3CX trunk with CME

[iramku]

Hello All,

I am currently trying to create a sip trunk between Call Manager Express and 3CX Phone System.
I have setup the dial-peer in CME, and the trunk without authentication and an outbound rule in 3CX.
When i try to make a call from CME to 3CX or on the other way i get a message 488:Unsupported media type.
I think it is a codex issue. ( I have experienced the same problem when i tried to register 3CX softphone to CME, this problem was fixed by changing the codex to g711ulaw). Does anyone have any configuration template for this?

Thanks in advance,
Ibrahim

I managed to send calls from CME to 3CX. Any idea for 3CX->CME?

Do you have the logs from the failed call from 3cx to cme? G711 Ulaw should work.
