Policy, location, routing, and response quality connected in one operational model.
Security
Secure RTP
Media protection is valuable, but emergency paths often cross multiple administrative domains. Encryption support must be tested with media anchoring, recording, lawful retention, transfer and fallback requirements.
Media negotiation
->Keying/security
->Protected media
->Recording/fallback policy
What it does
SRTP can protect emergency media streams where end-to-end architecture and PSAP support allow it.
SRTP may secure voice, video or text media streams between compatible emergency endpoints and systems.
How it works
- Negotiates protected RTP media streams.
- Uses keying methods supported by endpoints and intermediaries.
- Interacts with recording and media anchoring systems.
Key interfaces and protocols
- SRTP
- SIP/SDP
- Media gateways
- Recording platforms
Systems it interacts with
- Video
- RTT
- Multimedia negotiation
- BCF
- Recording
Common failure modes
- Encryption blocks recording or transfer.
- Key negotiation fails.
- Fallback to unprotected media is not logged.
- Media relay does not support required mode.
Implementation considerations
- Test each media type and transfer path.
- Define acceptable fallback policy.
- Align privacy, recording and availability requirements.
Standards
- IETF media security practices
- ETSI NG112 references
