Summary:                    [patch] wcbxxp fails reading signalling
Description: 
The problem is detected in the calls that the package CONNECT includes an
information element type number connected "(in calls to the bedside of a
call center can inform the caller of the number that really has heeded the
call).
The error is not due to the ease, but the size of the package.
By placing an analyzer monitoring basic access, we see that  the operator
sends the package (correct) and that the receiver asterisk (namely dahdi)
has invented a character.
We get at log something like this chan_dahdi.c:10710 dahdi_pri_error: XXX
Message longer than it should be?? XXX
-- Processing IE 41 (cs0, Date/Time)
-- Processing IE 76 (cs0, Connected Number)
chan_dahdi.c:10710 dahdi_pri_error: XXX Message longer than it should be??

I'm having problems (see https://issues.asterisk.org/view.php?id=16151) with
DIGITAL calls connected to a NT port
on B410P and with this patch my success rate changes from none, to once,
then a dahdi restart is required.

before patch I see both as below, call appears to setup, but no data
transfer.
