Tcl – Tool Command Language . In the Tcl community it does NOT stand for Think C Library, as it does in the Macintosh community. Neither does it stand for “The cool language” (though it is).
Run under CISCO IOS, if I understand you want to use Quintum, If I had the extra cash for a project and I would like to get the best of the line for it I would use Cisco all the time.
If you use Quintum you need a Billing software to tell the quintum thru radius when the call has to stop.
