Matrix SETU VFXTH System Manual
Digest Authentication
Digest Authentication is a challenge-based authentication service of SIP to authenticate the identity of the
originator of SIP request in the INVITE message. The recipient of the request can ascertain whether or not the
originator of the request is authorized to make the request. When the digest credentials of the originator—User
Name and Password—in the INVITE message are authenticated and accepted by the recipient, the originator and
the recipient are connected.
SETU VFXTH supports Digest Authentication. The Digest Authentication feature works on the basis of the Digest
Authentication Table, in which the credentials, namely the User Name and Passwords of trusted/authorised calling
party SIP devices are stored. You must enable the Digest Authentication on the SIP Trunk and configure the Digest
Authentication table.
SETU VFXTH will check the Digest Authentication table,
•
when you enable this feature on a SIP Trunk.
•
when SIP Trunk mode is Peer to Peer and
Allowed IP Address for Incoming SIP Message
is set to
Any
.
When you enable this feature on a SIP Trunk, for all incoming calls (SIP requests),
•
SETU VFXTH will challenge the identity of the calling party, i.e. the SIP device initiating the request to send
its digest credentials.
•
When the calling party sends its credentials, SETU VFXTH authenticates the credentials by matching it
with its Digest Authentication Table.
•
If a match is found, the calling party will be authenticated and the call will be allowed on the SIP Trunk.
•
If no match is found, SETU VFXTH will consider it as invalid authentication information and reject the call.
You may use Digest Authentication to:
•
restrict access to SETU VFXTH to specific callers.
•
prevent unwanted or malicious calls.
