Also called Transaction and Customer Contact. A term referring to telephone calls, video calls, Web calls and other types of contacts.
Combining traditionally separate inbound and outbound agent groups into one group of agents responsible for handling both inbound and outbound contacts. A system that is capable of call blending automatically puts agents who are making outbound calls into the inbound mode and vice versa, as necessitated by the incoming call load.
Call By Call Routing
The process of routing each call to the optimum destination according to real-time conditions. See Percent Allocation and Network Inter-flow.
An umbrella term that generally refers to reservations centres, help desks, information lines or customer service centres, regardless of how they are organized or what types of transactions they handle. The term is being challenged by many, because calls are just one type of transaction and the word centre doesn't accurately depict the many multi-site environments.

Database Call Handling
A CTI application, whereby the ACD works in sync with the database computer to process calls, based on information in the database. For example, a caller inputs digits into a voice processing system, the database retrieves information on that customer and then issues instructions to the ACD on how to handle the call (e.g., where to route the call, what priority the call should be given in queue, the announcements to play, etc.).
Day of Week Routing
A network service that routes calls to alternate locations, based on the day of week. There are also options for day of year and time of day routing.
Recorded announcements that encourage callers to wait for an agent to become available, remind them to have their account number ready, and provide information on access alternatives. In some systems, delay announcements are provided through recorded announcement routes (RANs).
Also called Queue Time. The time a caller spends in queue, waiting for an agent to become available. Average Delay is the same thing as Average Speed of Answer. Also see Average Delay of Delayed Calls.
A call which cannot be answered immediately and is placed in queue.
The number that the caller dialed to initiate the call.
Dialed Number Identification Service

The use of a binary code '1's and '0's to represent information.
Direct Call Processing
See Talk Time.
A signaling system that sends pairs of audio frequencies to represent digits on a telephone keypad.
An ACD feature that automatically reconfigures the number of rings before the system answers calls, based on real-time queue information. Since costs don't begin until the ACD answers calls, this feature can save callers or the call centre money when long distance charges apply.
Electronic Mail (E-mail)
Electronic text mail.
A strategy whereby enough agents are scheduled for the day or week to handle both the inbound call load and other types of work. Priorities are based on the inbound call load. When call load is heavy, all agents handle calls, but when it is light, some agents are reassigned to work that is not as time-sensitive.
A formula developed by A.K. Erlang, widely used to determine the number of lines required to handle a known calling load during a one hour period. The formula assumes that if callers get busy signals, they go away forever, never to retry ('lost calls cleared'). Since some callers retry, Erlang B can underestimate lines required. However, Erlang B is generally accurate in situations with few busy signals.
Calculates predicted waiting times (delay) based on three things: the number of servers (reps); the number of people waiting to be served (callers); and the average amount of time it takes to serve each person. It can also predict the resources required to keep waiting times within targeted limits. Erlang C assumes no lost calls or busy signals, so it has a tendency to overestimate staff required.
A Danish engineer who worked for the Copenhagen Telephone Company in the early 1900s and developed Erlang B, Erlang C and other telephone traffic engineering formulas.
