Hello everyone,

I’m working on freeswitch , where I have SIP calls coming from A-Party to my freeswitch and I’m routing it to B-Party.

I’m facing an issue , when I’m getting back the 183 message from the supplier(B-Party) and forwarding it to the customer(A-Party); the customer is not hearing the RBT and asking to send 180 rather than 183 . (the supplier is only sending 183 without 180).

Is it possible using kamailio to replace this 183 message with 180 message , or even add 180 message while keeping the same 183 message ?

Regards,

Ali Taher
