ANI and DNIS are two important concepts in the world of telephony,
particularly in the context of call routing and identification. ANI stands
for Automatic Number Identification, while DNIS stands for Dialed Number
Identification Service. Both ANI and DNIS are used to route calls to the
appropriate destination based on certain criteria.
ANI is a system that allows telephone companies to identify the telephone
number of the person making the call. This information is sent to the
recipient’s phone, where it is displayed as the incoming caller ID. ANI
works by sending a signal to the receiving telephone exchange when a call is
made. This signal contains the caller’s telephone number, which is then
displayed to the recipient.
DNIS, on the other hand, is a system that allows the recipient of a call to
identify the number that was dialed by the caller. This is particularly
useful for businesses that have multiple phone numbers and need to route
calls to the appropriate department or person based on the number that was
dialed. DNIS works by using a special code that is added to the incoming
call signal. This code contains the number that was dialed by the caller,
and it is used by the recipient’s phone system to route the call.
ANI and DNIS are often used together in call centers and other business
environments where it is important to route calls efficiently. For example,
when a call comes in to a call center, the ANI system will identify the
caller’s telephone number, while the DNIS system will identify the number
that was dialed. This information can be used to route the call to the
appropriate agent or department based on the caller’s needs.

In addition to call routing, ANI and DNIS are also useful for call tracking
and analysis. By collecting data on the telephone numbers of callers and the
numbers they are dialing, businesses can gain insights into call volumes,
customer behavior, and other important metrics. This information can be used
to improve customer service, optimize staffing levels, and make other
strategic decisions.
In summary, ANI and DNIS are two important systems that are used in
telephony to route calls efficiently and track important call data. By
understanding how these systems work, businesses can improve their customer
service and gain valuable insights into their call traffic.
