[Freeswitch-users] SIP Proxy - Kamailio/Opens* load-balancing - simple example please?

[Ben Hood]

Hi Avi,

Albeit slightly old (nevertheless still relevant), here is a kamailio guide for freeswitch that might give you some inspiration: http://kb.asipto.com/freeswitch:kamailio-3.3.x-freeswitch-1.2.x-sbc.

HTH,

Ben

Also, most of them tell you about compiling code. FS has been released in packages - has opensips? That might cut off many steps from an updated tutorial.
