Correction:
UC520 is supported by TAC.

UC540/560 only requires a simple inexpensive 3 year contract for 24/7 support.

The new CCA for UC is about to be released as 3.0.
The new software release is out now.

As of January 3rd....UC540/560 will be supported via CCA only for installs after Jan 3, 2011.

The UC is a great product if you learn it.

I like the enterprise CUCM much better as most people would.
For what you get for the money...the UC cant be beat.

I like the UC540 as it has wireless built in.
Just bought one for the house so I can have multiple SSID's for DATA. Im thinking about the camera install so I can have the image show up in the display of my phone. Pretty cool.

Opinions vary on the product but I think it is really good.

I havent forgot about my old girlfriends.
Toshiba, Comdial, Avaya, Nortel, Norstar.

I still love them with all my heart but I have a new love that has captured my imagination much the way they did in the beginning.

Cisco is her name.

Think I need help? :-)
