Hybrid ports blocked by spanning tree every 2.5 hours

What does the Cisco phone config look like?

[Vince-Whirlwind]

Don't forget that a Cisco phone is normally patched to a Cisco switchport configured like,

interface g1/0/1

   switchport mode access

   switchport access vlan 10

   switchport voice vlan 20

Whereas your switch config looks more like a Cisco switchport configured like this:

interface g1/0/1

   sw mo trunk

   sw tr en do

   sw tr native vlan 10

   sw tr vlan allow 10,20

If I were in your shoes, and if I had time, I would use this as an opportunity to test two things:

1/ Enabling LLDP on the Cisco phone, and getting the voice vlan to advertise itself to the phone

2/ Enabling CDP on the Procurve switch, and ditto.
