Re: H.323 problem

Are you sure that you correctly configured this gateway on CCM (CSS for example).

New Member

Re: H.323 problem

Yes, I have the right CCS on the gateway, can someone please look at the debug and tell me why the call is failing.

Thanks

New Member

Re: H.323 problem

The Debug show me you have the wrong switch type on your gateway or the CCM gateway config.check your switch type

Re: H.323 problem

we are able to make calls outbound, the problem is only inbound.

Thanks,

Re: H.323 problem

I would suggest adding "codec g711ulaw" under the dial-peer, or build a codec class and apply it. By default the GW selects G729, and perhaps your endpoint does not negotiate the correct codec.

Re: H.323 problem

I agree, define a voice class codec and voice class h323, and apply them to the voip dial-peers. You also may want to configure the progress indicators. Do you hear any ring back or does it go directly to fast-busy? You can also do a debug on the dial-peer to see which one it matches. Hope this helps!

Re: H.323 problem

According the trace voice gateway after getting the call from PSTN is trying to place the call back to the PSTN - look to the second SETUP message. He gets of course release complete.

Please provide us all dial-peers that are configured on a voice gateway. It seems to me that it could be call routing issue on this gateway.

Re: H.323 problem

Hi parwal

>>> paste ur gateway configuration

>>> make sure the CSS that u have in the gateway configuration page contains the partition of Phone.

>>> another thing if you have any FXS port on this gateway call from that phone to ur 8900 extension...

what about ur MGCP issue is it still goin on ..

Re: H.323 problem

forgot to mention check in the CCM traces whether this call is coming into callmanaager or not

>> another thing verify whether you have any overlapping extension like 8xxx or 89xx in ur configuration...
