OpenVPN
OpenVPN allows the configuration of a virtual private network (VPN).
Requirements:
•
ConfiguredVPN network interface type (Settings > Provider & PBXs >
Settings Configuration Manager Providers and PBXs)
•
OpenVPN configuration file saved into the telephone
•
OpenVPN certificate saved into the telephone
The telephone uses OpenVPN libraries to establish a VPN over a TLS/
SSL-encrypted connection.
Important:
When you restart the telephone, the time will be reset unless
it is updated automatically by a time server (NTP server). As data
packets are given a time stamp when they are encrypted, it is important
that the current time is configured on the telephone (see chapter
Settings > Date and Time
). A connection cannot be established via a
VPN if a data packet time stamp is different from the time on the
telephone.
