[Asterisk-Users] Hangups after voicemail

[Martin Pycko]

Do you have silence in the channel when the remote user hangs up or busy
tone ?

If you have silence you can use maxsilence=x_seconds in voicemail.conf
with
Voicemail2 application and that will make sure the calls are hanged up
after x_seconds of silence in the channel.

If you have busy tone then use the busydetect=yes in zapata.conf.
You can also limit the length of the voicemail message with
maxmessage=x_seconds in the voicemail.conf

Martin
