Cisco 8865 on RingCentral?

[Ernest Mac]

I would normally suggest getting a Cisco 8865 3PCC phone to be installed on RingCentral but RingCentral is telling my customer that it doesn't have to be 3PCC, they say we need to check to see if the phone is configured to allow web connections and it needs to be unlocked.  Has anyone ever heard of this or is RingCentral just making this up?

Thanks in advanced.

Their site says otherwise, and has wrong information as well.

A 3PCC/MPP device is NOT supported with any Cisco call control and it will not register. And they don't just automagically switch between 3PCC and enterprise (or viceversa) as their site seems to imply. And now you can perform that switch, but it requires a license for that to happen.

A phone with enterprise FW WILL register to CUCM and it * can * register with other 3rd party PBXs, assuming someone wants to go through the trouble of manually formatting and configuring all the required fields in the .xml files the phone would get from CUCM to work.

Bottomline, you need 3PCC/MPP devices if you plan to use them with NON-Cisco call control.
