             Summary: pjsip: Switching from directmedia to T.38 doesn't use correct contact addresses.
                 Key: ASTERISK-27089
                 URL: https://issues.asterisk.org/jira/browse/ASTERISK-27089
             Project: Asterisk
          Issue Type: Bug
      Security Level: None
          Components: Bridges/bridge_native_rtp, Channels/chan_pjsip
    Affects Versions: 13.16.0
            Reporter: Richard Mudgett


If direct media is established before a T.38 reinvite switch is requested, chan_pjsip does not use the correct contact address.  It continues to use the remote addresses even thought the UDPTL ports are local.

Scenario:
# A calls B
# Asterisk reinvites A and B to send media directly between A and B
# A or B initiates a reinvite to start T.38
# The contact addresses used by Asterisk in the T.38 reinvites are still the direct media addresses of A and B instead of Asterisk's own address while the T.38 stream's ports are Asterisk's port for the UDPTL traffic.

The attached testsuite test logs for chan_sip and chan_pjsip show that chan_sip uses the expected address while chan_pjsip uses the wrong addresses.
