[SOLVED] Zulu incoming call auto-answer (PJSIP)

Commercial Modules Zulu
1

Hi I’m trying to get Zulu to auto-answer call sent to it from a custom dialplal. Here is what I tried:

exten => s,n,Set(PJSIP_HEADER(add,Alert-info)=“answer-after = 0”)
exten => s,n,Set(PJSIP_HEADER(add,Alert-info)=“info = alert-autoanswer”)
exten => s,n,Set(PJSIP_HEADER(add,Alert-info)=“Auto Answer”)
exten => s,n,Dial(Local/90${agents_extension}@zulu-call,35,HhtrIb(func-apply-sipheaders^s^1))

I see the code properly executes in the logs:

The Zulu client rings but does not auto-answer.

The func-apply-sipheaders is part of freePBX ans seems to be required for the CRM URL to properly work with Zulu.

Any idea how to get the Zulu Client to auto-answer ?

Thanks.

And it’s just now that I see the error messages…

res_pjsip_header_funcs.c: This function requires a PJSIP channel.

Ok. I’ll dig that first and report here…

Not many softphones support SIP Headers to auto answer. I am not sure if Sangoma supports auto answer on their soft sip clients.

Anyway, not sure if you use Zulu mobile, if so, you should replace it with SangomConnect.

According to this Zulu Client supports it since version 3.2.3:

But no details about the specific header to use…

I modified my dialplan after looking up the errors and how it’s implemented in freePBX:

exten => s,n,GoSub(func-set-sipheader,s,1(Alert-Info,"answer-after = 0"))
exten => s,n,Dial(Local/90${agents_extension}@zulu-call,35,HhtrIb(func-apply-sipheaders^s^1))

Waiting for feedback from someone in my team to test it.

Ok so I got it to work. The proper dialplan code is:

exten => s,n,GoSub(func-set-sipheader,s,1(Alert-Info,"Auto Answer"))
exten => s,n,Dial(Local/90${agents_extension}@zulu-call,35,HhtrIb(func-apply-sipheaders^s^1))
