asterisk]# cat dahdi-channels.conf

; send to trunk

[local]
exten => s,1,Dial(SIP/101)

[frm-pstn]
include => outgoing
include => local

I have a few questions:

What context should i use for the incoming calls? from-pstn, or default? When showing dahdi channels the context there is shown as from-pstn and also default.

Secondly, what does it mean when i get the warning: Agent policy for SIP/101-00000000 is ‘never’. CC not possible

Finally, any idea why my config doesnt work and i get bombed out with Channel ‘DAHDI/1-1’ sent into invalid extension ‘s’ in context ‘default’, but no invalid handler

Appreciate the help in getting my very first test install off the ground. Many thanks in advance.

The context you reference in your chan_dahdi.conf is called “from-pstn:”

[root@asterisk asterisk]# cat dahdi-channels.conf
; Autogenerated by /usr/sbin/dahdi_genconf on Mon Dec 20 07:45:27 2010
; Span 1: WCTDM/0 "Wildcard TDM410P Board 1" (MASTER)
;;; line="1 WCTDM/0/0 FXSLS (In use)"
signalling=fxs_ks
callerid=asreceived
group=0
context=from-pstn
channel => 1
callerid=
group=
context=default

But, your dialplan is configured to use a context called “frm-pstn” e.g.:

[frm-pstn]
include => outgoing
include => local

So, your incoming calls are going to the non-existant, presently, “default” context.

Change your dialplan to read [from-pstn] instead and you should be right as rain.

Cheers.
