[Freeswitch-users] Routing inbound calls from gateways?

[Yu Boot]

Hello. Asked it sometimes ago, but unfortunately I didn't get any answer.

Is it possible to route inbound calls from the gateways described in SIP 
profile in other way but
             <condition field="network_addr" expression="^1\.2\.3\.4$" 
break="never">
?

context variable in gateway parameters seems to be totally ignored by 
FS, but it works for password-protected users.

Or why it's impossible to just auth that calls in FS by peer name-peer 
IP pair, like Asterisk does?
