Hi Marc,

I have now tested this with firmwares 2.99, 2.12, 2.11 and 2.10...
I have tested these on two ZyXEL 2864Is...

With the same result:

	With the default behaviour everything works perfectly!!!

	With the perl add-ons it almost works...

I attached the original mail and logfiles again:


My vgetty works perfectly when I just use it the standard way as a voice =
recorder
(greeting, beep, record, end). The voice plays nicely, faxes are =
received, AutoPPP
logins work...

I then installed the Perl scripts from CPAN =
(http://www.cpan.org/authors/id/Y/YE/YENYA/)
and altered two lines in the voice.conf:

	voice_shell /usr/bin/perl

	call_program /usr/local/bin/answering_machine.pl

With these I do not get any voice greeting, just silence, I get no beep, =
but I do get
a recording...

Can anyone help...?
