We have a client with a UC-520 and 20 or so 524S phones. One extension, 218, shows busy when it's not. I swapped phones with a new one and it still happens. I have attached a debug log I created but I cannot see anything odd about this one phone.It's...

This wasn't a problem at this site when we set it up but now every call has a 20 second delay before it begins to ring. Looked at a debug and saw out of sequence packets and packet queue overflow but I am not sure if this is the issue. Whatcan I test...

We were not able to set up our UC 520 firewall with CCA to allow port forwarding to a couple of network storage servers and had to use CLI. Now I find that I need to open several ports to test VPN connection kits for a few client networks and even if...

Our UC 520 lost power. When power was restored, we were unable to connect to it. Our phones and internet are down. Does anyone know of a way to restart a UC 520 successfully?

Latest phone loads and IOS 12.4. This extension has had this problem for almost a year now. Have upgraded the software a couple of times. I haven't tried switching ports yet or changing extension numbers but everything else is new.

The issue is actually user authentication. I can use the same computer and create a vpn tunnel to the same destination using a different internet connection ( I "borrowed" a neighboring office's for a minute) and it works fine. From behind our UC 520...

Had to dig out from Snowpocalypse 2010 before we could get this out to you. Our system seems stable enough although we are missing some phone files. Thanks for looking at it for us.

Thanks for the response. I have attached a text showing a couple of settings that differ from yours. TAC is not a readily available option for us. We purchased our UC 520 through Cisco sales to help us sell the product (we have sold 3 this year) and ...

I have the flash utilization down to 58% by already doing that. Still get the same tftp error during the CME portion of the upgrade. We are a bit wary of playing around with this too much. Lost our entire flash contents Monday and knocked us offline ...
