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

Sat Jan 29 03:54:19 MSK 2011

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".
