[Freeswitch-users] Routing inbound calls from gateways?

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?
