- If you are in a menu that is more than one page deep and you press the exit button, it takes you back a page and you can never fully leave the app unless you pick up the handset and hang it back up. This is a bug with Yealink's "destroy on exit" feature, and a bug has been opened for a few months with them. This is fixed on some versions with newer firmware but not all versions.
- Waiting on Firmware 1.4.2 to allow having a application tell the phone to update its config.
- Requires rebooting the phone after completing login or logout, as the phone is not honoring pushing configs through XML. We have opened a bug report with Yealink on this.
