[Asterisk-Users] number detection problem.

Thanks for all of the suggestions.

There is no noticable static on the channels and I'm using the tor card as
primary timing source...

I'm now trying relaxdtmf and turning the gain way down. Since it's an
intermittant problem I won't know for a while.

Thanks again.
