I have a UNIXPC with a rev. 2.2 Voice Power board in it and am
using Answering Machine software. Every now and then when the machine
takes a message the message length is truncated. I have the message
length set to 90 seconds but it will cut off and hang up the phone after
5 to 25 seconds. The problem seems to happen randomly. Most of the time
the messages are recorded with no problem but about 15% of the time
my messages are truncated. Has anyone else had or heard of a similar
problem ? If so what is the fix?

It seems that the library routines which handle the silence detection are slightly braindamaged and will sometimes detect people who speak in a monotone or softly, or an otherwise quiet phone call as silence. I believe there should be a slightly smaller threshold used in the silence detection value comparison in that library routine (haven't had time to investigate the proper fix). I don't know how you fix the problem in the AT&T Answering Machine software. I wrote my own answering machine program (to be posted to the net soon! as soon as I'm done moving) .. the way I solved the problem was to scrap the silence detection and just record 1 minute regardless. I don't like this idea, but I don't lose messages. BTW: An answering machine program is not hard to write if you start with the sample "hotline" program that AT&T gives you... The voice power board is really one of the better pieces of work for the UNIX-pc. ------- | Gil Kloepfer, Jr. | ICUS Software Systems/Bowne Management Systems (depending on where I am) | {decuac,boulder,talcott,sbcs}!icus!limbic!gil or gil@icus.islp.ny.us
