[OpenSIPS-Users] drouting: + not allowed in rule prefix

[Bogdan-Andrei Iancu]

Hi Matt,

the DR module allows only digits for prefixes as internally it builds a 
decimal tree (data structures). Accepting also non-digits chars will 
make the tree really huge and memory consumption will not pay off.

Usually, what I do is to replace/strip the  non-digits chars before DR.

Regards,
Bogdan
