[asterisk-users] SoftHangup for emergency calls

[Mitch Claborn]

Setting up a group of analog lines to use for outbound emergency calls 
(911).  My current dial plan and debug output shown below.  It appears 
that when the SoftHangup() is executed that the line does not really 
hang up.  In the case shown, I had reduced the group to a single DAHDI 
(analog) channel and dialed in to that number from the outside. You can 
see in the output that the SoftHangup() was executed, but the call was 
not terminated - the outside caller stayed connected to something.  
Caller no longer heard the sounds from the menu he was in, but the call 
itself seemed to stay connected.

Asterisk 1.8 on Ubuntu

Any ideas?
