We have a UC320 which has been endless issues for us however we've finally got it going well excepting one issue, we're not able to hard set the codec to G711U rather than G711A. I've tried looking for a PMF file to do so as New Zealand region setting only has g711a and g729a.
The problem we face is we are unable to leave voice messages when in G729 or G711a hence the need to force G711u.
We're in the process of rolling out 100 of these systems to a multi-national company and require the forcing of g711U.
