Fully integrated

The Callisto module functions, Callisto phone book, and MS Exchange/ Outlook or MS Dynamics are already integrated with COC. Other systems can be integrated using the smart Event/Action function or a separate API.


Thanks to the intuitive and straightforward COC Operator console, agents quickly feel at home in their work. Agents can benefit from individual working methods among many available operating options and preferences.

Easy to manage

Using the COC configurator, administrators can quickly and efficiently configure all COC clients, assign roles, groups, or HTML windows, define event/action functions, and much more.

All features in detail

Features from A–Z Description
Accessibility The COC solution supports the operation by blind or visually impaired persons and is compatible with operating aids for the PC, Braille displays, and vocalizers (e.g., JAWS 2018 version or higher). COC is certified by the company Pappenmeier (pappenmeier-rehatechnik.de).
Advanced conferencing This function allows ad hoc conferences to be initiated and controlled. Participants are clearly displayed and can be added or removed very easily. The conference can be ended again at the push of a button.
Alarm button With the help of an HTML window, a corresponding alarm button can be easily integrated by using the Callisto Alarming Collection.
Auto-Attendant/IVR Combined with the ProfACD module, the agent has extensive configuration options for call acceptance, announcement management, and call distribution. A single-stage IVR is already included. Multi-stage IVR’s can be configured with the ProfIVR module.
Auto-Update CTModule provides free COC client updates from time to time. These can be imported automatically or through the administrator.
Busy queue COC allows to park calls which called to busy extensions in the busy queue until the recipient is available. As soon as the called extension is free, the caller is connected directly to the destination from the busy queue. A separate window in COC shows the overview of calls in the busy queue, from which the attendant can retrieve a caller at any time by double-clicking.
Calendar integration COC receives the calendar information of the monitored users and the agents through the Microsoft Exchange connection. This information is displayed in the user’s presence area.
Call list/reporting A separate window in COC displays the call list. Here, the agent can see, filter, or search for all calls he has processed or missed. Further detailed reports can be found in the ProfACD module in the reporting area.
Call pick-up from the queue Regardless of its position in the queue, any call on hold can be answered with the pick-up function.
Callback During a call, the attendant can send a callback request with option a) callback to himself or b) callback directly to the caller to a user or another attendant with an XML-enabled Cisco phone. In this case, the subscriber receives a message with all the call details and the “Dial” button on their phone. Once they click “Dial,” they will be connected to either the attendant or the original caller, depending on the selected option.
CRM/ERP integration COC is integrated with Microsoft Dynamics CRM. COC opens the corresponding lead or contact in an external Dynamics CRM page based on the incoming call number. Other CRM or ERP systems can be integrated with the smart event/action function or a separate API.

The COC Modul is installed as a client/server application in a few steps on the user PC. For the main configuration, a COC configurator software is available for the administrator. On the server-side, the COC client connects to the COC proxy service, which is part of the Callisto platform, but can also run as a standalone server. The two options for the COC installation:

