Hello,

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.

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.

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.

It seems that the transaction is still 'alive' in FS even if the ACK was received ?


Thanks,

Humberto
