3CX 6 working with PBX but not 3CX12.5

[ehnhuus]

Hello,
I want to use 3CX 12.5 with my Yeastar My pbx but i i cannot get it to register.
The weird thing is if i put the same settings in 3CX 6 it works fine.

3cx 12.5 is a server. You can do peer trunking with another server.

Perhaps you mean 3cx Phone for Windows 12.x is not working. This is for 3cx 12.x only and not other Voip systems.
