Description:Hi, I'm using TTS sofware to generate audio files and play them in real-time via asterisk. To do this I'm creating pipes to which asterisk is listening and to which TTS is generating audio.

When I use AGI command STREAM FILE, everything is ok, generated audio is played to the caller.
However, if I use GET DATA command, I can not hear the audio file. I'm using GET DATA to gather entered DTMFs. This solution worked in older version of asterisk (1.4.21 I guess).

Beneath I paste logs from console (verbose and debug on 100) from both cases.

A full debug log (you only have verbose) and a sample .agi script would help us triage the issue.

We require a complete debug log to help triage the issue.

This document will provide instructions on how to collect debugging logs from an Asterisk machine for the purpose of helping bug marshals troubleshoot an issue:

Hi,
I've uploaded the logs:
getdata-not working
streamfile- working

The agi is using asterisk-java and is using functions:
getData(java.lang.String file,long timeout,int maxDigits)
streamFile(java.lang.String file,java.lang.String escapeDigits)

Hmmm, says file is detected to have zero size. Have you verified that the file does indeed contain data? What happens if you use a file that has already been generated prior to the use of the script (i.e. a file from /var/lib/asterisk/sounds/en/)?
By: Maciej Krajewski (jamicque) 2010-09-21 17:30:20

it plays it nice (already generated file).
The point is that this file is generated realtime by TTS (that's why I use pipes).
And the strange thing is that using streamFile it works fine - beside the console warning the file is played by asterisk. However using getData disconnects the call without playing the file.
By: Maciej Krajewski (jamicque) 2010-09-22 13:53:52

And yes, the pipe contain data, but the thing with pipes is that the are filled with data only if something on the other end reads the pipe.
Stramfile seems to cope with it very well, getData not :( (I remind that in Asterisk 1.4.21 it worked fine).

should I deliver any more info?
By: Maciej Krajewski (jamicque) 2010-09-25 20:07:39

I've downgraded my asterisk to 1.4.19.2 and on this version getdata works fine with pipes.

I did have a very similary issue when I upgraded from 1.4 to 1.6. It took me a few days to find out the problem, just thought I would scrap it here if it helps you.
I was testing the new server(asterisk 1.6) at home behind NAT, where as the old one with 1.4 was a hosted server. I got it resolved by setting 'externip', 'localnet' and 'nat = yes'.

Thank for reply. However it's not the case. I use nat=yes to all my peers and friends all the time and I define externip and localnet.
The problem I've described is not caused by network problems. As I heve already written if I use stramfile AGI command everything is ok. Using getdata there is no sound.
The described problem is only related to pipes. Normal audio files are played correctly.

It works thanks.
