             Summary: res_pjsip_multihomed: SDP rewriting with different IP version
                 Key: ASTERISK-26379
                 URL: https://issues.asterisk.org/jira/browse/ASTERISK-26379
             Project: Asterisk
          Issue Type: Bug
      Security Level: None
          Components: Resources/res_pjsip_multihomed
    Affects Versions: 14.0.0-beta2
            Reporter: Joshua Colp


Asterisk 14 now has proper DNS support. This is great! We use IPv6 when available, TCP, TLS, etc. Unfortunately we don't have dual stack support for the RTP portion yet. This means that SDP can only stay on the IP protocol that it was originally set up with. We can't change it if the message ends up going out using a different protocol (ie: we aren't set to explicitly use RTP IPv6 but resolution results in us going out IPv6 for signaling).

Right now res_pjsip_multihomed just rewrites the SDP connection address without regard, resulting in an IP4 with an IPv6 address.
