We took over management of a CME based call system - I am pretty new to managing CME, and this appears to be a very old version of CME (3.3). The client has purchased a 6000IP Polycom phone, which, after much searching, I am finding is basically a 3rd party SIP phone to CME. They have a PRI coming in, with several existing Cisco phones registered using CME; but what I am reading, I have to setup the router to handle phone registration for this Polycom as a SIP phone. Any guidance would be appreciated.
I have reviewed the following links, and they seem to indicate the necessary config additions:

My main concern is applying this configuration and having it effect the current phones in service. They don't have a "voice register" section in their config - they have a "telephony-service" section which seems to specify ephone parameters for the currently configured devices. Instead of the voice registers, they have ephone-dn's and ephone configs. Hope this is making sense to somebody with more expertise than me :)
