[OpenSIPS-Users] dispatcher problem

[Razvan Crainea]

Hi, Matt!

So for different hashed strings like:

DBG:dispatcher:ds_hash_pvar: Hashing "061002"!

you always get the same output:

DBG:dispatcher:ds_select_dst: alg hash [1], id [1]


Also, are you assigning different weights for any of the Asterisk?
