Jabber is a brand, not a specific product. There are older clients that are still visible in the app stores (e.g. Jabber Voice, Jabber Video, etc) but these are only published for customers who have a legacy install already deployed. The "Cisco Jabber" app is what you would use for a new deployment.

Remember that the IM&P server software or functionality is free; all you need is the necessary compute power and time to install/configure it.
The only reason they are releasing Phone Mode in the first place is to eventually be able to end of life the IP Communicator client. That's likely a ways out still though considering how many features CIPC has that Jabber still lacks.
Here's the relevant config checklist for phone mode. Make sure you've taken care of each of these steps:

the same time it kind of is, but for the most part you don't configure
the softkeys. You enable or disable them via TCL. Here is the long
answer. Be sure to read the whole thing or e...
