asterisk users - Oct 2011 - Calls from PSTN on SPA3102

Hello list, this is my first post on this list.

I have a server with Asterisk and a Linksys SPA3102 with 3 SIP phones.
I have configured the SPA PSTN line as trunk to receive and send
calls.

I can call outside from SIP phone throw the PSTN line and all is OK,
the problem is when I receive a call from the PSTN, on the out caller
phone there is a demo playback. I want to redirect the call to a
internal SIP phone.

This is the extensions.conf:

[spa]
include => saliente_pstn
include => entradas_pstn
include => sips

[saliente_pstn]
exten => _9ZXXXXXXX,1,Dial(SIP/${EXTEN}@pstn,60,)
exten => _9ZXXXXXXX,n,Hangup

[entradas_pstn]
exten => s,1,Dial(SIP/103,20,tm)
exten => s,2,VoiceMail(103)
exten => s,3,Hangup

[sips]
exten => 100,1,Dial(SIP/100,20,Ttm) ; extensi?n 100
exten => 100,2,Voicemail(100)
exten => 100,3,Hangup
exten => 101,1,Dial(SIP/101,20,Ttm) ; extensi?n 101
exten => 101,2,Voicemail(101)
exten => 101,3,Hangup
exten => 102,1,Dial(SIP/102,20,Ttm) ; extensi?n 102
exten => 102,2,Voicemail(102)
exten => 102,3,Hangup
exten => 103,1,Dial(SIP/103,20,Ttm) ; extensi?n 103
exten => 103,2,Voicemail(103)
exten => 103,3,Hangup

When I receive a call from outside this is the asterisk console log:

How could I make to redirect the call to the 103 extension?

Thanks for your help, best regards.

Hi Josu,
> How could I make to redirect the call to the 103 extension?
In the sip.conf you have to put the correct context of your
SPA3102-peer/friend. So put a line like

context=entradas_pstn

there. That should get it out of the "default" context it is now going
to. Your "s" extension in entradas_pstn is already dialling to SIP/103
so that should be OK.
