Hello all,

I want to know the difference between kamailio-3.1.1 and kamailio-4.0 in regard to their features. If anyone has the experience to use both. What improvements will one enjoy on upgrading to kamailio-4.0 as compared to kamailio-3.1.1. I asked this question and a friend suggested some webpages. They give updates in modules for every version from 3.1 to 4.0. That is good but I want to know in short what main improvements will I get. Thanks for help.

Cheers,
Owais
