[Freeswitch-dev] FW: call is dropped after answer

[Francisco Scaramanga]

After answering the call  I set the channel status to CS_EXCHANGE_MEDIA, then the call is not dropped.

There are all kinds of things you can do, depends on what you want to do.  If you want to keep it alive you need to not return from that function.  You should be doing something to service the audio on the channel or put it in park.

okay, I added an application <action application="playback"  .../> to the dialplan and the call is not dropped anymore. 
 
But what if I just want the call kept alive by my application mod_skel?
 
Do I have to change the channel status for that?

It is hanging up because it has nothing left to do in the dialplan.  Add more applications after it or do more in your function.

  SWITCH_ADD_APP(app_interface, "my_mod_skel", "Modul skel", "test", mod_skel_function, "no Syntax", SAF_NONE);
 
The dialplan is 
 
 <extension name="sip_test">
  <condition field="destination_number" expression="^54322$">
      <action application="my_mod_skel" data=""/>
    </condition>
 </extension>

In the function mod_skel_function I do the following to answer the call.
 
SWITCH_STANDARD_APP(mod_skel_function)
{
 switch_channel_t *channel = switch_core_session_get_channel(session);
 switch_channel_clear_flag(channel, CF_PROXY_MEDIA);
 switch_channel_clear_flag(channel, CF_PROXY_MODE);
 switch_channel_answer(channel);
}
 
The problem is that sofia hungs up immediatley (see logfile below).
 
How can I keep the call alive? 
How can I pick up a new incoming call and start a conference?
