John,
Thanks for the info.  I'll leave the code commented out in the dialplan.
If I put in the NAT SIP patch then will reenable it.  Is an interesting
concept for some long snowy night reading!

BTW... regarding the sound directories.  I didn't come up with any
solutions that haven't already been discussed here.  Thanks again for your
work.

Robert
