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

             Summary: PJSIP compose invalid request-URI in ACK for re-INVITE 
                 Key: ASTERISK-28406
                 URL: https://issues.asterisk.org/jira/browse/ASTERISK-28406
             Project: Asterisk
          Issue Type: Bug
      Security Level: None
          Components: pjproject/pjsip
    Affects Versions: 15.7.2
            Reporter: Dang Thanh Loi
            Severity: Minor


I'm working with `moh_passthrough = yes` for asterisk lies between an UA and a Proxy loose routing.
The call flow
UA1 <-> Asterisk <-> Proxy (kamailio) <-> UA2
and things go wrong for the call between Asterisk and UA2 (via Proxy) when receive re-INVITE hold from UA1

Asterisk supposes to place the UA2's Contact in the R-URI header for subsequent in-dialog requests sent to the proxy. Asterisk does well for the ACK corresponding to the initial INVITE, but for subsequent re-INVITEs (and their ACKs), Asterisk placed the Proxy's Contact into the R-URI which make them not routable.
