Has anybody used the Grandstream DP750 base with the DP720 handset on the 9100?
I cannot seem to get it to register. I left the SIP registrar port default at 5070 and assigned a personal index in 15-05-27 and entered a user ID and password in 84-22 but the unit will not register.
I have one NEC IP phone and it came up without issue and I have two 5111 licenses, one active, one available. Not sure where I am going wrong.
