7912 IP phone which is not registered by dhcp

Unanswered Question
Jan 9th, 2009


I have a 7912 IP phone which is not registered by dhcp. Only one time was recorded by fixed ip. I have a CCM 6.1.2.

I wonder if there is any way to fix this from the phone.

Is the only phone that does not register. The rest of the registered phone well.

Thank you

I have this problem too.

Hi Daniel,

Could you please clarify a little bit more.

Using fix ip address i assume.

What is the message you see in the IP Phone?

Mask, Default GW VLAN is correct?

Inline power?

Switch config the same?

My CM is ccm 6.1.2 with ip, mask, IP phones only need to register. It is a model of work.

IP Phones:

Assigned the IP address (with mask, but not recorded. In this case the message is setting CM list.

The other case was to work with dhcp, erasing all of the IP phone configurations, the message is configured via dhcp ip ... never recorded.

Perform the same task with different IP phones 7940 and 7960. They were successful.

Thank you!
