I was talking with my contact at Yealink and I asked them what other phone vendors currently support the new Yealink T7 and T8 series phones. Here is the reply I got:
"Also, regarding other VOIP vendors that actively have these model phones supported, please see below:
Alianza/ Skyswitch/ vodia/metaswitch/3CX/Epygi/netsapiens/Yeastar"
Why is GoTo saying by the end of Q1 it will be supported. What is taking so long and why do so many other vendors have these models supported already?
