Re: Nortell IP Phone 1110 on 3CX Phone System v10.0.24018.23
Nortel phones are not in the 3CX list of supported hardware and I don't know if yours is a new or legacy model phone. I do know they USED to use a proprietary Unified Networks IP Stimulus (UNISTIM) protocol but I don't know if that is still the case since Aastra got the rights to make phones under the Nortel name, maybe somebody here will have and answer for you. If it were my system I would stick to using only 3CX supported phones, it will make your life a lot easier.
