Incident Description
IPPAN-4465 On some occasions, the sign-out action cannot be completed smoothly and requires
a hard reboot of the phone.
IPPAN-3941 On some occasions, the phone prompts the user to re-enter the user’s password
even though it was already entered remotely during the ‘Sign in from another device’.
Re-entering the password works around the issue.
IPPAN-3752
[C450HD, Call Queue] The second agent is not notified when a call is received by
the first agent (Android OS 7 bug).
IPPAN-2270,
IPPAN-4548
[RXV80, C450HD] The device sometimes displays ‘Poor internet connection’ in the
main screen for a few seconds and then disappears.
IPPAN-2566 A muted phone that receives another incoming call and rejects it results in a
non-voluntary unmute of the original call.
- When using right to left languages (Hebrew, for example) the soft dial pad and
presented dial string are reverted.
IPPAN-2476 [C470HD] The phone displays an irrelevant ‘Meeting’ string when a parked call is
picked up.
IPPAN-2510 An incorrect date format is displayed when the current language is Simple Chinese.
IPPAN-3946 The sign-out action occasionally doesn’t land in the Sign-in screen. Instead, the
phone shows the ‘Device settings’ screen, or gets stuck while displaying a ‘signing
out…’ message. A reboot can be performed to recover from this scenario.
- [Better Together] Peer-to-Peer (direct) calls are still not supported.
- [Better Together] Pairing the phone with the PC client might in some cases fail.
Quitting the PC client and restarting it may solve the issue.
