SIP gateway

[ouhakheme]

Is it possible to configure a gateway to talk with a SIP call-agent? If so, how?

Thanks,

Yes, you can do it in different ways.

If SIP call-agent (Proxy server) uses authentication follow this doc:

Or you can directly use dial-peers using sip protocol.

Use this hidden command to register lines

credentials username <> password <> realm under sip-ua in config mode.

Hello, I have a cisco 2651 with ccme 3.3 and I want to route my external calls PSTN through my SIP provider.

parameters form provider are:

sip.provider.com

login and password port 5060

I have configured this in the sip-ua but I have problems.

All of the IP phones I have behond the router try to authenticate.

I only want 1 authentication from the router

Then i need to tell the internal extensions when they have to go to the PSTN via the SIP provider.

Please can you help me? Is there any example?
