IP Phone Couldn't register with Call manager

[Andrewkai]

Hello,

I'm currently running for one voice project. Gateway and call manager are up and running. I can make call out by using soft phone.

But I have a problem with IP Phone registration with my call manager.

It shows Configuration IP and nothing came out after that. Could you please help me?

Sincerely,

Andrew

Andrew,

what is the tftp server for ip phones? you should set tftp server to gateway router if your gateway is doing dhcp.

Hope this help..
