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@172.16.200.54:5060 SIP/2.0"
Thanks again

Subject: Re: [Serusers] send BYE to SEMS
SEMS puts a special delimiter into the username of the
Contact header
field it generates. The content of the contact header field will be in
the Request-URI of BYE, so you can check if the Request-URI of BYE
contains that delimiter. If so then you can call vm, otherwise call
t_relay().
See user_prefix_separator parameter of SEMS.

Ex:
if ( BYE or CANCEL ) {
if (for established SEMS session) {
vm("/tmp/am_fifo","bye")
} else {
end_media_session();
t_relay();
};
break;
};
