TLS is a method for setting up an encrypted connection, AES is a kind of 
encryption algorithm (a cipher). So TLS can set up encrypted sessions 
with many different algorithms/ciphers, what you probably need is to 
configure your TLS settings such that the ciphers that are allowed 
include the AES cipher that the phone wants to use.

At least this should point you in the direction of what to look at. I 
can't help much more than that because I don't know a thing about 
polycom phones nor do I know where to configure the allowed ciphers, 
would take a bunch of googling to figure those out, but at least now you 
maybe know what to google ;-)
