Hi All, Just installed 3CX 8.0.10824.716 on Server 2003 SP2 but cannot get port 5060 udp to open (5060 tcp works). I have uninstalled all virus/firewall software and windows firewall is turned off. This is a fresh install of Server 2003 and the only other software running is an email server(Icewarp). I scanned the port using Netinfo from both within the server and from an external system located on the same LAN. Thanks.
