Hi I had a similar issue with the Avaya IP Softphones, with remote VPN users trying to call each other.....
It wasn't a Firewall issue, but a codec/ network region issue on the phone system. We had to make sure the the checkpoint office mode, ip range had access to the network region with the correct codec.

I'm not very knowleageble of routing protocols and such, but as far as I know, those work as muticasts or broadcasts which I believe will not be passed through that remote access VPN. So I would really appreciate any inputs on this subject, hopefully somebody has had some experience with a similar deployment in the past and can help me out with a few pointers. In case it is of help, this is an R60 HFA06 two gateway cluster (HA, not LS), managed by a Smartcenter in the same version , everything running on SPLAT.
