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!
