VPN for Business Telephony
Short definition
VPN for Business Telephony: A protected network connection used to access phone systems remotely.
Meaning and how it works
A VPN can provide an encrypted network tunnel, but it does not eliminate latency, jitter or packet loss on a congested path. Protecting telephony and customer data combines technical controls, access rights and organisational processes. Different communication channels can require different safeguards.
Business applications
- Business scenario:
A branch connects its IP phones to a central PBX through a managed VPN tunnel.
What to check before implementation
Review lawful data handling, key and access management, retention periods, audit trails and recovery procedures. No single mechanism replaces an overall security policy.
