[Asterisk-Users] GSM gateway flooded cell - how to detect?

Thanks for the replies, good suggestions. What I've decided to to instead is
to modify my AGI that I use to detect the number of avaliable channels on
the gateway to artifically report a full gateway back to Asterisk from 9:30
AM to 10:30 AM and from 2:30 PM to 3:30 PM. It's not elegant, but it will
solve the problem from my user's perspective.
