    Hi

    I'm using 3COM OfficeConnect firewall and i am not surewhat happens with ports.

    If i open all documented ports there is no sound in both directions, but if i bypass the firewall al works.

    UDP 5060-5061, 9000-9007, 5004-5005, 3478, 5482

    I know problems with firewalls are common, but really that's all ?

    Thanks in advanced

    Are you forwarding the open port to your 3cx server? If not you need to. I have all those ports open on my Cisco router and forwarding to my server and everything is working fine.

    Almost.

    Sound uses the 10000 - 20000 ports. Try open these (UDP) and it should work.

    Documentation says that you need to forward ports to/from host of 3CX PBX (in both direction, it means make "full cone NAT" for PBX ports)...
