GrandCentral works like a charm forwarding to my Gizmo number. I am also lucky enough to be one of the first to beta test a Canadian GrandCentral number, which means this service will be even more practical for me to use. I’ve been wanting a local number for awhile; Gizmo only offers Canadian area codes in Manitoba and Ontario. Skype offers none at all.
So when you call my GrandCentral number (778-785-6755), I’ve set up GC to forward to Gizmo. What I haven’t quite figured out yet is the voicemail. My Gizmo calls that are ignored/unanswered are bumping to GrandCentral voicemail, which is fine. However, I also have Gizmo voicemail activated, so I get an email and WAV file from Gizmo with nothing “in” it so to speak.
I think this a little bit of the untidiness you see when one app is not fully intergrated with another. See Alec’s post. For more reviews on GrandCentral and Gizmo, see Andy, Garrett Smith, Ken Camp, and Paul Kaputska.
