asterisk users - Jan 2013 - Asterisk voicemail minimum length / silence settings

What I'm trying to achieve is that a voicemail message should be at
least 3 seconds long for it to be saved, but *after that* a prolonged
silence (e.g. 10 seconds) should terminate the call and recording.

My current settings (Asterisk 10.7.0 and 11.2.1) are:

   ; Minimum length of a voicemail message in seconds for the message to be kept
    ; The default is no minimum.
    minsecs=3

    ; How many seconds of silence before we end the recording
    maxsilence=10

With these settings, I'm getting the following warning message.

    WARNING[21671] app_voicemail.c: maxsilence should be less than
minsecs or you may get empty messages

What are the "right" settings for this situation?

Thanks all!

Depending on exactly what you want, those may be the right settings. What 
the warning is telling you is that with those settings, someone could 
reach voicemail, say nothing (silence on the line) and after 10 seconds it 
will hang up on them and deliver a 10 second silent message to their 
voicemail box. If you set maxsilence to something like 2 seconds, then it 
would hang up after 2 seconds and no message would be delivered. 

The only risk you run by ignoring the warning is that some users *WILL* 
get voicemails delivered that have no real audio, but simply be silent. If 
you can live with that, you settings will work fine.

We've used the following settings system-wide for about nine years without
one complaint or known issue:

[general]
format = wav49|pcm
maxsecs = 360
minsecs = 4
skipms = 3000
maxsilence = 3
maxlogins = 3
maxgreet = 120
maxmsg = 50
silencethreshold = 128
operator = yes
sendvoicemail = yes
usedirectory = yes
forcename = yes
forcegreeting = yes
saycid = no
review = yes
nextaftercmd = yes
tempgreetwarn = yes

Some of these things may be deprecated depending on the version you're
using.
