I am wondering how can I busyout B-channels of my MGCP gateway (6608 blade). I tried to change my CallManager 3.3(4) setting (Under Service Parameter->Advanced->Change B-channel Maintenance Status) using either 1 or 2, but it didn't help (i.e., S0/DS1-0@SDA000F348E778E = 1111 1111 1111 1111 1111 2221).
Can anyone help? Btw, the 'enable status poll' on my PRI configuration is ticked off. I'm not sure if that is required.
