Hi all, hope everyone is well !!!
I am using 3750 switches at the wiring closet and I sometimes lost power to the wiring closet and the switch got rebooted. But somehow not all the phones come up after the switch reboot and back online. Some phones got stuck in "Configuring IP" and even if I manually power cycle the phone it still won't come up. It seems like it couldn't see the voice vlan after the reboot and the only way for me to bring it back online is to put the switchport in the voice vlan, see my switchport config below.
interface FastEthernet1/0/2
switchport mode access
switchport voice vlan 40
spanning-tree portfast
spanning-tree guard root
switchport access vlan 40 - I had to add this command for the phone to come up and once it's up then I can remove the command.
has anyone ran into this issue ?
Thanks in advance for any inputs / suggestions !!! I am running CUCM 7.1.3 with phone load release P00308010200

Check IOS version on switches as you may need an update.

I would recommend 12.2.55-SE5
And a good review of VTP status just in case.
Thanks for the nice rating and good luck!

Thanks Paolo !! VTP looks fine and I am running the same IOS release at all locations but somehow I sometimes run into this issue only at this one location. The issue seems to be isolated to this one location.

There are cases where a bug nastly appears in a single place but not in others
I recommend you update the switch, pull and replace the plug for a test, then let us know how it goes.

Thanks Paolo !!!
