[OpenSIPS-Users] openSIPS vs Kamailio vs SIP-Router

[David J.]

Nick,

All are used; SIP-Router is really just kamailio; But in terms of 
OpenSIP's vs Kamailio they are virtually the same software.

As far as performance goes; I think they are about even. You will notice 
some differences for example OpenSIPs has a B2B module that you wont 
find in Kamailio; that is used for certain scenarios like topology 
hiding; if that is important to you then that maybe a reason to go with 
opensips.

They both support common DB access like mysql, postgres.

Each installation has their own criteria, but in terms of scale, both 
projects are used in carrier grade deployments. And in some cases both 
are used for various reasons in the same network.

Hope that helps answer some of your questions.
