Cisco 7911 with SIP - can't dial but can answer

brii · September 27, 2015, 7:43pm

Hello!

I’am fighting with this problem from 2 days and have no idea how to resolv it…
I’am trying to use Cisco 7911 phones with Asterisk. On configuration with works correctly with softphones I connect Cisco phones and gave Cisco phones settings from softphones. Hardphones are registered correctly. I can dial from softphones to Cisco and make normal conversation. But if i try to call from Cisco to Cisco or softphone I hear busy signal after I press first digit of phone numer (6 or 1) and get in console “== Using SIP RTP CoS mark 5”. When I press numer 2 (or 3,4,5,7,8,9,0) i get:
NOTICE[15248][C-0000001a]: chan_sip.c:25628 handle_request_invite: Call from ‘108’ (192.168.211.132:49155) to extension ‘2’ rejected because extension not found in context ‘from-internal’.
== Using SIP RTP CoS mark 5

6004 and 6005 are softphones,

Please help.

Anyone something?

david55 · October 2, 2015, 4:28pm

The log doesn’t match the error message, but you have neither an extension 2 nor an extension 6 defined in your dialplan.

You are getting address incomplete for 6, rather than not found in context, because you do have some numbers beginning with 6. Maybe the phone has a bad dialplan and is sending the number too soon.

Also, having from-internal as your default context is bad security practice. The default context should not be able to make any toll calls.

brii · October 11, 2015, 8:41am

Yes, it was the problem - I need to modified dialplan.xml in phones to wait for full number.

Thanks for information, this configuration was created only for testing
