there is a customer who is little tight in budget. they have polycom 450, 550, and 330 IP phone. They like to purchase UC520. I am wondering if those phones are compatible with UC520, or if there is any documentation to have UC520 compatibility.
Cisco says that they only support cisco phones and if something doesn;t work with third-party, you're on your own.
This said, basic calls will certainly work, thing is all the features will be awkward to activate, and some won't work at all, at the end of the day it without cisco phones comes out quite a poor system and likely custome unsatisfied.
