i have a question sorry i still beginner in VOIP network,
if we use SIP at 2 gateway and each gateway will connect with ip phone (SSCP) what will happen or what is the procedure that will happen to make call ?
Works like this:
IP phone will talk SCCP to CUCM, and gateway will talk SIP to CUCM. When a call wants to be placed, the gateway or the phone will talk to CUCM. When they agree on the phone call and audio is ready, the audio will be passed directly between the endpoints.
If you want more information than that, you're going to have to be much more specific in what you're looking for.
