Cloud calling without the headaches

Cisco Webex® Calling (formerly Cisco Spark Call) is your phone system in the cloud. All the business-class calling and collaboration essentials your organization needs, without the management complexities.

Product overview

Webex® Calling (formerly Cisco Spark Call) is a cloud-based phone system, part of the Cisco Webex suite of collaboration services. It is optimized for midsize businesses and provides the essential business calling capabilities you are likely to need. With Webex Calling, there’s no need to worry about the expense and complexity of managing phone system infrastructure on your premises anymore. We take care of the Webex® Cloud so you can focus on what matters most.

You can choose from a wide range of Cisco® IP phones to make and receive calls. Enjoy the calling features you are used to from a traditional phone system to help run your organization smoothly and never miss a call. If you are a mobile worker, or you are out of the office, make and receive calls on your smartphone, computer, or tablet, using the Cisco Webex Teams app.

Webex Calling (formerly Cisco Spark Call) seamlessly integrates with Webex Teams and Webex Meetings, so you can take collaboration inside and outside your organization to a new level. Your staff, customers, and business partners can make high-definition audio and video calls from the office, from home, or on the go. You can share screens, files, and messages, and can also whiteboard, to turn any call into a productive meeting. You can also add Cisco Webex Board, Room, or desk devices to help you get the most out of Webex Teams and Meetings and improve teamwork.

Webex Calling (formerly Spark Call) features and benefits

Simpler, intuitive communication and collaboration through your organization.



Phones for every user and office location

Webex Calling (formerly Spark Call) supports a wide range of Cisco IP Phone 7800 and 8800 Series for any job role and office location: in the main office, in a branch, in public areas, in a conference room, or in your home office. All connected together by the Webex Calling service.

Comprehensive Private Branch Exchange (PBX) capabilities for business calling

Welcome callers to your organization with a virtual receptionist, hunt and pickup groups, shared lines, and/or personalized voice mailboxes. Make calls with extension numbers, direct-inward-dial numbers, URIs (email-style addresses), or directory-based dialing. Enjoy mid-call features, including hold with music, resume, forward, and transfer.

Enhanced communication and collaboration for mobile devices

Webex Calling enables you to make and receive calls on your laptop and mobile devices wherever you are by using the Webex Teams app. With the Webex Teams app you can further enhance communication with a rich set of messaging, screen and file sharing, and meetings capabilities.

Security and encryption

Secure your communications and protect your business from threats. Webex Calling (formerly Spark Call) encrypts phone registration, activation, call signaling, and audio and video streams, as well as voicemail. Even the management is secure, because all administrative and end-user interfaces are encrypted.

Simple cloud management

Webex Calling (formerly Spark Call) is simple and intuitive to provision, manage, and use. We take care of the Webex Cloud so you can focus on running your business. The Webex Control Hub provides a simple interface for IT to make changes, and a self-care portal means users can handle basic settings and preferences for themselves.

Unlike other cloud phone systems from other vendors, with Cisco Webex you can do much more.

Redefine business calling in your organization with the complete Webex suite of applications, including Webex Calling, Meetings, and Teams.

Cloud phone systems

Webex Meetings helps you forget about technology, so you can focus on having productive meetings. Joining meetings is a breeze for everyone, no matter how they connect, even for guests. Audio and video are crystal clear and screen sharing super simple. Meet from anywhere using an app on your computer, smartphone, or tablet. Or join with a group of colleagues using a Webex Room Series device. Need a recording? That’s simple too, with just a single click to record.

Webex Teams enables continuous teamwork. Bring people together from across organizations in a space to share messages and files securely. Escalate to or schedule a follow-up meeting to dive deeper, share ideas, and co-create with interactive whiteboard and annotation, and make decisions as a team. After the meeting, keep the conversation going in the same team space, iterating until you’ve achieved your objective.

Webex Calling (formerly Spark Call) supports a wide range of Cisco IP phones

Webex Calling (formerly Spark Call)

Choose from a broad selection of phones for all types of users and situations. The phones are available in charcoal and white to suit any office environment. You must purchase phones separately from the Webex Calling monthly per-user service, and the phones require the Webex Calling phone OS. Finally, anyone can set up the phone. All you need to do is plug it in and enter a registration code, and the phone registers itself.

System requirements

Because Webex Calling (formerly Spark Call) is your phone system in the cloud, you need only a few basic things in place to enjoy a successful deployment and enable business-class calling and collaboration for your organization:

Internet access

Internet access with DNS is required for phones to be registered and be activated.

Firewall settings

Most organizations deploy an internet firewall, or internet proxy and firewall, to restrict and control the traffic that leaves and enters their network. To enable access to the Webex Calling service and Webex Teams services from your network see: Network Requirements for Webex Teams Services.

Bandwidth requirements

Each device in a video call requires up to 2 Mbps in each direction, and each device in an audio call requires 92 kbps in each direction. Phones at idle need minimal bandwidth.


Ethernet or Wireless 802.11a/b/g/n/ac network. 5 GHz is recommended for wireless to reduce interference.


Power supplies or PoE switch to power any IP phones you deploy. Consult the documentation for the IP phone models you choose for more details.

PSTN services

In order to make and/or receive calls from the PSTN, you need PSTN services from one of our preferred media partners. See the PSTN services section above.
