I have an intermittent problem with telemarketers calling and triggering the voicemail, but not actually leaving a message.
Each time it happens I have to spend ages going through the voicemail checking and deleting them all.
One of these idiots called sixty seven times a couple of nights ago…
Is there any way for the voicemail system to automatically ignore or delete zero length or very short messages (like a ‘minimum duration to save’ setting)?
Yes, you can specify the minimum number of seconds a voicemail must be.
In /etc/asterisk/vm_general.inc there are a number of voicemail options, including:
maxmessage=180 ; max length of vm message
minmessage=3 ; Minimum length of a voicemail message in seconds
maxsilence=5 ; Wait for 5 silent seconds and end the voicemail
Adjust as needed but be careful otherwise you may lose valid, but short, messages.
You might need to trigger a reload for this to take effect.
Hope that helps!
If they’re calling from the same number, blacklist them…
