Has anyone set up a 916 to provide SIP to a 3CX phone System?

Does it work?  Any know issues?  Can you share the config?

You want to connect it as a SIP trunk or extensions?

SIP Trunk to the 3CX

Valtech,

Thanks for posting.  We have recently heard of 3CX systems being installed with Adtran units.  However, if you are setting up any two manufacturer's units to work together for the first time, we would suggest setting them up and testing in a lab environment prior to installation at a customer location.  In one installation we had some difficulty sending DTMF between them using RFC 2833 events.  I would suggest that you verify the 3CX can be set to in-band DTMF and G.711u codec, without sending the RFC 2833 packets.  Otherwise, this would be a good initial test in your lab to verify compatibility.

Thanks!
