Incoming Network Signaling Validation
Yealink IP phones support the following three optional levels of security for validating incoming network signaling:
l Source IP address validation: ensure the request is received from an IP address of a server belonging to the set of
target SIP servers.
l Digest authentication: challenge requests with digest authentication using the local credentials for the associated
registered account.
l Source IP address validation and digest authentication: apply both of the above methods.
