CISCO 7906G and Paging with Asterisk

[aljalmody]

I need help on how setup Cisco 7906G IP Phone to receive paging from Asterisk.

On other SIP phones I used to do that by setting the parameter “Allow Auto Answer by Call-Info:” to yes in the phone configuration then set the SIP header in Asterisk dialplan with :

exten => *7778,1,SipAddHeader(Call-Info: <uri>\;answer-after=0)

Any idea how to achieve similar setup with Cisco 7906G IP Phones?

You will not find much help here for using Cisco IP phones with third-party IP PBX. You can look at sites like voip-info.org, or similar.

Thank you for the hint.

Jalmod,

I don't recall our Cisco Phones supported to do paging via SIP headers.

Usually our 3rd Party implements paging systems via HTTP POST to the phones with specially constructed XML instructions for the phone to open a Multicast Channel to the Multicast source of the paging system.

You might want to develop this via an AGI script that performs the HTTP POST to the phone and look at the Phone Services SDK that Cisco releases to the Public.

Many thanks for your replay.

There is parameter in the SEP{MAC}.cnf.xml file that was set to "2" (see below), what are the other possible options?

Is there any other parameter in this file related to “Allow Auto Answer by Call-Info:”?
