3.3.3.2 Device
Here are the known device limitations in Version 1.19.584.
Table 3-12: Known Device Limitations in Version 1.19.584
Incident Description
-
[Device Manager] Network administrators are recommended not to provision phones
from both the Device Manager and the Microsoft admin portal, though they can
monitor from both Device Manager and Microsoft admin portal at the same time.
- It’s recommended to avoid connecting PoE and power simultaneously even though
no damage occurs. If a Power Supply is used, users should disable power from the
ETH port. In some cases, an endless auto-negotiation with the Ethernet switch may
occur if the phone is connected to the Power Supply and to PoE simultaneously.
IPPAN-2542
[C470HD, C455HD] Sometimes, touching one of the keys results in the speaker
emitting a little noise. This usually happens immediately after phone restart.
IPPAN-3283
When using multiple users on a single phone (i.e., if user A signs out and then signs
in with user B), AudioCodes’ Device Manager may present the wrong username.
IPPAN-2561
[C450HD] On some occasions, reconnecting a USB headset during a call causes
the call to be disconnected.
IPPAN-4910 [Device Duo] When a call comes in, there’s a mix of local & remote ringer.
- [Device Duo] During a Teams Desktop call, if the phone receives an incoming call
which is answered by hard key on the phone thus creating an active Native Teams
call, the first call (the Teams Desktop call) will be placed on hold (internal call) and
can be resumed only after the Native Teams call ends.
- [Device Duo] When music is played from the PC app via the paired phone, if you
perform a pause on the app, the window of the music player on the phone screen
closes and cannot be resumed from the phone (but can be from the PC app).
-
[Device Duo] When you’re in an active desktop call and you make an outgoing call
with a phone using its Expansion Module, there’s no option to return to the idle
screen during the active desktop call; the ‘back’ key doesn't return to the idle screen.
- [Device Duo] A delay of 10 secs occurs before the music player window appears.
-
[Device Duo] When any audio sound (not necessarily music) plays from the PC, the
music player window opens in the paired phone’s screen for a few seconds.
- [Device Duo] Starting a desktop call from the paired device isn’t supported.
IPPAN-6356
[Device Duo] On rare occasions, the voice quality in the direction of a remote party is
not smooth.
