[SR-Users] Issue with Asterisk interconnection for VoiceMail

[Igor Potjevlesch]

Hello,

 

I experienced a strange issue with some of VoIP accounts.

 

When the INVITE comes into MANAGE_FAILURE, after timeout, the config
identifies, with "dialplan", the right Asterisk instance that should handle
the call for voicemail. 

 

This part is okay, and results in a new INVITE with the Request-URI formed
with the right domain (eg. sip: <sip:%3cNUMBER%3e at asterisk3>
<NUMBER>@asterisk3). Then, the request goes to RELAY. Here is the issue:
sometimes, the request is forwarded to the IP of the UA (the one initially
contacted) instead of the IP of Asterisk.

 

I can't figure out the difference between a succeeded call and a failed one.

 

If someone has an idea. Here is the config that handles the VoiceMail:

 

failure_route[MANAGE_FAILURE] {

[.]

if (isflagset(24)) {

                        $avp(s:inv_timeout) = "5";

                        t_set_fr($avp(s:inv_timeout)*1000);

                        if
(avp_db_load("$to/username","$avp(s:vm_uri)/usr_vm")) {

                                   resetflag(24);

                                   avp_pushto("$ruri","$avp(s:vm_uri)");

                                   # Dynamic routing

                                   if
(avp_db_load("$ruri/username","$avp(s:client)/usr_fai")) {

                                               if
(dp_translate("2","$avp(s:client)/$avp(s:dest)") == 1) {

                                                           $ru = "sip:" +
$rU + "@" + $avp(s:dest);

                                               } else {

                                                           # Load default

                                                           $avp(s:client) =
"DEFAULT_VM";

 
dp_translate("2","$avp(s:client)/$avp(s:dest)");

                                                           $ru = "sip:" +
$rU + "@" + $avp(s:dest);

                                               };

                                   } else {

                                               # Load default voicemail

                                               $avp(s:client) =
"DEFAULT_VM";

 
dp_translate("2","$avp(s:client)/$avp(s:dest)");

                                               $ru = "sip:" + $rU + "@" +
$avp(s:dest);

                                   }

                        } else {

                                   xlog("L_WARN","time=[$Tf] call id=[$ci]

                        };

                        

                        prefix("710");
