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

---------------------------------------------------------------------- 
In trunk, reading chan_dahdi.c:parse_busy_pattern it appears that the
busypattern length can be 4.
But checking 1.6.1 length of only 2

busypattern=400,350,255,525

busypattern ignores the frequency, but detects the tone length, and quiet
length
