Hello

It seems that userblacklist module doesn't support non-numberic values. 
(The only way to match via  dtrie is 10, which is numerical only). You 
can use carrierroute instead (a bit of overhead), but carrierroute has 
blacklist capabilities and can support alfa-num matching 
(http://kamailio.org/docs/modules/stable/modules/carrierroute.html#id2863179)

I will have a look on how hard is to extend dtrie to support alfa-num 
matching and get back with a reply on the list
