I have a H.323 Gateway with a fax machine connected to a fxs card. I can
receive calls, but have problem with the outbound calls, if the destination
number is with Telstra, the call can get through. but for other destination
numbers, the call failed.
I did turn on the "debug isdn q931" on the router

Mar 28 22:25:14.911 AEST: ISDN Se0/1/0:15 Q931: Applying typeplan for
sw-type 0x12 is 0x0 0x1, C

alled num 0400081990

*Mar 28 22:25:14.911 AEST: ISDN Se0/1/0:15 Q931: TX -> SETUP pd = 8  callref

        Sending Complete

                Transfer Mode = Circuit

                Transfer Rate = 64 kbit/s

        Channel ID i = 0xA9838A

                Exclusive, Channel 10

        Called Party Number i = 0x81, '0400081990'

*Mar 28 22:25:16.910 AEST: ISDN Se0/1/0:15 Q931: RX <- DISCONNECT pd =

        Cause i = 0x83C5 - Requested facility not implemented
