Did you happen to

ec2-authorize default -P udp -p 16384-32768

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.

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>

<!-- TLS: disabled by default, set to "true" to enable -->
<param name="tls" value="false"/>

<!-- Port to listen on for TLS requests. (5061 will be used if unspecified)$

<!-- TLS version ("sslv23" (default), "tlsv1"). NOTE: Phones may not work w$

</settings>

Maybe someone can see what is going on here.

Thanks,
Damon

Try changing these lines and put your ip instead, that worked for me.

<X-PRE-PROCESS cmd="set" data="external_rtp_ip=stun:stun.freeswitch.org"/>
<X-PRE-PROCESS cmd="set" data="external_sip_ip=stun:stun.freeswitch.org"/>

Thanks Diego,

I have :
<X-PRE-PROCESS cmd="set" data="external_rtp_ip=75.101.142.208"/>
<!-- external_sip_ip
Used as the public IP address for SDP.
Can be an ip address or a string like "stun:stun.server.com"
If unspecified, the bind_server_ip value is used.
Used by: sofia.conf.xml dingaling.conf.xml
-->
<X-PRE-PROCESS cmd="set" data="external_sip_ip=75.101.142.208"/>

and im still having no luck .... my guess would be some issue with the elastic ip translation? then again im drawing at newbie straws .... im good with the others and nat/rtp have never been an issue ... is here.

Hi Brian,
Did you have any luck with the EC2 instances. I tried a few things, but I just cant get RTP to run through it. PLease let me know.

Hi,

When I first tried setting up freeswitch on ec2 I attempted to do
this through the quick and dirty wiki:
http://wiki.freeswitch.org/wiki/Quick_and_Dirty_Install
and the ec2 wiki
http://wiki.freeswitch.org/wiki/Amazon_ec2

This didn't work out for me. You also need to take a careful look at
http://wiki.freeswitch.org/wiki/Getting_Started_Guide#Firewall

then, for sip, setup a security group with the following ports enabled
(easiest to do with elasticfox
http://developer.amazonwebservices.com/connect/entry.jspa?externalID=609
):
udp 16384:32768
udp 4569
udp 5060
tcp 5060
udp 5080
tcp 5080
tcp 8000
udp 8000

make sure you make the security group, and apply it before you boot
the instance.
after this, the quick and dirty install guid worked just fine for
me. you'll just need to tweak the default dialplan
to your needs.

cheers

I have verified all of my steps based on the wiki. When I make an outbound call (or any call that would affect NAT), I hear the ring for a second than it disappears. The console shows:

I used the Quick and Dirty Install .... I believe I'm close and just missing something. Any other thoughts?

Thanks all for your help

You have to set the ext-sip-ip and ext-rtp-ip on the internal profile.
