Polycom 650 Multiple Servers on the same VOIP phone

[Anonymous]

I'm using a Polycom 650 with the lastest bootrom and all. 

As you are aware there are 6 buttons on the 650 Polycom.

I currently have extension 700 on server 1 -> with 1 call per line and 4 appearances. (Uses up buttons 1 thru 4)

I would like to setup extension 701 on server 2 -> with 1 call per line and 2 appearances. (Use up button 5 thru 6).

How is that possible ? And is it even possible.

I've tried Cisco, Avaya, Snom, Grandstream, Panasonic, Digium and it's possible with all those phones but now we have decided to go with Polycom and I'm worried since I haven't been able to accomplish that

Hello surgemorales,

as mentioned in my other reply the BootROM itself does not matter as features are either added in the SIP or UCS Software so depending on this yet unknown Software Version the advise below may be of interest to yourself.

In addition the Software Versions change over the time and someone finding this post via the search function would not know what is classed as the latest software at the time of the post.

Please check the UCS Admin Guide 4.1.0 which can be found => here <= on page 222:

Enabling Multiple Registrations 

Polycom phones can have multiple registrations; each registration requires an address, or phone number. Table 7-27:

Enabling Multiple Registrations explains the registration parameters and options. The IP 321, 331, and 335 phones support a maximum of two registrations, the IP 450 phones support up to three, the IP 550 and 560 phones support up to four, and the IP 650, VVX 500 and 1500 phones and SpectraLink handsets support up to six. Up to three SoundPoint IP Expansion Modules can be added to a single host SoundPoint IP 650 phone to increase the total number of registrations to 34. The SoundStation IP 5000 and 6000 each support a single registration.

Each registration can be mapped to one or more line keys. Note that a line key can be used for only one registration. The user can select which registration to use for outgoing calls or which to use when initiating new instant message dialogs. Note that this feature is one of several features associated with Flexible Call Appearances. For definitions of all features associated with Flexible Call Appearances, see Table 7-4: Flexible Call Appearances.
