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

             Summary: "Contact"  in sip INVITES is garbled
                 Key: ASTERISK-25741
                 URL: https://issues.asterisk.org/jira/browse/ASTERISK-25741
             Project: Asterisk
          Issue Type: Bug
      Security Level: None
          Components: pjproject/pjsip
    Affects Versions: 13.1.0
         Environment: CentOS 2.6.32-504.23.4.el6.i686
            Reporter: Oliver Nauliv


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.
