[OpenSIPS-Users] Load_Balancing

[Bogdan-Andrei Iancu]

Hi,

Considering the fact that Ast_2 cannot perform auth on a challenge done 
by Ast_1, you should re-consider the routing logic in OpenSIPS, and not 
to use LB, but rather dispatcher with hashing over call-id for example.

When an INVITE is sent to one of the Asterisks, we receive the "401 Unauthorized" message from that server. But when UAC sends the INVITE with the authorization, the LB-module sends it to another Asterisk. Sometimes it happens multiple times.
