[Freeswitch-users] FS as a REDIRECT server

[Steven Ayre]

Note however that not all clients will follow 302 redirects. FreeSWITCH
won't be default for example.

The reason being it makes it easy to redirect a user along a premium rate
route when they think they're on a cheap/free one.

A SIP proxy or FS with bypass_media would work transparently, media would
still go directly between the targetted FS server and the client so you get
minimum lag. The SIP signalling is a much smaller amount of messages where
lag doesn't matter as much that its going via that proxy node. The load on
the proxy nodes is minimal since its only forwarding signalling not
handling any media.

Combine that with DNS SRV and you can have multiple sites providing the
proxy nodes to spread load, and add them as needed. Or use load balancers.
