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

[Chris Danielson]

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
