Re: [SR-Users] disparcher making loop with call

Hello,

You’re only pasting the dispatcher route.

You need to follow the script logic. An invite comes in, how does it know the call is coming from the client and has to be sent to freeSWITCH? Conversely, how does it know it’s coming from freeswitch?

Probably using the permissions module with https://kamailio.org/docs/modules/3.1.x/modules_k/permissions.html#id2528655

You can check if the $si is the freeswitch, then send to clientB

Hello,

there is something wrong in your config file, failing to detect the traffic from freeswitch. Load debugger module and enable cfgtrace logging, then see what actions are executed in the configuration file, maybe you can spot what goes wrong there.

Otherwise, to get more help from the mailing lists, the full config is needed.

hi i m using kamailio 5.3 as register server and using dispatcher i m dendign the calls to freeswitch ..

but the issue is then freeswitch send back call to kamailio after processing media ... it should go back to client but it again send call to freeswitch ,, which create the loop and hangup the call with (Temporarily Unavailable (code: 480))

*what i want *client1------>Kamailio------>FS-----Kamailio----->Client2

*but I am getting this * client1------>Kamailio------>FS-----Kamailio----->FS----->kamailio----->FS
