Read the thread.

What you want is a dial plan.  Fine, we should standardize a way to get a
dial plan for every TN.  In nearly every case, that comes from the
regulator.  There are conditions where what you get from the regulator is a
dial plan that determines the end of a "prefix" and you have to go somewhere
else to get the rest of the dial plan.  Fine, we can do that.

99% of the telephone numbers in the world have a pretty simple dial plan.
That's the case we should optimize.    

Overlapped dialing decoding is walking through a dial plan.  We should
provide the means to do that.  All of the hundreds of millions of phones you
are talking about work fine without Send-N.  They have the dial plan for the
home country burnt into the switch, and they use a time out for
international numbers.  

There is value in improving the dialing experience of everyone, but not so
much that we need make it really optimal.  You have brought us a problem I
think is worth solving: determining dial plans for international numbers.  I
don't like your solution, but I'm happy to work on the problem.
