[OpenSIPS-Users] Voicemail doesn't work with Mediaproxy

[osiris123d]

Fixed the issue.  You were right.  usemediaproxy wasn't getting called
because in the onreply route the first IF statement was never true because
bflag6 or bflag7 were never being set.  So here is what I did to fix the
issue.


failure_route[1] {
        ##--
        ##-- If cancelled, exit. 
        ##--
        if (t_was_cancelled()) {
                exit;
        };
        ##--
        ##-- If busy send to the e-mail server, prefix the "b"
        ##-- character to indicate busy. 
        ##--
        if (t_check_status("486")) {
                revert_uri();

		append_hf("P-App-Name: voicemail\r\nP-App-Param:
Email-Address=blah.blahmail.com;Mode=both;usr=$tU;dom=@$td\r\n");

                rewritehostport("VoicemailIP");
#               append_branch();   <---------DELETED this
setbflag(6);
                route(1);
                exit;
        };
        ##--
        ##-- If timeout (408) or unavailable temporarily (480),
        ##-- prefix the uri with the "u"character to indicate 
        ##-- unanswered and send to the e-mail
        ##-- sever
        ##--
        if (t_check_status("408") || t_check_status("480")) {
                revert_uri();

		append_hf("P-App-Name: voicemail\r\nP-App-Param:
Email-Address=blah.blahmail.com;Mode=both;usr=$tU;dom=@$td\r\n");

                rewritehostport("VoicemailIP");
#                append_branch();   <---------Deleted this
setbflag(6);
                route(1);
                exit;
        };
}



Thanks for the hint.  This made me go back and re-read up on OpenSIPS
routing and really understand the routing logic.  Thanks again.
