Re: Netmeeting problems when calling via PSTN

Take a look at this document on Outbound ISDN Calls Fail when Originated from NetMeeting or Similar Third Party H.323 Devices. Should be of help.

Re: Netmeeting problems when calling via PSTN

Hi,

use

Bearer capability speech

on the voice-port of the outgoing ISDN-Line.

Under some circumstances the router doesn´t know that the netmeeting-call is voice and so it cannot connect to a voice-device outside.

I cannot better disclaim, try if it works.
