[OpenSIPS-Users] Blocking Premium and Special Routes

[Vlad Paiu]

Hello,

This will most likely perform better than any other solution - since 
every prefix is fully cached and also drouting stores all the prefixes 
in a trie, so the search doesn't depend on the overall number of blocked 
prefixes.

By default do_routing() will do longest prefix matching. For your case, 
since you're not doing routing, you should use the 'C' flag, just for 
checking the prefix.
If you want to do exact number lookup, look at the 'L' flag.
