[SR-Users] DROUTING nub question

Hello,

one solution is doing following trick:

- get the length of the dialed number via transformation and prefix it 
to the number

$rU = $(rU{s.len}) + $rU;

- in drouting keep rules only for prefixes  2, 4, 6, 7 and 8
- for drouting gateways set strip to 1, so the first digit (the length) 
is removed before forwarding

Cheers,
Daniel
