I just want to add that I enabled STUN on my cell so now the SDP message in the INVITE to voip.ms contains the public IP of my phone, but it still doesn't work.

Subject: [Freeswitch-users] Outbound only calls don't connect when bypass_media is true.

Hello,

I'm a new user of freeswitch, so please bear with me. I have the
following setup:
voip.ms <- SIP over UDP -> my desktop running freeswitch <- SIP over TCP -> my nokia cellphone on AT&T wireless. This setup is intended to conserve the battery usage.
I've managed to make everything work well when I'm calling in over any phone to my cell phone, and freeswitch is enabled to work in bypass_media = true, even though by cell is behind NAT on at&t's network. Things break when I pick up my cell and try to call my home phone (or any phone for that matter). This is the relevant snippet from my dialplan:
<extension name="outbound">
  <condition field="destination_number" expression="^1?([2-9]\d{2}[2-9]\d{6})$">
    <!--<action application="set" data="bypass_media=true"/>-->
    <action application="bridge" data="sofia/gateway/voip.ms/1$1"/>
  </condition>
</extension>

Like shown above, my call will go to my home phone. When I uncomment the bypass_media tag, my call will not connect. Here are the siptraces
I replaced my real home phone number in the with "MYPHONE".
