IP Phone dials but stuck in silent state

Hi,

Can someone explain why IP Phone failed to send digits to Call Manager. I have IP Phones which cannot place a call, but can receive a call. When user dial digits, it's stuck in silent state and no ringback tone heard.

I tried to reinsert the IP Phone to the CCM but that is useless. Anyone have the same problem ? Thanks.

What I mean by silent is absolutely no tone heard, even a busy tone. It happens to all calls from the phone, not restricted to PSTN call only.
