I have tried a number of times to configure an account on communicator for andriod to connect to a local PBX on the internal wireless. It doesn’t seem to matter what I enter for the user or domain. The connection never completes. I have tried just the username which is the same as the extension number. I have also tried following the example i.e. firstname.lastname@example.org but nothing seems to work. Am I missing the formatting for a field? For the domain I’ve tried host name and IP address for the PBX.
