Re: Question about SIP.

Hi Tito,

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.

Re: Question about SIP.

Thanks a lot Eng.Nick

But if you tell me the full configuration, it will be kind thing.....

Thanks....

Re: Question about SIP.

Tito - there are anywhere between 10 and 40 lines of configuration on the gateway and pages of configuration on CUCM.

I would start by doing a cisco.com search for 'sip gateway cucm configuration' or something similar.
