IP Phone Couldn't register with Call manager

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
