Add PJSIP_HEADER in call files?

Asterisk Asterisk Support

Hi,

Is there any way to add a pjsip header using call files?
I need to add this line PJSIP_HEADER(add,Call-Info)=;answer-after=0") so the phone can auto answer and call another extension.
I know I can do it with AMI, but I need to do it with the originate command or a call file.

All I got so far is this call file:

Channel:PJSIP/UT_4472
Callerid:Jack
WaitTime:10
MaxRetries:0
RetryTime:300
Context:internal
Extension:audio_alim
Priority:1
2

As usual, the solution is to invoke a local channel, rather than to directly dial the number.

Also that application adds a SIP header, using PJSIP; it doesn’t add a “PJSIP Header”.

I cannot get local channel to work. Do you have any example? Asterisk would be calling the extension then?

You are not currently calling an extension in Asterisk terms.

Thank you for for your help.
Here’s what works for me using local channel:

My call files:

Channel:Local/2005@internal
Callerid:Jack
WaitTime:60
MaxRetries:0
RetryTime:300
Context:internal
Extension:2010
Priority:1

My dialplan:

exten => 2005,1,NoOp(Internal calls)
same => n,Dial(PJSIP/2005,20,b(paging_handler^addheader^1))
same => n,Hangup()

;Predial handler
[paging_handler]
exten => addheader,1,Set(PJSIP_HEADER(add,Call-Info)=\;answer-after=0)
same => n,Return()
