Register Polycom IP 550 to 2 different asterisk switches

I’ll admit it i’m new
i am looking for help with registering the Polycom IP 550 phone on two different switches.


I’am not familiar with polycom, but most sip phone are able to program more than one SIP Account, maybe look for a key that has the option of being set as a Line key.

Accoording to this page, there sould be a Lines option in the menu’s


you just assign it as a second line. Much easier is you are running 4.0 firmware
