no busy tone by unknown number h323 and cucm7.1

hi,

i configured a CUCM 71 and a H323 GW to PSTN. All works fine, but when I call an unknown number I get a Ringtone, no busy tone. The number is not configured in CUCM.

The number you are calling have you ran it through Dial plan Route Plan report.You may have a translation etc that is matching it.Also is this an external or internal call?

sh dialplan number 9999602
Macro Exp.: 9999602
No match, result=1

The prefix is 9999 the destinations are 3digit Numbers, e.g. 602.

The call comes frome PSTN through H323 to CUCM 7.1.3.

The destination here- 602 -  is not configured in CUCM. But if I call this number (9999602) I hear a the ringtone. But I want to hear a busy or somewhere like "unallocated number".

If I call 9999123, where 123 is a configured destination, all works fine.

I think the CUCM give back the unallocated number to Gateway, but it forwards this not to carrier PSTN. Is there a command to force this? Or a thing to configure at CUCM?

Re: no busy tone by unknown number h323 and cucm7.1

If you look at the debug we are actually sending out an alerting message which is probably causing the issue.If you run a route plan report in callmanager for anything starting with "6" , do you get any results.

I get results. There was more than one destination beginning with "6". But no destination with "602".
