Unanswered Question
Mar 3rd, 2010

Hi Guys,

I am trying configure Extension Mobility in the CallManager version 4.1.3 and I did all step, but, when I go select the service in IP Phone It stayed in Request for same times and don´t connect and It return to option "Make Your Selection" in a one IP Phone 7940, another IP Phone 7940 appear the message "Host Not Found" and the another IP Phone 7912 appear the "Failed Connected". The IP Phone are registered by DHCP that is configured in Gateway 2801. I Did the review configuration in Cisco CallManager and didn´t found the wrong configuration.

Any Suggestion to solve this problem?

Is the URL you set on the IP Phone Service using a host name or IP address?

If it is host name, then you need to ensure that your IP phones have DNS servers assigned, and that the DNS servers have the  host name in them.

Typically on CM4 you would use the publisher's IP address.

Hi Wilson,

Can you check Phone URL Service Parameter in Enterprise Service Parameter . You

should change it to IP address instead of Publisher's Hostname Name..
