Yet another bug with Cisco CallManager 6.0. Sigh. This was identified in version UCOS_ES_6.0.1.3103-1.
We found similarly to a previous post that when we tried to dial out, we got the following debug with "Bearer/channel not available". However we found in that this instance, changing the CLID made no difference, we verified that the customer had specified the correct number of B channels on their PRI, and attempts to use commands such as "bchan-order ascending" made no difference.

As it turned out, we were using 7945 and 7965 phones (Which id never seen before, though are worth the money over a 7961 etc!). Turning off G.722 Wideband codec on the phone fixed the problem! You may wish to think about changing the Enterprise parameter and resetting all phones if you aren't going to use this codec in your enterprise.

Wow. Thanks for blogging this. We had the same symptoms with our 7962 phones, but once we disabled advertise g.722 codec, the outbound calls on our PRI started working!
Awesome matey, glad to hear it got you sorted!
Mike.
Same issue here... it can also be solved with the following dial-peer if you don't want to disable g722:
dial-peer voice 1 voip
incoming called-number .
codec g711alaw
