[Asterisk-Users] Voicemail doesn't hangup

[Christian Hecimovic]

If you search the archives, you'll see other postings on this problem. Here's 
what I did:

Add the following to voicemail.conf:

maxsilence=10
silencethreshold=256

The higher the silencethreshold, the less sensitive the silence detection 
stuff is. You may have to fiddle with this value a bit. When the voicemail 
app detects silence, it stops recording and rewinds itself to erase the 
silence. 

So now the voicemails record correctly, with no silence at the end. However, 
the line is still tied up because the Zap channel has not detected the hangup 
at the other end.

To force a hangup after leaving a voicemail, I added the following to 
app_voicemail.c in leave_voicemail(), right after the call to 
play_and_record():

if (res != '#' && chan != NULL && !strncmp(chan->name, "Zap", 3)) {
	/* Hang up the Zap channel only */
	free_user(vmu);
	ast_softhangup(chan, AST_SOFTHANGUP_EXPLICIT);
}

This is a despicable hack, but it does the job. Basically, if the user hasn't 
pressed #, the channel is up, and the channel is a Zap channel, then hang up 
after the voicemail has been recorded.

Hopefully this helps.
