Dialing out a Gateway with BRI gives ISDN Disconnect Cause = 0x82E4


I'm having a IOS H323 gateway configured and when I try to place a call to the PSTN using a BRI interface, I get a the following ISDN disconnect cause:

Cause i = 0x82E404 - Invalid information element contents

The bearer cap looks also wrong: 0x8090A2 (G.711 u-Law Speech) instead of 0x8090A3 (G.711 A-law). The gateway is a VG200 with IOS 12.2(13). Can anyone tell me what is going wrong?

Re: Dialing out a Gateway with BRI gives ISDN Disconnect Cause =

I Already found it myself. This is the command needed to change the bearer cap:

voice-port 1/0/0

compand-type a-law

It wil change the bearer cap from 0x8090A2 (G.711 u-Law Speech) to 0x8090A3 (G.711 A-law). The connection to PSTN is fully operational now. Thanks.
