		Open H.323 PSTN Gateway Sample Code
		-----------------------------------


This is a very simple PSTN to H.323 gateway program using the OpenH323
library. It allows H.323 clients to make outgoing calls, and incoming
calls to be routed to a specific H.323 client.

To make an outgoing call, you must have a client that supports PSTN
gateways. The OpenH323 voxilla and OpenPhone clients work, and NetMeeting
should work though only using G.711.

Some support for other clients is provided. If a H.323 client calls the
gateway with no gateway information, and the -d option was used then that
number is automatically called.



Usage : pstngw [options] [ line1client ] [ line2client ... ]
