As we've successfully implemented four spectralink 8440 (wifi) with lync 2013 during our office move, we've "faced" the feature music on hold. As far as I've read the documentation, it's only possible to get music on hold working through our own streaming server/service, especially if we want to provide our own music on hold files.
Is someone out there who has implemented music on hold for the 8440s? Is there any (maybe open source) product you want to recommend?
As I've figured out lync 2013 is not able to provide such a service, asterisk may be, but the documentation I've found for asterisk is old/imprecisely or wrong.
Any ideas/experiences are appreciated! Thanks, Moritz
