UC500 series questions (switch model and SIP ability)?
We are thinking of implementing a UC500. Currently we have a number of CE 500TT and TC switches. Could we use these existing switches or would a UC500 deployment require us to replace the 500's with 520 switches?
I do not see much documentation for the UC500's support of SIP trunking. Is SIP trunking supported in the UC500 and if so, where can I find documentation on how to implement it?

Hint 1: place a CME interface directly on the internet if possible at all. You will protect it with an ACL. This will eliminate all and any NAT issue that are a problem in 90% of the cases.
Hint 2: do NOT subscribe a service that require you to regiser each line individual. Thta is proven to cause trouble.
If you need multiple numbers, work with an ISP that can give you a DID block with a single registation (or no registration at all).
