Re: [Linphone-developers] Using SIPAddHeader to force Auto-answer

[Matt Murphy]

As an addendum to my previous post, I found a function linphone_call_asked_to_autoanswer() function in coreapi/linphonecore.c. However, I cannot find any evidence that this function is ever called. I feel like this is on the correct path, but I am unsure of how (or where) to utilize it in order to enable auto-answer upon receiving an instruction in the SIP Header.

Has anyone had any experience with this?

Thanks,

Greetings everyone,

I am attempting to page my linphone appliance (connected to an Asterisk server) by dialing a special extension. The trouble is that when I use the Asterisk Page() command, my linphone appliance rings. I would like linphone to auto-answer the page. I searched around and found some information on this from back in 2010:

[Linphone-developers] autoanswer and answer-after=0

This appears to be exactly what I am looking for - in essence, a way to inject the auto-answer behaviour into the SIP header. 

I tried adding the following to my Asterisk extensions.conf file:

exten => 333,1,Verbose(Paging)

same => n,SIPAddHeader(Call-Info: answer-after=0)

same => n,Set(PageExts=PJSIP/6003&PJSIP/6010)

same => n,Page(${PageExts},i,120)

I guess my question is two-fold:

1) Is this behaviour supported by linphone?

2) Am I correctly invoking the auto-answer by what I have above?

Thank you for all your help,
