Re: [Freeswitch-users] session.recordFile issue when used right after "phrase" application

11 Apr 2008

      After debugging and fiddling with this further I discovered something of 
a useful workaround.  Here it is.  (works every time)

 while (session.ready() && dtmf.indexOf("#") < 0) {
    sayphrase("sayit", "Say something after the tone and press pound.");
    var tts = new TeleTone(session);

tts.generate("v=-7;%(100,0,941.0,1477.0);v=-7;>=2;+=.1;%(1400,0,350,440)");
    session.recordFile(FILELOC+filename,on_record_file,"",30,500,10);
}

The catch is to trick the user into letting the speech engine catch up 
by signaling when it is ready.  BTW, are there any plans of integrating 
something of a memcache (I know supjigator was researching it)? 

As-is every time a phrase is executed a call is made to the speech 
engine  switch_ivr_phrase_macro(...) and that call invokes a huge amount 
of iteration across the xml elements.  For testing, I did minimize the 
amount of iterations and found no significant difference in the time 
that the phrases stopped and the recording began.  I suppose the better 
way of doing things is to avoid using phrase macros and stick 
predominantly to pre-recorded sound files.
Cheers,
Chris

The following code seems to always perform the session.recordFile(...) 
function late.  And this leads to cutting off the first second of the 
recording.  The problem goes away when you remove the 
session.execute("phrase","...") call.  I even ran FreeSWITCH with the 
"-hp" mode to see if that changed things.  No luck.  Any ideas on what I 
can do other than setup a pre-recorded message to play?
