How it works
SRTP protects media packets, but it does not replace secure SIP signalling or proper key management. Protecting telephony and customer data combines technical controls, access rights and organisational processes. Different communication channels can require different safeguards.
Business example
Compatible endpoints use SRTP to help protect the confidentiality and integrity of call media.
What to consider
Review lawful data handling, key and access management, retention periods, audit trails and recovery procedures. No single mechanism replaces an overall security policy.