  1. COC as a Modul component of the Callisto Platform
  2. COC as a standalone product (in this case, the combined functionalities are not available)
DTMF The user can send DTMF tones directly via an input keyboard during a call, e.g., to control IVRs.
Fallback option If the attendant initiates a blind transfer or a transfer in ringing state and the dialed user does not answer the call, the call is returned directly to the attendant or to any other number (e.g., on hold) after a defined time, depending on the option selected.
Forward to voice mail The operator can very easily forward any call to any voicemail box of Callisto VoiceMail.
Global number plan (E.164 support) E.164 numbers supported.
green-IT Lowest resource requirements in the industry with the highest performance: 2 to 8 CPUs, 2 to 6 GB RAM, 80 GB HD, up to max. 1’000 parallel calls per image.
High Availability Yes
HTML window COC can display web pages with addable HTML windows. Besides individual web pages, many useful Callisto pages can be added, such as ProfACD Viewer, ManagerAssistant Group, News, or others.
Incoming call notification For incoming calls, the COC displays a call pop-up with the caller’s name from the phonebook, a picture of the person if available, and options to accept, reject, or forward the call to voicemail.
Individual keyboard shortcut COC supports user-defined hotkeys for numerous functions. Basically, the operator can operate the entire call management in COC without a mouse.
Intelligent agent support Based on the call status, COC optionally offers the agent all possible next steps in a pop-up overview for direct clicking or further call processing. Alternatively, double-clicking on the next COC UCM action executes the most appropriate function.
Internal pick-up list The “Internal pick-up list” window displays all calls to internal users. With the appropriate authorization, the agent sees these calls and can pick them up if necessary.
Microsoft Outlook integration COC has a Microsoft Outlook integration. Once activated, COC displays all Outlook contacts in a separate window that can be searched, distributed or even dialed. The creation of an Outlook note or e-mail from COC is very easy.
Monitoring and coaching The supervisor can manage his group through the COC configurator. With the ProfACD Viewer, he is always informed about the processes in his group. COC also provides him with buttons for monitoring and coaching his team.
Park calls COC supports the “call parking” function. The operator can park any connected call with a single click or key combination. Any authorized operator can then answer parked calls by double-clicking in the COC parked calls window.
Pause management In connection with the Callisto module ProfACD, the agent can set his status to pause or not ready, which means that he will not receive any more calls during this time. This status will be taken into account in the reporting accordingly.
Phone note The agent can easily send a predefined call note to the target person from the call list via e-mail during a call or afterward.
Phonebook integration The Callisto PhoneBook module is integrated into a separate window in COC. In that one, the public or private phonebook contacts can be searched, transferred, or dialed.
Presence COC has its own presence solution and Cisco Unified Presence Server (CUPS) integration. In conjunction with CUPS, the statuses (presence and rich presence) can be changed directly in COC or the Jabber or Webex client. Microsoft® Outlook® calendar entries are displayed automatically.
Provisioning Manually or automatically from Cisco UCM through AXL or Microsoft AD, LDAP/OpenLDAP system, and CSV files. Web services (REST) supported.
Queue In connection with the Callisto module ProfACD, the queues are configured and displayed clearly in a COC HTML window.
Queue monitoring With Callisto module ProfACD (Viewer), the queues are clearly displayed in a COC HTML window. In addition to that, agents and status, defined key figures, all calls in detail, as well as a pick-up function per respective call are displayed.
Reliability Apart from the stability of the Callisto system, in the event of a COC failure, the operator can continue to handle the call typically with his telephone or client. If the queue management (ProfACD) fails additionally, a ring call is usually configured on the PBX if the Callisto service is unreachable.
Scalability Callisto supports per instance, depending on the scenario, up to 200 COC clients, up to 10’000 users, unlimited number of queues and up to 960 lines for the calls in the queues.
Security https, SIPS, password and PIN security, appliance security, integrated firewall
Supervisor The supervisor can manage his group through the COC configurator. With the help of the ProfACD Viewer, he is always informed about the processes in his group. COC also provides buttons for monitoring and coaching his team.
Supported phones/clients COC supports all Cisco phones, as well as Jabber and Webex clients.
Usability COC offers a user-friendly and efficient user interface. Thanks to the flexible window arrangements, the drag & drop functions, as well as the possibilities to integrate other Callisto modules, COC helps the attendant to process the call quickly, clearly and with maximum efficiency.
VIP distribution Between 0-5 VIP stars can be assigned to users and entries of external persons in the PhoneBook module. Based on this, the position in a queue for VIP’s can be defined.
Voice recording COC has dedicated buttons to control the Callisto VoiceRecording module.

Callisto Operator Solution – Your best choice


A comprehensive feature set, drag-and-drop support, flexible arrangeable and addable window concept, intelligent call assistance, and multiple integration options make COC the most efficient, flexible, and powerful attendant solution for UCC solutions.


Every agent has his needs for individual and efficient call transfer: the comprehensive configuration options, the different performance features, and the unique window concept fulfill a professional agent's wishes and support him individually in his work.


When there is a high volume of calls, it must be possible to work efficiently without being distracted from the essential - the customer. That is what COC’s concept is based on, making the most important functions available to professional agents in a clear, customizable manner with intelligent call support.

