[Asterisk-Users] Hangups after voicemail

[Christian Hecimovic]

Hi Martin,

Yes, silence detection in voicemail is working. I am using Voicemail2 with the 
silencethreshold set to 256. However, the line doesn't hang up after the 
silence is detected; instead, Voicemail2 exits after recording the voicemail 
correctly, and Asterisk loops back into the main menu as if the # key was 
pressed because the channel is still alive. Then it times out after 15 
seconds, as you can see below.

From extensions.conf:

[incoming]
exten => s,1,Answer
exten => s,2,DigitTimeout,5
exten => s,3,ResponseTimeout,10
exten => s,4,BackGround(corp_greeting)
include => locals
include => errors

The locals context consists of macros which look like this:

exten => s,1,Playback(transfer,skip)
exten => s,2,Dial(${ARG2},20)      
exten => s,3,Voicemail2(u${ARG1})  
exten => s,4,Goto(incoming,s,1)   
exten => s,103,Voicemail2(b${ARG1}) 
exten => s,104,Goto(incoming,s,1)   

So after a voicemail is left, there is a Goto back into the incoming context. 
It all works great, except for when the line gets tied up by the DigitTimeout 
and ResponseTimeout bits when hangups aren't detected.

I've tried using BUSYDETECT_MARTIN with busydetect=yes and it didn't work. The 
channel stays up after the outside caller hangs up. 

Since all of our inside phones are SIP lines, there is no problem detecting 
hangups when a voice conversation is taking place, since Asterisk obviously 
detects SIP hangups correctly whether it's SIP to SIP or SIP to outside line. 
The problem is really only when outside callers leave voicemail.

Thanks,

Chris
