Hello All
I am also start to integrate Kamailio IMS with PSTN, may I know my
understanding below is correct or not?
1. Inbound calls need to point to the I-CSCF
2. Outbound gateways are defined in Dispatcher on the Serving-CSCF
Also, what configuration should I change to support the above configuration?
any help is appreciated.
