I need to busyout the b-channels on all the T1-PRI's on a WS-SVC-CMM Cat6k voice linecard. I have these configured using MGCP signaling with CCM 4.1.3sr4d


There are active calls on the T1's and I would like to busyout the channels when the call completes.


Any help is greatly appreciated.

Hi Anthony,


You can gracefully busy-out (graceful out-of-service) B-channels for troubleshooting purposes. This document discusses how to busy-out B-channels from a Cisco CallManager for Media Gateway Control Protocol (MGCP) controlled T1 or E1 voice ports.


From this excellent doc;

Hope this helps!

Rob,


Thanks for the excellent information. One additional question...


How can I see if the channel is currently active and when it gets gracefully busied?


This gateway is a Cat6500 CMM blade.
