Callisto ProfACD – Your best choice


The ProfACD module can be easily configured or expanded from a small call distribution system to a full-blown call center. Everything is there, everything is possible.


The flexibility of ProfACD enables comprehensive configuration options, easy expandability with other modules, the option to add features, a wide range of applications, and more.


ProfACD fulfills the enterprise needs of having an excellent Call center solution with loads of functionalities at an unbeatable price.

Smart and personal customer reception

The customer telephone reception is the business card of a company. Dealing with customer interfaces shows that fast, personal and polite contact is essential and must be tailored to the company. This is why our ProfACD development team focuses on the flexibility and efficiency of the solution. The company should have a personal touch, the customer should be served fast, friendly and goal-oriented, and here is how ProfACD can support you:

  • Callers are given preferential treatment based on their call number, prioritization of the queue, or their VIP status
  • Individual announcements and processes can be easily configured and adapted
  • Callers can be informed of their waiting time and position in the queue
  • Queues can be set up based on departments
  • Define overflows and alarms due to increased call volume
  • Monitor calls and coach agents during calls
  • The current call center status can be consulted at any time in the Viewer, and the detailed reporting can be consulted for the learning curve.

Call distribution and announcements for every need

ProfACD already has a single-level IVR (Interactive Voice Response system) built-in by default. This is sufficient in many cases but can easily be supplemented with the comprehensive, multi-level IVR Module: ProfIVR. From very simple to complex customer routing systems can be created to connect every customer with the right contact person via telephone. Each company can configure its call distribution algorithm individually.

The personal announcements can be played in each IVR level or individual waiting queue. Every individual waiting queue also has a variety of options for informing, entertaining, and guiding callers. Following are some examples:

  • General greeting announcement
  • Configurable announcement sequences for waiting customers
  • Configurable playback time of the announcement
  • Any music on hold and announcements can be added and changed
  • Time controlled announcements for outside working hours or holidays
  • Definable time for overflow or announcement with caller-selectable forwarding to voicemail


Extensive queue management for happy customers

The ProfACD module provides various configuration options apart from the comprehensive announcement and music-on-hold management, the prioritization of queues and callers, or the option for different call distribution algorithms. Some of these are:

  • Post-processing time
  • Automatic loop configuration detection
  • Automated agent log out after a defined number of missed calls
  • Set corresponding timeouts and forwarding or alerting when all agents are logged out and when all agents are busy
  • General timeout for a queue with the option for an overflow or forwarding to voicemail, if confirmed by the caller
  • Various alarms and overflows like, e.g., max. number of waiting callers, max. calls over a defined time, min. number of available agents, and much more.

Customers – The agent’s focus

Agents should be able to concentrate on what is most important: the customer. That’s why ProfACD makes agents’ lives much easier. Let’s see how:

  • Agents can log in/out of all assigned queues or individual queues directly with any Cisco phone or through ProfACD viewer using COC, Jabber, Webex, Gadgets, or any other phone with IVR.
  • After a call, agents have time to review (according to configuration) the call and prepare for a new call
  • Each agent can click pause or not ready whenever needed
  • On the XML-enabled Cisco phone or via ProfACD viewer through COC, Jabber, Webex, or Gadgets, agents can always see the status, performance data, or traffic volume in their queues
  • The Callisto COC agent solution increases the agent efficiency significantly through intuitive operation and clear presentation
  • Thanks to the automation options of ProfACD and the integration possibilities of COC with CRM/ERP systems, the processes for agents can be significantly simplified.

Learn from history

Not only the live data in a call center is essential, the history is also elementary and interesting for planning and control. That is why the ProfACD module provides extensive reporting for detailed evaluations. The authorized people can take advantage of the following:

  • Detailed overview of a customer’s entire call, incl. call sequence, time/duration, abort and forward reasons, queue selected in IVR, agents involved, etc.
  • Evaluations from the agent’s point of view, incl. number of calls, different times, and timeouts
  • Queue evaluation, incl. number of calls, call abandonment, and different times
  • Agent login/out evaluation per agent and queue
  • Evaluations can always be filtered by queue, agent, or time period
  • Non-ACD calls can be filtered by: without inbound, with inbound, with outbound or both
  • Evaluations are available as data or as graphics or for export to MS Excel
  • Privileges can be set per user in such a way that the data can only be viewed for defined evaluations, according to the 4-eyes principle

Timing is crucial

Doing the right thing at the right time: with ProfACD Time Management, many processes can be automated very easily, so that calling customers always receive the right information promptly. Possible settings:

  • Non-availability times per weekday with time period and corresponding announcements, any forwarding or forwarding to VoiceMail
  • Holiday or vacation times with time period, one-time or yearly, and corresponding announcements, any forwarding or forwarding to VoiceMail
  • Various configurable timeouts with subsequent action to accelerate and optimize the call process
  • Post-processing time for agents and much more

Overview for the supervisor

Team leaders or supervisors in a call center must always have an overview of what is happening in their team and be able to (re-)act correctly in each situation. ProfACD provides various functionalities for this purpose:

  • Configurable ProfACD viewer with a complete overview of all activities and agents in the call center
  • Easy agent administration
  • Receipt and evaluation of alarm messages
  • Extensive reporting
  • Monitoring and coaching function for training and quality control (with COC module), and much more
