------------------------------------------

Hello Joshua,

Thanks again for responding to the message. Here are 2 short questions, taking aside the SIP RFC for just a moment. 

1) Why do all the other Asterisk PBX (not using PJSIP) don't garble the Contact field ? And can we just have an option to keep the Contact field intact the way it has always been ?

2) Why is the P-Asserted-Identity not working? I did everything suggested on https://community.asterisk.org/t/asterisk-13-pjsip-contact-field-in-sip-is-randomized/65044 and packaging it into a pre-dialer, but the field is still not showing up.

Please advise. The carrier and I have been working on this issue for 20+ combined hours... we are both willing to work with the Asterisk team to help get this resolved and help the community, as apparently other people are reporting similar issues on the forums.

Is there an e-mail I can send the full unedited SIP trace, as it contains private information ?

Thanks!

> Hello,
> Using Asterisk 13.1-cert2 and PJSIP, with Nextiva as the SIP Trunk provider. The carrier says that there are 2 reasons why dialing out is not working :
> 1) If you look at the SIP trace below, the carrier is indicating that the reason for not working is because the "Contact:" line has a cryptic-randomized number in there, instead of the actual contact.
> It sends:
> Contact: <sip:ec89dc3e-90df-4fbd-99bd-f5b225f8da3d at 107.207.90.90:5060>
> Instead of sending:
> Contact: <sip:7143861212 at 107.207.90.90:5060>
> 2) We are unable to send the X-P-Asserted-Identity, because while the dialplan runs PJSIP_HEADER without error, the option doesn't make it into the SIP packet.
