SSH

The phone can be accessed via Secure Shell (SSH) cryptographic network protocol after the network administrator signs in.

SSH is by default disabled and can be enabled with Administrator permissions in the phone screen (Device Administration > Debugging > SSH).

To sign in, the administrator needs to know their username and password; admin and 1234 are the defaults.

The default password must be changed before access to the device via SSH is allowed.
The default password can be changed per device in the phone screen, or via bulk configuration of multiple devices using Microsoft's TAC or AudioCodes' Device Manager.
After entering a password, the user is prompted to verify it. Criteria required for a strong password are provided: The password length must be greater than or equal to 8. The password must contain one or more uppercase characters. The password must contain one or more lowercase characters. The password must contain one or more numeric values. The password must contain one or more special characters.

SSH access allows administrators debugging capabilities such as:

Getting the Phone IP Address
Pulling files from the phone sdcard (using the curl command)
Activating DSP Recording
Deactivating DSP Recording
Installing the APK using SSH
