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

             Summary: RFC3581 compliance
                 Key: ASTERISK-25071
                 URL: https://issues.asterisk.org/jira/browse/ASTERISK-25071
             Project: Asterisk
          Issue Type: Bug
      Security Level: None
          Components: Channels/chan_sip/Registration
    Affects Versions: 13.3.2
         Environment: CentOS 6.5
            Reporter: Oleg Rabinovich


I am connecting to Asterisk via Kamailio SIP proxy (version 4.2.3). The client, MicroSIP-3.6.3 is behind NAT. Kamailio SIP proxy adds ";rport" to via headers in order to receive the traffic back from the server, according to RFC 3581. However, I fail to dial that client, as Asterisk dials directly to the client (public address) instead of my Kamailio box. This issue is similar to ASTERISK-7276, however, it's different in the sense that SIP request (INVITE) that is not routed correctly is a separate request from the one (REGISTER) that includes ";rport".

I am attaching a patch that fixes the issue in my environment. Please, review it and let me know if this is a correct direction or am I missing something.
