Hi, hope someone can help out.
We developed a problem with our 7940 IP Phones. We're on CUCM 6.1.2.1000-13. Recently when our users who use extension mobility log on/off the phone resets and then complains that the TFTP file cannot be found.
We have 6 servers (2 per site) in our cluster and if we change the TFTP option in DHCP to another site it seems to work. We also did a "show active version" on the CLI and found that there wasn't a .cop file for the 7940's. I added one recently and it seemed to spring back to life.
However it's happening again, and changing the DHCP option is no longer working.
Any ideas?
