Incoming Network Signaling Validation
Yealink 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 asso-
ciated registered account.
l
Source IP address validation and digest authentication: apply both of the above methods.
