I have an issue that has stumped our vendor and apparently 3com so far. Since I don't know if this is a NBX or Switch issue I posted in the NBX area also. This is my first post on here so...
Issue:
Random phones stop working. Usually 10-20 at a time. About once a day. Displays stay on but they have no dial tone and are affectively dissconnected from the NBX. The NBX NetSet shows the Telephone status of Unknown for affected phones.
Steps taken:
Work around is to unplug and plug in the phone.
But eventually it occurs again.
No errors in status of phones, in NetSet, Nothing found in monitoring of 3com supervisor.
We had an issue of loosing audio and disconnections from the network. (pc's hooked up to back of phones). We RMA one 4500 switch, replaced two non-3com switches for total of 3 4500 switches. Configured as a stack but not resiliant as one of the gigports has to hook up to another switch.
All configurations performed by a 3com goldpartner on serveral occasions.
