Re: [Re: [nsp] Translation Rules for India]

each city is 9n (as far as i can remember, but i haven't had to try and
do the entire country on one gateway) - i would try matching on that
and write your peers to creatively match, then you can chew up the digits
with prefixes or translation rules. (karnataka would be dialed
0119195nn... i believe, so you would only need to strip the 01191)

you could try something like this on your pots peers (i am making the
assupmtion that your are terminating on the pstn)

dial-peer voice 1 pots
dest 011919[5-n].T
prefix 9
port 0/0:d
