I con’t make Asterisk running behind MS ISA Server so I have decided to try it with IPCop.
On IPCop 1.4.6 I have setup green and red interface. When I call from *1 on green interface to *2 on red interface nothing hapends. Pockets don’t go thrue IPCop.
When I call from *2 on red interface to *1 on green interface evrything works (I have setup port forwarding).
When I have established a call from red interface to green interface, afther that I can call from green interface to red, but only for couple of minutes (until connection is up), afther that I can’t again make call from asterisk1 on gree to asterisk2 on red.
Can anybody help me?
What Firewalls do you use? It seams to me that Asterisk can’t work behind any of them… ((
