I don't want FS1 who talks to FS2 to try to use the PUBLIC rtp port. but I can't seem to see how.

FS1: 192.168.0.3 (public ip 204.89.241.135) listeing for trunk calls on 5060
FS2: 192.168.0.2 (public ip 204.89.241.150) listening for trunk calls on 5080

FS1 -> FS2 in Inivite: (then it tries to bind media to public ip, i get one way audio, and no DTMF)

     Contact: <sip:gw+secnap.com@204.89.241.135:5060;transport=udp>
            Contact Binding: <sip:gw+secnap.com@204.89.241.135:5060;transport=udp>
                URI: <sip:gw+secnap.com@204.89.241.135:5060;transport=udp>
                    SIP contact address: sip:gw+secnap.com@204.89.241.135:5060

(204.89.241.135 is the public ip, but these two boxes are internal)

FS2 listens on port 5080, FS1 listens on port 5060.

FS2-> FS1 (what is fair is FAIR..)

if tried so far:


put outbound-proxy in secnap.com.xml

   <param name="rtp-ip" value="192.168.0.3"/>
    <param name="sip-ip" value="192.168.0.3"/>
 in sofia.conf.xml
(noop)

in acl.conf.xml:

  <node type="allow" cidr="192.168.0.2/32"/>

no..

internal xml:

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

in external.xml also

making lots of calls from my cell phone.. watching traffic.
