Hi,

I’m migrating an old chan\_sip dialplan to a chan\_pjsip one and ran into issue. The current PBX dials like Dial(SIP/some.local.account&Local/101@external\_with\_variables), where the local channel sets couple of headers plus the CALLERID(num) before dialing the trunk.

With chan\_pjsip this scenario doesn’t work as the PJSIP\_HEADER function, which is required to set some trunk-specific headers, is not working on the Local channel as it requires a PJSIP one.

The end goal is to preserve the caller number for the softphone client and manipulate it just before dialing the trunk. Is it possible with chan\_pjsip?

The local channel needs to call the Dial for the chan\_pjsip endpoint using a pre-dial handler subroutine.
