Typical Call Center

Anatomy of a typical call center

To better understand the terminology associated with the FlexCall system, lets take a look at a typical call center setup. Callers enter your system through one or more Toll-Free or Local telephone numbers. An Auto Attendant provides initial routing, to transfer callers to the appropriate Queue.

Callers wait in queue until an Agent becomes available to answer the call. Agents may specialize in one type of call, or may be cross-trained to take calls from multiple queues. A Supervisor is a special agent who has the ability silently monitor or actively join in to live calls in the system. Life cycle of an inbound ACD call

Life cycle of an inbound ACD call

The life cycle of an inbound call consists of the following segments:

All calls are initially answered by an auto attendant, which directs callers to different queues or departments. For example a caller pressing “1” might be routed to the Sales Queue.

The second step is queuing. This is an optional step, as calls are delivered immediately if agents are logged in and available. If all agents are busy, the call will wait in queue until it can be delivered. The caller will hear the pre-programmed delay announcements consisting of company promotions, general instructions, or music. If there are no agents logged in to take the call, the system will route the call to another extension or voice mail box, as configured in the queue settings.

The third step is to deliver the call to the next available agent and alert her by ringing her phone. During this time, the caller perceives that he is still in the queue and continues to hear the delay music. If the agent fails to answer the call, it is placed back on queue for delivery to the next available agent.

If the agent answers the call, he will be connected with the caller and free to talk, put the caller on hold, transfer the call to another extension, etc. This entire time is counted as the Talk Time of the call.

Finally, once the call ends, a rest period known as the Wrap-Up Time begins. During this time the agent may take care of chores relating to the just completed call, such as updating a CRM database. During wrap-up, the system will not deliver new calls to that agent.

Your business looks this empty when you don't answer a customer call

How many customer service reps do I need?

Proper staffing is an important factor in providing good customer service. Fortunately, the number of reps you’ll need for your queues can be calculated easily. Nearly a century ago, Danish mathematician Agner Krarup Erlang formalized the science of traffic engineering and queueing theory to come up with the optimal number of representatives needed for any given situation. Factors that go into the Erlang traffic model include average length of call, number of calls per hour, desired service level, and average wait time. Example suggested staffing levels based on the “Erlang C” formula follow:

Number of calls (hourly)102060
Avg. length call (mins)333
Wrap-up time after each call (mins) 111
Wait time (secs)202020
Service level80%80%80%
