400HD Series IP Phones for Teams
Version 2.3.410 52 Document #: LTRT-08641
The figure below shows the C435HD | C448HD | C450HD | C455HD phone user
interface.
After ‘User data reset’, network settings are preserved.
The option enables the data to be retained to handle devices more efficiently in
scenarios where the factory reset option is inappropriate.
All AudioCodes IP phones, including the C435HD,
can operate in a Survivable
Branch Appliance (SBA) environment. Branch office survivability is aimed at
providing limited calling functionality when the phone no longer has connectivity with
the Teams cloud. Basic functionalities are:
•
Making PSTN calls
• Receiving PSTN calls
• Hold & Resume of PSTN calls
If a user attempts to make a Teams call and the internet connection is down, they’ll be
notified that they can try calling a phone number instead.
A ‘No internet connection’ indication is displayed suggesting that calling a phone
number is available.
