[Freeswitch-users] issue with media on two internal gateways

[Michael Scheidell]

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