Digest Authentication:

Digest Authentication:

Sip provides a challenge based authentication called digest authentication. It uses username/password combination MD5 algorithm.

Client sends request for connection with UAS (registrar or redirect server), server send 401 unauthorized response to challenge the identity of client.

If client tries to initialize a request to proxy server, proxy server respond with 407 proxy authentication required to challenge UAC.

“WWW- Authenticate header” is sent in 401 responses by server. UA should include authorization header including credentials in next request.

“Proxy – authentication header” in sent in response sent by proxy server. UA should include Proxy- authorization header including credentials in next request.

Eternity VoIP server card supports digest authentication on SIP Trunk. Credentials can be configured in digest authentication table and feature can be enabled on Sip trunk parameters.
