It is not such a dumb idea !!

I am using The ericsson tigris platform for our few remaining PRI's for
our
dialup pools. We are currently hanging asterisk off these using drop &

(both ways)... Now if we could actually get some code to get the voip
working to/from asterisk we could do away the the PRI cards....
