add line like # Run vgetty
SX:2345:respawn:/sbin/vgetty ttySX where S1=com2 etc

then use /sbin/init q command to start vgetty 

- see http://merced.needsabeating.com/voicemail.html
for example vgetty setup

- minicom -s for general modem check
- setserial -ab /dev/modem  
  setserial -g /dev/ttyS*  for locating i/o & irq of internal modem

INSTALL & CONFIG VOCP
http://www.vocpsystem.com

notes:

set /etc/mgetty+sendfax/voice.conf
so that:
voice_devices is correct ttySX [1=com2, 2=com3]  
call_program is /usr/local/vocp/bin/vocp.pl





***vocp fix***

system hangs up after 44 seconds 
due to bug. fix detailed at
http://sourceforge.net/mailarchive/forum.php?thread_id=1923786&forum_id=3584
says to add:
 
 
 	'maxMessageTime'	=> 180,
 
 to the %Defaults hash in /usr/lib/perl5/site_perl/5.8.0/VOCP/Vars.pm (or
 wherever it is installed).

seems to work.
