Hi all,

This is a followup from my “Getting around semi-colons” question.

I’ve specified:
contact_user
234567\;tgrp
234567\;trunkcontext=telecom.co.nz under my registration section for the trunk.

This is all fine and I successfully got Asterisk 13 + pjsip registered to our BroadWorks-based provider. However, I see the contact_user field only gets used upon registration, and not during an INVITE.

During Registration:

Contact:

During INVITE:

Contact:

The only questions I have is:
1. Is this expected/known behaviour? eg. pjsip won’t use the contact user for anything else?
2. If not, where should I be specifying the contact_user to make pjsip use it in INVITEs? Is this where the AoRs come in?
3. Are those Contact headers used for some internal reference/record keeping for the calls? Or…
4. Can I mess with the Contact Header with the PJSIP_HEADER function?

Thanks again for the help, just wrapping my head around this new channel driver 🙂
