If you are really bored, keep reading. After some random sleuthing, I found this case study about Telerhythmics (The IDTF that GMV owns).
encstelerhythmicspdf.pdf (mitel.com)
As I said, very boring. It does, however, mention that Jan Callawy is/was the CEO of Telerhythmics. There was some comment recently about Stephanie Callaway leaving GMV. There is also one other Callaway (a male) mentioned elsewhere in relation to Telerhythmics. I'm not on LinkedIn, so can't investigate further. It seems like it was a family business before GMV purchased it. Make of that what you will, if anything.
