Dave,
The list of officially supported Android phones can be found at the link below, but note that other phones may work with Jabber Voice, even if it is not officially supported at this time.

If you are unable to find an answer on the support forums, you should consider submitting a PER (product enhancement request) to your account team so they can create and submit the PER on Cisco's tracking system.
