[SOLVED]Page application problem

Asterisk Asterisk Support
1

Hello everyone,

I want to implement paging function with a set of GXV3240 with auto-answer, to be used as public address system. I have been following Asterisk™: The Definitive Guide available on asteriskdocs.org and information found on voip-info.org. I’ve came up with following Dialplan code:

exten => 2001,1,Verbose(2,Paging a group of Grandstreams)
  same => n, SIPAddHeader(Call-Info: answer-after=0)
  same => n, Page(SIP/000b82672bef-1&SIP/000b82672bf4-1)

When I want to execute this extension I get the following CLI output:

== Using SIP VIDEO CoS mark 6 == Using SIP RTP CoS mark 5 -- Executing [2001@LocalSets:1] Verbose("SIP/f8a9d052a660-00000071", "2,Paging a group of Grandstreams") in new stack == Paging a group of Grandstreams -- Executing [2001@LocalSets:2] SIPAddHeader("SIP/f8a9d052a660-00000071", "Call-Info: answer-after=0") in new stack -- Executing [2001@LocalSets:3] Page("SIP/f8a9d052a660-00000071", "SIP/000b82672bef-1&SIP/000b82672bf4-1") in new stack == Spawn extension (LocalSets, 2001, 3) exited non-zero on 'SIP/f8a9d052a660-00000071'

I am using Asterisk 11.13.1, currently without MeetMe installed, as I have read that it is not required for Page() in this version. (although I’ve tried to do it with DAHDI and MeetMe, and it still yielded the same results)

Auto answer works fine with Grandstreams when using Dial() application.

I don’t know what to try next, so any help appreciated!

Edit:
Wireshark shows that asterisk does not even send SIP request to the Grandstream phones:

SOLUTION:: confbridge.conf file needs to be present
