[Freeswitch-users] Matching context based on sip_req_host

[Ken Rice]

If you are trying to match on the IP of the client, you probably really want
network_addr which reports from the ip stack which ip the invite came from,
using any other IP unless it is coming from a 100% trusted source leaves you
vulnerable to people spoofing the IPs inside the sip packets.

Also, the context on unauthenticated users goes with what is defined on the
sip profile, so you may need a sorting context
