The problem is the "dialer fast-idle 5" command in you config, please remove this and the problem should be resolved. For more info on this command please look at the following url:

I have removed the dialer 'fast-idle 5' and I am still having the same problem.

Maybe you should restrict the interesting traffic that is allowed to bring up the line, at the moment you are letting any IP traffic bring it up. It might be more sensible to use an access-list to define a tighter set of traffic patterns that you want to bring the line up. To see what traffic is bringing the line up you can use the following debug:

debug dialer

Also it might be an idea to lower the increase the threhold to limit when the second B channel is bought up.
