I've always re-sold Ring Central to my clients if they were looking for a VOIP solution -- other than what their internet provider supplies -- and have been very happy with the service, though it does come at quite a cost per user.
In our own office we're using Ooma office as we've had it for years and it's been working "just fine", but without all the bells-and-whistles that Ring Central offers.
The feature that I really like with Ooma is that the Android app offers ring back in that, when we dial out, we don't have to use data as it dials us back via cell and then completes the call.
I have no experience with PBX but would like the make the plunge in office with the eventual goal of offering it as a solution to clients.
I've read all about DID, trunks, etc but am still quite lost. It's strange that I can pickup almost any technology very quickly and hit the ground running but that the whole PBX thing just goes right over my head.
Can anyone offer assistance in providing information as to what I'd require in order to get this going and whether I'd be able to utilize the same ring back functionality as Ooma offers? (I'd be porting our numbers out of Ooma (which I hear may be a bear)).
Cheers!
