[Asterisk-Users] Unable to detect process 2 frames

[Peter Zeltins]

What does this error message mean?

WARNING[262160]: File dsp.c, Line 1106 (ast_dsp_process): Unable to detect
process 2 frames

I've been getting these a lot lately, sound quality seems to have suffered.
I'm using I4L driver with Fritz PCI ISDN card. However, even the regular
echo test sounds a bit choppy over LAN connection. Happens both on CVS and
0.4.0 versions

TIA,
Peter
