In the terminal, I get repeatedly this message:
[Oct 22 16:07:06] ERROR: app_jack.c:559 queue_voice_frame: Output

..while the conversation is active.
The sample rate conversion seems fine. I inserted a log call after the
resample_factor was set:
*resample_factor = to_srate / from_srate;
[Oct 22 16:07:06] ERROR: app_jack.c:221 alloc_resampler: factor=12.000000
[Oct 22 16:07:06] ERROR: app_jack.c:221 alloc_resampler: factor=0.083333
I run JACK at 96kHz, which factor here confirms to have found. 8kHz*12=96kHz.
I'm running on GNU/Linux with asterisk-SVN from today. I'm running
I have quite an extensive setup of JACK apps, so I know that JACK itself
is not a problem.
Any pointers as to what I can try?.
