[Serusers] [DONE] send BYE to SEMS

[Ezequiel Colombo]

Thanks Jan, i search in the sems list for syntax and implement the
"user_prefix_separator" in my sems.cfg.

SEMS prepend a "voicemail[user_prefix_separator] in the Contact URI for the
ACK and 200OK responses sent to the caller, so i make this configuration in
my ser.cfg for relay BYE to SEMS

        if (method=="BYE") {
           if (uri=~"sip:voicemail\+") {
              log(1,"BYE for SEMS voicemail+");
              if (!t_lookup_request()) {log(1,"ROUTE_0: force new
transaction"); t_newtran();};
              if(!vm("/tmp/am_fifo","bye")){
                 log(1,"could not contact voicemail");
                 t_reply("500","could not contact voicemail");
               };
              break;
           } else {
              log(1,"BYE request for UAC");
              end_media_session();
           };
        };

When receive a BYE from my PSTN gateway the Request-URI look like "BYE
sip:voicemail+ecolombo at 172.16.200.54:5060 SIP/2.0"

Thanks again
Ezequiel Colombo
