Has anyone got experience with a Checkpoint 6xx, 7xx or 11xx firewall/router and configuring it to let 2talk SIP through?
Even with every blade turned off, the Checkpoint prevents all incoming calls to my Cisco SPA502G via the UDP protocol (they're sent to VM).
When I set the SPA to the TCP protocol, I end up with registration issues and calls connecting but no audio.
I've read in these forums and from 2talk support about disabling ALG.
But I can't figure out where and how to do this on the appliance.
Any advice or tips would be much appreciated!
Thanks heaps.
Phil
