Customer service, live people, almost always there (without waiting on hold) and super patient and helpful to get to a solution. I thoroughly appreciated the ability to call CS and tell them what I'd like to do (or see happen) and they're creatively helping me put it into action with the versatile applications within Jive.
Wifi stability (with MacBook Air). It's been a rough go. Jive has a pretty fat list of routers that its known to not work well with. And of course, my home and work router are BOTH on that list. I could buy their recommended routers, but geez, another expense.
Yet, after months of trouble shooting, I recently think it's maybe the MacBook Air I use. No one ever seems to review about the instability of their network connections, and that would be odd considering how much problem it is for me, but sure is for me (on WiFi). However I finally got an ethernet and plugged Mac directly to the router and the constant changing from Good Network to Poor Network disappeared. We've got another MacBook Air (similar year model) but haven't got the ethernet on it yet (used remotely).
So I still don't know if that's the true solution and sure as heck wish I could use WIFi on Jive more effectively, but until I decide on another computer (or troubleshoot with a different model like MacBook Pro, etc) I'm using ethernet.
IPhone w/ Jive app also behaves poorly but again, I think there something in there (WiFi Calling) that might be screwing things up.
One thing I will say is the Jive CS was outstanding on how they stuck with it and tested, including proving me with an explanation to use as a script for the Time Warner/Spectrum technician that was dispatched to look the signal (which Jive found to have packet loss and jitter in XS of what Jive can deal with).
If your using ethernet direct connection, it's a solid choice. WiFi, be ready to realize you might need to buy their recommended browser(s).
Remote accessibility, getting add'l telephone numbers (very inexpensive) and multiple lines (each one is a full expense). The text messaging is great, but could use some enhancements (like a signature and ability to put MMS content in there).
