I am trying to setup a couple of gateways on my external profile that do not user usernames or passwords . How can I setup these gateways to match based on originating IP address? At the moment I have them defined in separate xml files in the sip_profiles/external directory. I am using the default external.xml I would like to be able to dial via this gateway and receive calls from these gateways. For example NYGW1.xml ------- > <include> <gateway name="NYGW1" cidr="10.10.10.1/32" description="Cisco Gateway Connected to Level3 PRI"> <param name="register" value="false"/> <param name="username" value="none"/> <param name="password" value="none"/> <param name="realm" value="10.10.10.1"/> <param name="proxy" value="10.10.10.1"/> <param name="from-domain" value="oneofmydomains.com"/> <param name="extension" value="inbound_oneofmydomains"/> <param name="caller-id-in-from" value="true"/> <param name="ping" value="25"/> </gateway> </include> When I remove the username/password params or set them to "" FreeSWITCH refuses to load the gateway. I tried adding the cidr="" to the gateway but no luck. Really all I want is for calls flowing in from 10.10.10.1 --- > FreeSWITCH External SIP Profile ---- > Match to NYGW1 --- > Dump into a context or extension from where I can route them as I please. Kind of how an Asterisk sip "peer" is matched on IP and routed to a context. Any ideas greatly appreciated!
