Bogdan,

Thanks for the pointer. I've just downloaded the vm, and looked thru
the code. It's using nathelper with rtpproxy ... but rtpproxy only
support UDP. I'm using VPN from my home to my office and the firewall
doesn't allow UDP. That's why I'm thinking of using nat_travesal which
supports TCP. Any pointer to sample config with nat_travesal?

Thanks,
Jeff
