I opened a ticket with Switchvox support on this to hopefully get some indication of when/if any work would be done to support newer browsers. Unfortunately, the response was basically, 'We don't support those, but IE with compatibility mode might work.' It doesn't though.
That's very frustrating.
Fortunately I have found that Chrome 12 seems to work for everything I have tried so far. I just hope it keeps working.
I really don't want to have to turn my office into one of those companies that has to block updates and freeze on some archaic software release to support a particular business aspect, like companies that are still stuck on IE6 for some stupid vendor software thing.
It's sad really because you can tell so much work went into the admin interface for version 5 and the Switchboard as well but not getting it to work with IE 9 or Firefox 5 is really sort of embarrassing since both were in preview/beta for a good while before Switchvox 5 was released, if I remember right.
Well here's hoping it gets fixed 'real soon now'.
