             Summary: Incorrect Behavior for rewrite_contact when Re-Invite omits routset
                 Key: ASTERISK-28129
                 URL: https://issues.asterisk.org/jira/browse/ASTERISK-28129
             Project: Asterisk
          Issue Type: Bug
      Security Level: None
          Components: Resources/res_pjsip_nat
    Affects Versions: 13.24.0
            Reporter: Torrey Searle


A routeset cannot be modified after the a SIP Dialog is created, thus the appearance of Record-Route headers in REINVITES is optional.

res_pjsip_nat is designed to update the contact with received ip if there is no routset, and the topmost route header if there is a routset.  However if a re-invite omits adding Record-Route headers on a dialog that has a routset, res_pjsip_nat incorrectly updates the contact header causing subsequent messages asterisk sends to no be routed correctly.
