Hello y have 3 interfaces on my box 1 Lan to Internet 2 Lan to 192.168.1.x 3 Lan to 192.168.108.x I only have one domain in my openser I want to know a method to use the mediaproxy only when sending packet tru interfaces for example When making a call from lan 108 to internet or 192.168.1.x Im putting this kind of rules I set different number for number for each lan 1 for eth0 2 for eth1 3 for eth2 so each client has different number regarding the interface he sees .. Is this valid ?? if (from_uri=~"sip:|1[1]|2[0-9]|3[0-9][:@]" && to_uri=~"sip:|1[2]|2[0-9]|3[0-9]|4[0-9][:@]") { log("de 1 a 2\n"); use_media_proxy(); }; if (from_uri=~"sip:|1[2]|2[0-9]|3[0-9]|[0-9][:@]" && to_uri=~"sip:|1[1]|2[0-9]|3[0-9][:@]") { log("de 2 a 1\n"); use_media_proxy(); }; And not to use mediaproxy when calling within the same lan.
