Just curious. My company is in the process of purchasing a Mitel solution. Were currently are on an outdated CS1000 so you can see the need for an upgrade. They have task me with the controller install and etc. My question is will Polycom SoundStation IP6000 SIP phones work with Mitel? Reason i ask, Mitel wants to sell us their UC360 Audio conference phones and for what they will do (only provide audio) we figure the cost is not justifiable. Can anyone shed some light on this. Thanks in advance.
