Hi, this problem appears when I activate call forwarding (freepbx 14 and asterisk 16).
Our provider requires a certain value in the PJSIP P-Asserted-Identity (PAI) header and rejects invites otherwise.
When I do regular outgoing calls, the PAI value is ok and it works. (I use sngrep)
When I activate call forwarding in an extension, the PAI header suddenly contains the CID of the incoming call hat is being forwarded and the forwarded call then is rejected.
I am looking for the best way to leave the PAI header untouched or to manipulate it to the correct value. I have checked
the [macro-dialout-trunk-predial-hook] unfortunately doesn’t seem the right place to do this. I can’t modify the [func-apply-sipheaders] context because it is always overwritten when I start a new session. I could maybe configure in the [func-apply-sipheaders-custom] but don’t quite understand how to reach it.
Any help is appreciated!
