[Asterisk-Users] PSTN Gateway

Hello,
  I am looking for information on setting up digium FXO card for use as a
PSTN Gateway (H323-PSTN) to work with GNUGk.

I am basically looking for the setup and it would be great if anyone can
share his experiences with the same. Also, if there are any limitations in
going for such a setup and problems that may arise/things that I should keep
in consideration.

Thanks & Regards,
Deepak
