I have had several users across our network experience a random network drop on our UCM6510 phone system, including myself. There doesn’t seem to be any real pattern to this, although there are several users that have this happen more often and some none at all. I personally did not set up this network nor phone system and I am fairly certain that the firmware is not up to the latest version. These phones are using PoE and do not lose power during the incident, just the network. The network goes down with a spinning loader on the screen for a few moments until a connection is re-established. At first we thought this was isolated to a specific user, but have found this is not the case. I have made some attempts to troubleshoot this through cabling and devices with no avail. There are only network drops with the phones and not our computers. If anyone has any ideas please help me out! I have a pretty good feeling updating the firmware could help resolve this, but my manager is not quite as confidant with that being the issue.
