It's Interop time, so there's going to be lots of enterprise network gear getting introduced for the next week or so. Some of it will be VoIP related, and some will be pretty interesting.

PTT is very big in public safety markets, which this isn't really made for--but it's perfect for retail and warehouse applications.
