   OK, so the bad news is that with Vonage's VOIP service you wouldn't
need to do anything special.  If you're behind a stateful firewall the
ATA's SIP keepalive will keep the necessary hole open.
   If it's not working with Verizon's service then they must be doing
things differently, or your firewall isn't establishing states
properly.

No problem is so formidable that you can't just walk away from it.
