Hello,<br><br>I'm a new Freeswitch user. After some reading I put Freeswitch (Version 1.0.4) to work as Session Border Controller. I have only one problem that I dont know how to solve it ( or which parameter to set) and I'd appreciate if someone could give me a clue about this. <br><br>Kamailio is sitting behind FS and it selects the route or routes in case of failure (serial forking) . Freeswitch is configured to use directly the Request-URI sent by Kamailio.<br><br>So, when the 1st route fails, Kamailio receives the Reply from FS and sends back the ACK to end the transaction. More than 1 second later, a new INVITE from Kamailio with the next route is tried (With the To-header's tag is empty. Same Callid, From and Cseq header but different VIA-header's branch parameter) and FS is answering back 482 Merged Request. It happens the same for the 3rd route.<br><br>It seems that the transaction is still 'alive' in FS even if the ACK was received ?<br><br><br>Thanks,<br><br>Humberto<br><br><br>===1st route===<br><br>U 2009/09/03 17:20:36.069147 kamailio -> freeswitch<br>INVITE sip:5145555555@gw1 SIP/2.0.<br>Via: SIP/2.0/UDP kamailio;branch=z9hG4bKa0fa.0cd8784.0<br>Call-ID: 1<br><br>U 2009/09/03 17:20:36.169147 freeswitch -> gw1<br>INVITE sip:5145555555@gw1 SIP/2.0.<br>Call-ID: 2<br><br>U 2009/09/03 17:20:36.170158 gw1 -> freeswitch<br>SIP/2.0 100 Trying.<br>Call-ID: 2<br><br>U 2009/09/03 17:20:36.190457 gw1 -> freeswitch<br>SIP/2.0 503 Service Unavailable.<br>Call-ID: 2<br><br>U 2009/09/03 17:20:36.193296 freeswitch -> gw1<br>ACK sip:5142776756@gw1 SIP/2.0.<br>Call-ID: 2<br><br>U 2009/09/03 17:20:36.227492 freeswitch -> kamailio<br>SIP/2.0 503 Service Unavailable.<br>Via: SIP/2.0/UDP kamailio;branch=z9hG4bKa0fa.0cd8784.0<br>Call-ID: 1<br><br>U 2009/09/03 17:20:36.228122 kamailio -> freeswitch<br>ACK sip:5145555555@gw1 SIP/2.0.<br>Via: SIP/2.0/UDP kamailio;branch=z9hG4bKa0fa.0cd8784.0<br>Call-ID: 1<br><br><br>===2nd route===<br>U 2009/09/03 17:20:37.596885 kamailio -> freeswitch<br>INVITE sip:15145555555@gw2:5061 SIP/2.0<br>Via: SIP/2.0/UDP kamailio;branch=z9hG4bKa0fa.0cd8784.1<br>Call-ID: 1<br><br>U 2009/09/03 17:20:37.597590 freeswitch -> kamailio<br>SIP/2.0 482 Request merged.<br>Via: SIP/2.0/UDP kamailio;branch=z9hG4bKa0fa.0cd8784.1<br>Call-ID: 1<br><br>U 2009/09/03 17:20:37.598163 kamailio -> freeswitch<br>ACK sip:15145555555@gw2:5061 SIP/2.0.<br>Via: SIP/2.0/UDP kamailio;branch=z9hG4bKa0fa.0cd8784.1<br>Call-ID: 1<br><br><br>===3rd route===<br>U 2009/09/03 17:20:37.642098 kamailio -> freeswitch<br>INVITE sip:5145555555@gw3 SIP/2.0<br>Via: SIP/2.0/UDP kamailio;branch=z9hG4bKa0fa.0cd8784.2<br>Call-ID: 1<br><br>U 2009/09/03 17:20:37.642634 freeswitch -> kamailio<br>SIP/2.0 482 Request merged.<br>Via: SIP/2.0/UDP kamailio;branch=z9hG4bKa0fa.0cd8784.2<br>Call-ID: 1<br><br>U 2009/09/03 17:20:37.643139 kamailio -> freeswitch<br>ACK sip:5145555555@gw3 SIP/2.0.<br>Via: SIP/2.0/UDP kamailio;branch=z9hG4bKa0fa.0cd8784.2<br>Call-ID: 1<br><br><br /><hr />Faster Hotmail access now on the new <a href='http://go.microsoft.com/?linkid=9677399' target='_new'>MSN homepage.</a></body>
