Summary:                    Etisalat UAE Disconnect Tone
Description: 
Hello.

We observed that Asterisk does not detect the Disconnect-Tone, and hence
it does not release a PSTN channel after an external calling party,
hangs-up. 

The PSTN operator is Etisalat and this occurs in certain parts of the
Dubai, UAE. 

The Disconnect-Tone pattern (frequency/duration in milliseconds) is show
below:

   400/400,0/350,400/225,0/525

4-length busy patterns specified in chan_dahdi are a feature of trunk. 
They can be set using a syntax pretty much identical to what alecdavis
specified above.  They are alternating tone and silence lengths.
