84 Matrix SETU ATA211 System Manual
in the Digest Authentication Table you configure in the New Delhi office, you must configure the User
Name and Password for the dedicated SIP trunks at the offices in Mumbai, Kolkatta, Chennai.
• With Digest Authentication configured at all branches, whenever an incoming call is received on the
SIP trunk, the SIP trunk will challenge the identity of the caller. When the digest credentials sent by the
calling device matches with the Digest Authentication Table, the call will be allowed on the SIP trunk.
• If the digest credentials do not match, the call will be rejected.
• Thus the Company can use Digest Authentication to restrict all call except those from its branch offices
on a SIP trunk.
