Hi
We have a problem with our 3905 IP Phones. When we try to change configuration. The phone move to rejected status and couldn't register to our CUCM 12.5
I found many many tftp timeout on the phone log web page
When I do capture on the phone port, I didn't find any tftp request into the CUCM going out from the phone
I try to reset the CUCM . and try factory reset the phone with no luck
What could be the issue
Thanks
Haitham
