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

[Kristian Kielhofner]

Unless you're looking at extremely high scale (several hundred to
thousands CPS) or tens - hundreds of thousands of call (yes, really)
why not just use another FreeSWITCH instance in bypass_media? On
decent hardware FreeSWITCH can easily manage a simple call routing
config in bypass_media into hundreds of CPS and several thousands
calls.

This can provide everything you've mentioned (and more) with many
additional advantages including not needing to learn SIP in and out to
make a SER-ish configuration useful.
