asterisk users - Sep 2003 - Warnung: File dsp.c, Line 1198 ???

Hi,

I have a problem with asterisk-0.5.0 which I don't
understand. The monitor says when making a call:


*CLI>     -- Executing Dial("SIP/roger-c456", 
"Modem/ttyI0:BYEXTENSION|60|tTm") in new stack
    -- Called ttyI0:1234567890
WARNING[196621]: File dsp.c, Line 1198 (ast_dsp_process): Unable to 
detect process 2 frames
WARNING[196621]: File dsp.c, Line 1198 (ast_dsp_process): Unable to 
detect process 2 frames

and the last 2 lines are repeated approx a 100 times every second.
Regardless which one of my 2 snom phones is used.

I have a snom 100 and a snom 200 attached via SIP. With the
snom 200 I have nevertheless good sound quality, but with
the snom 100, I have a very bad sound. Sound seems to be
interrupted several 10 times every second for a very short
time.

I already tried different codecs - hard to say, if there were
any differences.


Any ideas, what went wrong?


Roger.
