Configuring TLS Transport

The SIP protocol provides no means of encryption. However, the TLS transport option lets you wrap the unencrypted SIP channel within TLS encryption to secure SIP signaling between VSTG and the PBX.

This section provides general instructions on how to configure TLS for an IP PBX. For information about specific PBXs that have been certified, contact Vocera Technical Support.

Note: TLS transport encrypts only the SIP signaling between the VSTG and the PBX. It does not encrypt the voice communication between SIP clients.
