Re: [Freeswitch-users] jitter buffer effecting input callback in lua

4 Jan 2010


      There is no reason I can think of that would cause this.  Have you  
tried different phones to eliminate if it is an issue just with one  
type of phone?  Please open a bug on jira.freeswitch.org with a  
minimal script example to reproduce and details of the devices it has  
been reproduced with.

I have a very simple lua script (shown below my message)
This script plays a greeting, lets the caller record a message,  
detecting when caller is done by sensing a keypress.  It then plays  
the message back to the caller.
This works perfectly, except the audio quality of the recorded  
message is less than I had hoped.  To try to fix this, I have added  
a line to activate the jitter buffer.  This single line keeps the  
script from detecting the dtmf tones that end the recording, so the  
script just stays locked in record mode forever, until you hang up.
The log shows no problems.
How can I activate the jitter buffer, and still detect dtmf events?
Thanks for your help.

key ends the recording
    session:streamFile("/tmp/blah.wav");
