After setting up CUCM 9.1.4 on a Virtualize environment i discovered that all my 3911 phone worked properly the first time, but after unplugging and replugging the 3911 phone they the all fail to boot up...(the all end up power cycling) and finally how to i factory reset a Cisco IP phone 3911, i have tried the specified procedure on the Admin guide but still without success
Hi Mgogna, i can’t even get to the setting of configuration of the phone because whenever i plug the phone on the network it just keeps power cycling its self but when i power with just a PoE the is not present on the Network its boots up okay
I am very grateful for your support, I have tried doing just that for the past 3 days but to no success, am skeptical about the Cisco SIP 3911 phone don’t use the same proses for factory reset with other Cisco Phones, this has become a major challenge for me because I promised my customer that the 3911 would work perfectly on their new CUCM platform of version 9.1.4
I have noticed that whenever i add the voice Vlan on the switchport interface the 3911 phone starts power cycling itself, and immediately i remove the voice vlan config from the switchport it comes up normally
