Incident

Description

IPPAN-3283 IPPAN-3343

[Device Manager] Administrators are recommended not to provision phones from both the Device Manager and the Microsoft Admin Portal. Monitoring from both Device Manager and the Microsoft Admin Portal at the same time is not an issue.
An endless auto-negotiation with the Ethernet switch may occur if the phone is connected to the Power Supply and to PoE simultaneously. It's recommended to avoid connecting them simultaneously even though no damage occurs. If a Power Supply is used, users should disable the power from the ETH port.
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.
The date format does not take effect on the phone when the configuration file is loaded from the Device Manager.
