I am trying to make sip server. I Was trying to install Opensips and Freeswitch. But I have a basic question here,
What to choose Opensips or freeswitch ?
I also found that opensips is integrated with freeswitch. Why we need to integrate opensips with freeswitch?
Any info on this will be helpfull
Please, take a look at: http://www.opensips.org/Documentation/Tutorials-OpenSIPSFreeSwitchIntegration
It all depends on what you need.
