• Can be changed per device in the phone screen (the user first enters the default
password and is then prompted to modify it to a more complete password) or via
bulk configuration of multiple devices using Microsoft's TAC or AudioCodes'
Device Manager.
Criteria required for a strong password are provided. The password must:
• be greater than or equal to 8 characters in length
• contain one or more uppercase characters
• contain one or more lowercase characters
• contain one or more numeric values
• contain one or more special characters
 The voice quality of calls made via Device Duo has been improved.
 Automatic Gain Control (AGC) has been enhanced to improve voice quality.
 [Feature in preview] The devices now support certificate enrollment using Simple
Certificate Enrollment Protocol (SCEP) using Microsoft’s Network Device
Enrollment Service (NDES) server, thereby allowing device certificates and CA
certificate provisioning to be scaled to multiple devices.
After devices are provisioned with a SCEP-related configuration, they receive a CA
certificate from the NDES, issue a Certificate Signing Request (CSR) to the NDES
and receive a device certificate signed by the CA certificate (the one that the device
received from NDES).
Network administrators must configure the following three parameters:
• security/SCEPEnroll/ca_fingerprint
• security/SCEPEnroll/password_challenge
• security/SCEPServerURL
See the table in the device UM-AM for parameter descriptions.
 Device certificates can be provisioned in .pfx format (combining .crt and key). The
following parameter values can consequently be configured in the devices’
Configuration File:
• /security/device_certificate_url = <url>/certificate.pfx
• /security/device_private_key_url = NULL
• security/device_certificate/password=<pfx password>
The feature is also supported by AudioCodes’ Android Phone Utility (see here
for
more information).
 [Feature in preview] [Requires an updated 1.19 build] [Applies to C455HD and
C470HD] USB host mode is now supported as a feature in preview, i.e., the phone
can be connected to a PC via USB allowing it to be used as the PC’s audio device
such as an external speaker.
5. In the phone’s Device Settings > USB, the user must first enable ‘Audio Device
Mode’.
