Tablets, iPhones, and Androids wont connect to a Cisco Phone Server (10/5)

We used to have an 8.6 Cisco server (physical) and recently upgraded to 10.5 (virtualized). The new server is clustered with a publisher and subscriber.  They have self signed certs at this point and do not have DNS implemented. Configuration is through manual setup.

The old servers worked with Jabber on a variety of devices. While new devices WILL connect to the CUPS server and do IM / Presence, I cannot for love or money get it to connect and provide phone services or voicemail.  

When I attempt to use the reconnect option it tells me

Failed to get device configuration

I tried a mix of the Expressway install and config guide, combined with looking at the old phone server (which I still have, albeit isolated from production) to recreate the device profiles. Id love a simple how to guide on how to make Jabber work on mobile clients WITHOUT Expressway (though I will EVENTUALLY implement that too)

So, is there any reason that I couldnt make mobile devices on the local network (via wifi) connect to the phone server with their Jabber client?

If it should work, does anyone have a good step by step reference, preferably for 10.5

Lastly, anyone got any obvious "have you checked X" ideas?

#1 - No. Mobile devices on the wifi will have no problem connecting to a properly configured Cisco phone server implementation.

#2 - I never found one. Its all a hodge podge of the old 8.6 docs and the new expressway docs. The good news is, once youre familiar with the overall config the 8.6 docs will pretty much work

#3 - My ultimate problem was that I failed to add a line association to the device after I created it.
