Encryption ensures no one else can read the data sent to and from the IP Office. Encryption is the application of a complex mathematical process at the originating end, and a reverse process at the receiving end. The process at each end uses the same ‘key’ to encrypt and decrypt the data:

The IP Office can encrypt any data sent using a number the following algorithms:

In general, the larger the key size, the more secure the encryption. However, smaller key sizes require less processing. The system supports encryption using the Transport Layer Security (TLS) protocol.