Best Service

Successful call handling

Callisto’s COC attendant solution supports users to focus on their customers. When transferring calls, the calling customer always has priority. Therefore, the operator must efficiently and conveniently handle each call quickly. Example of a possible scenario:

  1. Incoming calls showed by ringtone and pop-up with caller information, possibly with a picture. The agent can prepare for the customer if he knows who is calling.
  2. In his ACD window, he sees the call with the call details and duration, including the color scale. If a higher-priority VIP customer calls now, he will be assigned to the agent. Furthermore, in this call status, it is still possible to take the call of another customer from the queue.
  3. The agent now accepts the call, e.g., via pop-up. It is possible that the correct customer window in MS Dynamics CRM opened immediately based on the caller number.
  4. The caller wishes to speak with sales. The agent possibly sees the name of the responsible salesperson assigned to this customer in the MS Dynamics CRM window, knows the name by heart, looks for it in the COC user overview, or selects his own “Sales” tab. Based on the integrated information from the salesperson’s Outlook calendar, he can see that the salesperson is still busy for half an hour in a customer meeting.
  5. The agent puts the customer on hold and quickly queries the sales secretary’s office to ask for the deputy. A brief search of the name in the user overview shows that the presence status is green, and the secretary is not currently making calls.
  6. The agent takes the customer’s call back and informs them about the upcoming transfer; he clicks on the call and drags it to the target person by pressing the control key (blind transfer).
  7. If a post-processing time is set, it will run before the operator is free again for the next call.

It fits your needs

Who would not like to set up his desktop according to his needs? That is exactly what our COC window concept does. The agent can resize each window in COC and place it precisely where he wants it. Windows can be grouped so that each can be clicked with its tab. Additional windows, such as Callisto ProfACD, ManagerAssistant Group, and Messages, can be added if required. The flexibility to set up the work agent desktop makes the difference to any other agent solution in the market.


Teamwork of functionalities

Modularity and flexibility are in the DNA of the Callisto development team. That is why the COC agent solution also provides the most diverse and complementary options for the operator functions. Complement your COC basic functions with the following ones:

  • Callisto professional call center module ProfACD incl. viewer and supervisor: configuration of complex call center scenarios with comprehensive overview and supervisor functions
  • Integration with your CRM/ERP system, such as Microsoft Dynamics CRM: COC automatically opens the correct page in your customer system based on the incoming call number
  • Integration with Microsoft Exchange/Outlook: absences are displayed directly in the presence overview, Outlook contacts are displayed for search/dial/transfer, journal entries can be activated, or notes can be added
  • Callisto PhoneBook: Callisto PhoneBook contacts can be searched, dialed, and transferred in a separate tab, or additional phonebooks can be integrated with PhoneBook.
  • Integration with Cisco Unified Presence Server (CUPS): fully synchronized presence status of the monitored subscribers, including rich presence (RPT) and the current phone status for each user, is displayed clearly.
  • Callisto VoiceRecording: easily operated through COC function keys in the menu
  • Callisto alarm solutions: adding an alarm button or triggering an alarm conference in the agent overview can be easily realized with the Callisto HTML window concept
  • Activation of event/action functions: COC provides freely definable and expandable events (e.g., incoming calls) and the resulting actions (e.g., opening an application window).
  • and many more

Team support

For supervisors, it is essential to be able to provide the best support to their agent team. For this reason,COC assists the supervisor with crucial functions:

  • All details about queues, agent capacity load, and call volume are displayed in the ProfACD Viewer window
  • Additional agents can be easily added by logging in to overloaded queues from any location
  • The COC monitoring function allows individual team members or calls to be easily monitored with a prior announcement.
  • Through active monitoring or directly with the COC coaching function, team members can be supported in a challenging conversation by whispering supportive words (whisper coaching).

Blind Handicapped support

Accessibility for Visually Impaired People

The COC agent solution supports the operation of blind and visually impaired people. This is achieved through complete compatibility with operating aids for the PC, Braille displays, and Vocalizer (e.g., JAWS 2018 version or higher). Specialized integrators (such as F.H. Papenmeier GmbH & Co. KG) perform the expert installation at the customer’s site.
