Outgoing calls drop after 9 seconds

With ccm 3.1 and vg200 with 1 vic-2bri configured as H323 gateway (no alternatives) incoming calls work great. Outgoing calls last only 9 seconds. Aftern that vg200 drops the call.

Vic is connected to an ISDN NT box of provider.

Disconnect cause 0x29 (Temporary failure)

Any ideas?

I thing it might have to do with frequencies

Re: Outgoing calls drop after 9 seconds

Can you enable debug isdn q931 when you make an outbound call and post the output here? Also, which IOS version is being used on the VG200, and can you post the configuration also?

Soon I'post the debug isdn q931...

Debug voice ccapi inout shows disconnect cause 0x29

and debug cch323 h225 shows that vg200 places the call from h323_active to idle.

Re: Outgoing calls drop after 9 seconds

The ios was finally the problem.

The one that comes with vg200 (12.1.5xm) worked in 2 locations. At the exact location where the roll out was implemented never worked (dropped the outgoing calls after 9 secs, as well as crashed the vg200 when we were calling a specific cellular company!!)

I tryied also 12.5.1xm4, 12.1.5T9, 12.2.6 and the problem was not solved. We contact the local PTT

and these guys checked in real time the disconnection reasons (friends from the past)

So when PTT said that the call was rejected from our side I reinstalled the ccm. No good.

Finaly, beign desperate I downloaded 12.2.2T and ...

MAGIC happens because of christmas I suppose.

One Alitalias small branch office in Athens Greece is live with IP Telephony since 18 Dec 2001.

Thanks anyway.

P.S. Dam those IOS. It's not the 1st time I get in trouble with it.
