As Steve pointed out, you'll need to configure ISA to allow H.323 traffic through it. ISA includes an H.323 Application filter to handle outbound calls, but inbound calls require the H.323 Gatekeeper. If you have an ISA 2000 CD, you can install it from there. I have a link to a good H.323 setup doc at http://isatools.org... ------------------------------------------------------- Jim Harrison MCP(NT4, W2K), A+, Network+, PCG http://isaserver.org/Jim_Harrison/ <http://isaserver.org/Jim_Harrison/> http://isatools.org <http://isatools.org/> Read the help / books / articles! ------------------------------------------------------- ________________________________ From: Barbara Causey [mailto:barbara@xxxxxxxxxxxxx] Sent: Tuesday, April 12, 2005 05:59 To: [ISAserver.org Discussion List] Subject: [isalist] RE: Tandberg Video Conferencing thru ISA help http://www.ISAserver.org I was told to open ports 1719, 1720, 5555-5560, and UDP 2326-2373. ----- Original Message ----- From: Jim Harrison <mailto:Jim@xxxxxxxxxxxx> To: [ISAserver.org Discussion List] <mailto:isalist@xxxxxxxxxxxxx> Sent: Monday, April 11, 2005 11:41 AM Subject: [isalist] RE: Tandberg Video Conferencing thru ISA help http://www.ISAserver.org Do you know what ports, what direction under what circumstances? ------------------------------------------------------- Jim Harrison MCP(NT4, W2K), A+, Network+, PCG http://isaserver.org/Jim_Harrison/ <http://isaserver.org/Jim_Harrison/> http://isatools.org <http://isatools.org> Read the help / books / articles! ------------------------------------------------------- ________________________________ From: Barbara Causey [mailto:barbara@xxxxxxxxxxxxx] Sent: Monday, April 11, 2005 08:37 To: [ISAserver.org Discussion List] Subject: [isalist] Tandberg Video Conferencing thru ISA help http://www.ISAserver.org Hello ISA list, We are using ISA 2000 on Windows 2000 and are trying to setup a Tandberg Video Conferencing unit.
