[Freeswitch-users] 3CX-Sip-Trunk / Freeswitch cannot reach 3CX

[Thorsten Göllner]

Hi,

solved:

you have to fill out "Outbound Proxy" (same ip/domain as
Registrar/Server/ Hostname). This forces 3CX to answer on Port 5060 to
freeswitch and connection will be established. Else 3CX answers on the
wrong (not opened) port.

Best regard, Thorsten
