Error Message

1000:1

On clicking the phone services banner, error code 1000:1 is displayed.

Generally indicates that the Device Configuration was downloaded successfully, but a setting may be missing or incorrect.

The most common example that has been observed is that Session Border Controller (SBC) TAGS are set incorrectly or are missing altogether. In this case, the client defaults to trying to register to the BroadCloud instead of to the BroadWorks server.

BroadWorks Device Failure

This usually indicates that there is a problem downloading a Device Config for the user. Confirm that the correct Identity/Profile Type is applied to users under User > Call Control > Shared Call Appearance:

  • For Desktop apps, it should be Business Communicator — PC

  • For Mobile apps, it should be Connect — Mobile

Sign-In Failure

1000:1507

BroadWorks Config Download Failure

On the BroadCloud or BroadWorks server, check under Group > Resources > Identity/Device Profiles > Profile > File and confirm that there is a valid config-wbx.xml config file applied to the client.

Note that all support for UCaaS config_wxt.xaml files is now removed.
