	If the phones were directly connected to Asterisk this would not be a
problem.  All the phones are proprietary Nortel digital phones that
connect directly to the Nortel box.  I need something like SMDI to
signal the PBX to turn the MWI light on.  Unfortunately all the
documentation I have read says that the Option 11 does not support SMDI
and I cannot find any other way of telling it to turn on the light when
there is voicemail waiting in Asterisk.
