I have a client with Sonicwall VPNs.  Asterisk is at head office on 
internal LAN, six external locations all have Linksys 2102 ATAs and 
Polycom IP501 phones registering and placing calls through the tunnels. It 
seems to work fine, but there is plenty of bandwidth between the offices, 
and they use G729.  I think wrapping up the UDP stream into a TCP based 
tunnel might cause havoc if there is any packet loss or delay.
