Dynamic Routing module is designed & used for prefix based routing and 
not for regexp based routing. The module uses internal prefix trees for 
fast prefix lookup - something like this is not possible with regexp.
It is not a limitation, it is the usage case it was built for - if you 
need regexp based ops, see the dialplan module.

only numerical prefixes are accepted . If you want to define a rule to 
match all prefixes (wildcard), simpy use a an empty string prefix.
