Problems with gateway h323

Unanswered Question
May 13th, 2009

Hi all,

We have a problem with the configuration of h323 gateway. This gateway is a Cisco 1861 with 4 FXO.

The calls what enter in fxo port, the phone rings but cannot established call.

The command "show call history voice brief" display this error "no resource (47)".

I have attached two files with "debug voice ccapi all", "show running-config" and "show call history voice brief"

Any idea? Where is the problem?

Did you check to see if the partition of ext 2999 is in the gateway's calling search space?

Hope this helped, if so please rate.

Where the call is going? CM or ?

Seem like it fails in there, you can see more with debug cch323.

Thanks for your fast replys.

The call go to CUCM (version 6.1). The gateway is configured with a CSS that contain the partition of phone. The phone sounds when the call enters, when off-hook the call is droped.

With gateway in mode MGCP works fine, (but don't have calling number in display of phone). In mode SRST also works fine. In mode H323 fails

I have attached the "debug cch323 all". I tagged in the debug in the moment of drop of call ("Off-hook").

Thanks a lot
