Getting Junk out of Modem Speaker/Local Handset

Does anyone have access playing messages to internal speaker or local
handset with ZyXEL Elite 2864I?
"vm play -v -s zyxel_2.9600.rmd" or "vm play -v -w -H zyxel_2.9600.rmd"
produces distorted messages only. The strange thing is, that there is no
junk on the line dialing into vgetty or using the shell script "message.sh
xxnumberxx zyxel_2.9600.rmd" that means using the telco line.
I compared the log-files of the tries above. They are identical, except the
choice of the voice i/o selection.
Before I upgraded my modem to ISDN this works fine. This time I try to find
out whether there is a bug in vgetty or in the modem (or in my
configuration...).
I also tried different versions of m/vgetty (now v1.1.21) and the modem
firmware (now 2.99i/2.01d). No success.
I switched from do_hard_flow true to false. Then some messages were played
correctly depending on the port_speed (voice.conf) and the voice compression
method selection, but the modem doesn't initialize afterwards properly (the
LCK..-file will not be removed).
And - very strange - messages over the telco line are now broken. This is
very stable if I use do_hard_flow true...
If someone doesn't have this problem with 2864I, please mail me the
configuration files.
Stefan.
