X-Lite automatically SUBSCRIBEs for MWI indication. Polycom and snom
do not do this by default, instead they assume that the REGISTER will
automatically cause MWI notifications.

chan_sip changed behaviour (by accident I suspect) somewhere between
version 1.2 and 1.6, and the patch basically puts back what went
missing. It is crude, but has not caused me any problems so far.
