Some stats:

1) 1,351 calls over the previous 7 days (696 out, 654 in).
2) ~4100 minutes
3) the number that didn’t port right is ported (again, worked as of the day it said in the email, despite appearing to be there a week early. Outbound worked fine from the day it appeared in Unifi Talk.
4) call, handset quality have yielded zero complaints
5) transferred calls to groups show up as a whole group, so that’s neat (all nurses know that Nurse Z picks up phone on Day Y, but after 3-4 rings, they all are able to grab it)
6) you can’t see someone else’s line ringing and answer for them. There are workarounds (ring flows), but you’ll have to put some effort into this as there is no “here’s 20 extensions to view at once”
7) I think using the touchscreen to select contacts to transfer calls without knowing the extension is both useful but quite a bit slower than having a traditional phone with handwritten names/extensions on it, because you basically scroll through a cell phone address book. For 20 extensions, this isn’t cumbersome, but I do think that the interface could be better for somewhere that has a high call volume. It’s great for us though. Along those lines, I still haven’t touched a Max phone. But from every review, everything is just bigger. I would like to see more of a “secretary” format with “favorite” extensions in a more “traditional” look, because otherwise, there’s little benefit to the bigger phone (supposedly a better speaker. Even Protect isn’t utilizing the full screen with the Max phone though, so I’m really just not understanding the current state of affairs other than “bigger is better.”

So, the skeptic has come around. I have no reason to leave. There are some things I would change or like to see changed, but our needs our met and should only be improving (with an app in the next 2 weeks to meet their goal, though I’ll just place my wager on missing the deadline for softphone app).
