DNIS
DNIS (Dialed Number Identification Service) is a telephone service that identifies for
the receiver of a call the number that the caller dialed.
Users could configure DNIS to allow the IP phones to display which trunk is passing
the call.
Suppose a company has two trunks, one for sales service, one for support
service.
To make a difference between two kinds of calls, we can configure two DNIS
for the two trunks.
Log in MyPBX and go to
PBX→Advanced Settings→DNIS Settings
, click
to create a DNIS.

these trunks may have multiple numbers,and multiple DNIS can be set for one SIP
trunk.

1. PSTN trunk do not need to set DID number.
2. If you do not set the DID number, all calls through selected VoIP/BRI trunk will
show the DNIS name as Caller Name.
