Dear 3CX Community, We are switching from asterisk to a windows friendly PBX and I was surprised to see something so slick as 3CX running on Windows. It took some time to get fully familiar with but the results are nice. Unfortunately I have been making 12+ hour days here at the office in order to get outbound working with 3CX. This issue is horrible and hopefully there is an anwser. My Temporary Setup: - Bell Modem/Router (routing taken over by linksys) - Linksys Router WRT54G (ports 10-50000) pointing to the Windows 2003 SP1 server & firewall off - 3CX (latest version) - 2 VOIP providers - Aastra 9133i phones Problem: - Both VoIP providers cannot be reached with outbound calls - The problem is driving me insane and I am at a point were I really started to like it.
