I have enabled extension mobility.
I understand that the service is configured properly as some users are able to login/logout successfully and when I check the URL in the settings of their IP Phones it displays the IP address of the server.
For some users, when I press the service button it displays message "Host Not Found" and when I check the URL in the settings of their IP Phones it does not display the address of the server.
I have already tried the common mentioned solutions but no luck.
1. I have already made changes in Enterprise settings and replaced the CCM Hostname with IP Address.
2. I have added an entry in DNS server
3. Re-configured the service
4. Restarted the IP Phones, services [TFTP, Extension Mobility]
5. Rebooted the server
The only thing I missed out on was changing the hostname to IP address.
When i go to System---Server ---Find --- it displays the hostname. I am afraid of loosing service if I change from Hostname to IP. The application itself warns from doing the same. I am managing the server remotely and have no technical assistance at the site.
Appreciate guidelines from all you techies out there.
Looks like you have a load that falls foul of the problem listed here:
Try upgrading them to an interim version of firmware as discussed in those posts, and then upgrading to 8-5-2SR1S.
This is noted in the release notes for that firmware:
