[OpenSIPS-Users] Load Balancer module for REGISTER as well as INVITE?

[Bogdan-Andrei Iancu]

Your script has a bit of a brutal approach on the routing :) , also it 
seems to contain really old syntax or functions - in current versions 
things can be done in a much simpler way ;).

See my previous email.
