[Freeswitch-users] SIP, NAT and Amazon EC2

[Damon Brown]

Ive Tried the following with no success:

internal.xml

    <param name="ext-rtp-ip" value="75.101.142.208"/>
    <param name="ext-sip-ip" value="75.101.142.208"/>

Ive also tried just changing the vars.xml file.  I also tried forwarding the incoming rtp connections to my test pc.  all with no audio success.  I am sure im doing something wrong I jsut cant find it.

I found another suggestion on the wiki of creating a "double nat" that listens on 5090.  That didnt change anything either, here is that information:

<settings>
    <param name="debug" value="0"/>
    <param name="sip-trace" value="no"/>
    <param name="rfc2833-pt" value="101"/>
    <param name="sip-port" value="5090"/>
    <param name="dialplan" value="XML"/>
    <param name="context" value="default"/>
    <param name="dtmf-duration" value="100"/>
    <param name="codec-prefs" value="$${outbound_codec_prefs}"/>
    <param name="hold-music" value="$${hold_music}"/>
    <param name="use-rtp-timer" value="true"/>
    <param name="rtp-timer-name" value="soft"/>
    <param name="manage-presence" value="false"/>
    <param name="aggressive-nat-detection" value="true"/>
    <param name="inbound-codec-negotiation" value="generous"/>
    <param name="nonce-ttl" value="60"/>
    <param name="auth-calls" value="false"/>
    <param name="rtp-timeout-sec" value="1800"/>
    <param name="rtp-ip" value="$${local_ip_v4}"/>
    <param name="sip-ip" value="$${local_ip_v4}"/>
    <param name="ext-rtp-ip" value="$${external_rtp_ip}"/>
    <param name="ext-sip-ip" value="$${external_sip_ip}"/>
    <param name="rtp-timeout-sec" value="300"/>
    <!--<param name="enable-3pcc" value="true"/>-->
    <!-- TLS: disabled by default, set to "true" to enable -->
    <param name="tls" value="false"/>
    <!-- additional bind parameters for TLS -->
    <param name="tls-bind-params" value="transport=tls"/>
    <!-- Port to listen on for TLS requests. (5061 will be used if unspecified)$
    <param name="tls-sip-port" value="5081"/>
    <!-- Location of the agent.pem and cafile.pem ssl certificates (needed for $
    <param name="tls-cert-dir" value="$${base_dir}/conf/ssl"/>
    <!-- TLS version ("sslv23" (default), "tlsv1"). NOTE: Phones may not work w$
    <param name="tls-version" value="tlsv1"/>

  </settings>

Maybe someone can see what is going on here.

Thanks, 
Damon

You'll have to set an ext-sip-ip and ext-rtp-ip on the internal.xml  
profile on ec2 duplicate them from the external profile.
