IP-VPN/VoIP

[Irwin Lazar <ILazar () tbg com>]

I'm curious to see what folks are doing to support VoIP across encrypted
IP-VPNs.  From our understanding, very few firewalls can statefully manage
the random port selection during an H.323 call setup, so the only way to
support VoIP across a firewall is to open up a range of ports.  For obvious
reasons, this isn't something I feel comfortable recommending.

Has anyone run across this issue and if so, how did you address it?
