I've got a 5550 that for reasons that are unknown completely just decides to stop ringing at times. It may work for hours or days, then suddenly stop. The calls are still presented to the queue and the operator can answer them, but the keypad itself just doesn't ring.
Rebooting the keypad or the PC may or may not fix things. Generally it doesn't fix it.
One fix was to unplug the headset then reboot the keypad, another was to push the mute key on the keypad. One fix might work once, but not the next time, and it might fix it for an hour, two, half a day, or even a day, but nothing permanent.
When it stops ringing it can just happen out of the blue. One call can come in it rings and is answered and then the next doesn't ring. No reason it seems.
The system is running mcd 6 sp1, various versions of 5550 software has been tried.
PC and console are on separate vlan's (and seperate cables) with routing in between, and nothing stopping traffic either way. PC has had AV disabled, firewall disabled, java updated, etc, all to rule things out.
Anyone seen anything similar before?
