Well, IMHO the reason is that key '#' appears in all the phones :)

I assume this is due to inheritance from common URI syntax (an username in a 
mail URI doesn't allow it also).

I think it's ok to allow it, but it would be nice if Kamailio would 
decode "%23" as "#" directly, without the need of using transformations. In 
this way, if a strict compliant phone encodes "#" as "%23" in the RURI it 
would be automatically detected by Kamailio as a "#" symbol.

Could it be feasible? Regards.
