Which rev of FreeSWITCH are you running? Also, collect a full debug trace of a working vs. non-working call so that you can compare what's happening. Put those on pastebin so others can have a look.<br>-MC<br><br><div class="gmail_quote">

To implement fallback to backup PSTN routes and do LCR my dialplan executes<br>
the following commands:<br>
<br>
set execute_on_answer=set hangup_after_bridge=true<br>
set some custom channel variables<br>
bridge sofia/gateway1/number<br>
set some custom channel variables<br>
bridge sofia/gateway2/number<br>
....<br>
<br>
This generally works fine if gateway1 returns SIP error, dialplan sets channel<br>
variables to another values and calls gateway2 immediately. But if GW1<br>
responds with 183 early media and SIP error after that, bad thing happens -<br>
dialplan continues immediately, sets channel variables, executes bridge<br>
application, but INVITE to GW2 is sent after 10 seconds delay. Caller gets 10<br>
extra seconds of post dial delay. I suspect the delay happens because of<br>
attempt to read audio frame, switch_ivr_originate() has the following lines:<br>
<br>
if (switch_channel_media_ready(caller_channel)) {<br>
tstatus = switch_core_session_read_frame()<br>
...<br>
<br>
Any advice how to avoid extra delay in this situation?<br>
