Hi all, Avaya PBX ISA 2004 We have an Avaya PBX that supports VOIP. We have a softphone client that we can run on our laptops. We can connect to the call server just fine from inside the company. But if you log in from outside with VPN, the connection fails. VPN has been changed to full access to the internal network to see if it made any difference. It does not. The same laptop is being used inside and outside the company for testing. The ISA server is set as the default gateway. The windows XP firewall is turned off. Any clues as to why this would be happening? This application worked fine on ISA 2000. Ray Dzek Network Operations Supervisor Specialized Bicycles 408-782-5420
