Hi, im new in here but i want to ask.
I have two potential clients, but they ask if they can use their phones or part of the phones they have, can i use every 3rd party phones in ucm62XX?
Is there a list of 3rd party phone compatibility with UCM62xx?
One client i think has polycomm phones(don’t know the model)
Another one has Avaya 1603 and 1608 phones.
Hopefully you can help me
