We have a UC560 here that's been running pretty rock solid for about 2 years.. just recently another site (that also has a UC560) started having issues with Intra-Office dialing with this site (via VPN). I went to SSH into the UC560 and it was refusing my connections.. yet all the phones in the office were up and fine, and people were even making calls. I waited for the calls to end, rebooted the UC560 and everything was back to normal.. or so I thought.. 2 days later, same thing started happening. I rebooted again, fixed it for a day or two.. now its occuring AGAIN.
Nothing has changed on the network, I've verfied its not a switching issue, I'm only using one port on the UC560, its not our gateway/router.. just a phone server.
Sometimes I can SSH in and do a show run and make it about 12-14 lines in then it boots me out. CCA won't work, etc...
If the phones were rebooting/having issues I'd suspect it was clearly a hardware issue on the port, but the local phones seem to be fine, just intra-office dialing, ssh and cca..
I just updated it to the latest UC560 Software Pack a few days ago to see if that would resolve it, it didn't.
Has anyone seen anything like this?
