<p>OK. After a bit of further digging I've found that the CF_AUDIO flag is never set on one of the legs (I'm assuming it's leg A working on the principle that the thread always passes data from channel A to channel B). As the flag is not set the function calls <span style="font-size: 12pt;">switch_ivr_sleep()
for that leg </span><span style="font-size: 12pt;">and that causes the</span><span style="font-size: 12pt;"> code to </span><span style="font-size: 12pt;">write</span><span style="font-size: 12pt;"> a comfort noise frame.</span></p>
<p><br>
</p>
<p>I've tried changing the <span>flag value in the debugger and I do get the audio stream transmitted to the server (and echoed back) although it's a bit choppy. Now I need to try and determine where this would normally get set and why it isn't in this case.</span></p>

<p>OK, so I amended the FreeSWITCH.xml for FSClient to add a record_session action before the bridge action of the "number" extension in the default context of the dialplan section, and the client records the input audio stream fine.</p>
<p>I did the same thing in the "echo" extension of the default.xml in the FreeSWITCH dialplan folder and I get a recording of silence. This would seem to fit in with the fact that I don't see any RTP traffic data from the client to the server.</p>
<p><br>
</p>
<p>I have logs from both the server and the client (Debug Level set to 9 with SIP Trace active) but there is nothing notable logged between the start of the call and it's termination (I can provide the logs if that's of any help - and a WireShark trace).</p>

<div dir="ltr"><span style="font-size:12.8px">Under options in FSClient for the event socket you can change them but otherwise just connect like normal debugging and sip_trace might be a good start, you can use fs_logger as well to collect the logs for you
if desired. Let us know the result of the recording test as well.</span><br>

<div dir="ltr">Hi Paul,
<div>One place to start would be to record the call with FSClient and Freeswitch itself see if the audio is on the client but not FS. Enabling logging on the client/server using fs_cli and see anything interesting there. Finally make sure you have the right
mic input selected in the FSClient options.</div>
