[cisco-voip] ISDN overlap receiving digits: feh!

[Robert Kulagowski]

Thanks to our telco friends in Europe, I'm learning more than I ever 
wanted to know about variable-length dial plans, overlap receiving and 
dribbling in the called number one ISDN message at a time rather than 
all at once.

The Cisco doc on how to handle this 
(http://www.cisco.com/warp/public/788/signalling/isdn_overlap_prob.pdf) 
gives a solution, but it appears to have opened us up to toll-fraud.

Is anyone doing something like a TCL script to capture the inbound 
digits from the telco, build the dialed-number string, evaluate it for 
correctness and then pass it along?  It seems like TCL (or my dream 
PERS: BASIC.  If billg could do it on an Altair, then...) gives me the 
string manipulation routines that are a little more flexible then the 15 
rules available in a voice translation stuff.

None of the sample TCL scripts on the Cisco developer website seem 
oriented to this, and in looking over the developer docs I'm not sure 
that I can have the TCL script do what I want in the first place.
