Telephony Connection Options

What's the challenge?

While new communication channels continue to crop up, the importance of voice remains. But physical hardware and network maintenance can be cumbersome and doesn't scale well. Meanwhile, your business is growing and today's needs may not be the same as next year's needs.

What's the solution?

A wide variety of voice services connectivity options can provide ultimate flexibility and choice—so whether you want to use the same vendor for your contact center solution and voice services, or you prefer to bring your own carrier and manage your own costs, you're able to keep up with your business' shifting needs, all while extending cloud benefits across the business to provide speed, stability and agility.

Use Case Overview

Story and Business Context

While new communication channels continue to crop up, the importance of voice remains. The speed and agility of the Genesys™ Genesys Cloud™ contact center platform connects your customer engagement and enterprise-wide unified communications with the telephony option that best fits your business needs. The widest variety of voice services connectivity options in the industry gives customers unparalleled flexibility and choice. Customers can choose Genesys Cloud Voice (Genesys telecom) for VoIP, use the cloud-based Bring Your Own Carrier (BYOC) option, or BYOC on-premises using a Genesys Cloud Edge appliance for local survivability. Customers can keep a carrier contract or existing PBX infrastructure, or consolidate using Genesys as a single vendor for all needs. Customers who choose Genesys Cloud are often attracted to the cloud technologies and microservices architecture that provide speed, stability, and agility for their business. Adopting a cloud solution for voice services is a future-proof approach—extending these same cloud benefits across a customer’s entire communications system.

Genesys Cloud Voice

Genesys Cloud Voice is an internet-based telephony service provided by Genesys that, when activated, provides public telephony access to Genesys Cloud services. (for example, Genesys Cloud Communicate and Genesys Cloud contact center.) The Genesys Cloud Voice service is built on Genesys Telecom, a Genesys second-generation multi-carrier platform, and registered Interconnected-VoIP provider, subject to all local telecom regulation. With Genesys Cloud Voice, customers can simplify their software and vendor management, consolidating down to one vendor and one bill. Deployment is fast with this all-cloud solution that easily scales. After enabling Genesys Cloud Voice for an organization, the administrator can purchase new phone numbers (for example, 800 numbers and DIDs) from a Genesys Cloud-provided inventory. Alternatively, they can also port existing phone numbers to the service for use with Genesys Cloud. From there, administrators can assign phone numbers to users, IVR systems, managed phones, or campaigns. Pricing is based per phone number and usage-per-minute.

Bring Your Own Carrier (BYOC).

Genesys Cloud BYOC refers to the ability for customers to define SIP trunks between Genesys Cloud and third-party devices or services. Customers can establish and maintain strategic carrier relationships and manage their own business voice costs. This service also eases deployment of global offices by enabling compliance with country-by-country telephony regulations. This service also allows customers to apply the speed, scalability, and agility of the cloud. A premises-based appliance is also available for customers who want local survivability. BYOC is available in two distinct offerings, named according to where the connection terminates against Genesys Cloud: BYOC Cloud: Customers can define SIP trunks between the Genesys Cloud cloud-based Edge & Media Tier and third-party systems over the public Internet. BYOC Premises: Customers can define SIP trunks between premises-based Edge hardware devices and third-party systems. Whether customers use BYOC in the cloud or a local Edge appliance, the solution enables them to create efficient and cost-effective telephony plans by applying local carriers and defining outbound routes for various number classifications.

Use Case Definition

Business Flow

How does Genesys Cloud Voice work?

After an organization enables Genesys Cloud Voice, the Genesys Cloud Voice administrator purchases new phone numbers or ports current phone numbers to the service. They can then assign phone numbers to users, IVRs, managed phones, or campaigns.

When you use Genesys Cloud Voice with a phone, it securely connects over the public Internet to the nearest available Genesys Cloud Voice region. After the phone connects to the Genesys Cloud Voice region, the phone authenticates and registers with the customer’s Genesys Cloud services. TLS encryption secures the communications between the phone and Genesys Cloud Voice service.

Business Flow Description

  1. Our customer's customer calls an 800 number for sales or support assistance.
  • Our customer purchases a toll-free (1-800-xxx-xxxx) number from a carrier of choice.
  • Anyone can call this 800 number from a mobile device or landline and reach our customer via the PSTN.
  1. PSTN routes the call to the appropriate cloud carrier that is registered to the 800 number.
  2. The cloud carrier connects to Genesys Cloud Media Tier & Trunking Services over the Internet.
  3. The call connects to a Genesys Cloud ACD or business user via the Internet.

Business and Distribution Logic

Business Logic

All voice calls to external participants route through a Genesys Voice Solution: Genesys Cloud Voice or Bring Your Own Carrier.

  • Does the customer have an existing carrier relationship?
  • Does the customer want to keep this existing carrier relationship or port services to Genesys Cloud Voice?

The first example uses a toll-free 800 number. The number in this example can also be interchanged with the DID number. For example, any number reachable from the PSTN.

Example 1

  • Customer has an existing relationship with Carrier ABC that owns their 800 numbers.
  • Customer selects BYOC open and integrates our solution with Carrier ABC for PSTN services.

Example 2

  • Customer does not have an existing relationship with any carriers and needs to buy net-new 800 numbers.
  • Customer selects Genesys Cloud Voice and purchases new 800 numbers from within our platform.

Example 3

  • Customer has an existing carrier relationship with Carrier ABC that owns their 800 numbers. Customer wants to consolidate and sees efficiencies in porting these numbers to Genesys Cloud Voice.
  • Customer selects Genesys Cloud Voice and completes the necessary paperwork to transfer or port services from their previous carrier to Genesys Cloud Voice. For 800 numbers, this process is referred to 'resporg'. It updates the PSTN so that it knows what carrier to route the traffic to. In this example, PSTN has to be notified that the 800 number is now registered to Genesys Cloud Voice.

Distribution Logic

All voice calls to external participants route through a Genesys Voice Solution: Genesys Cloud Voice or Bring Your Own Carrier.

The Number Plan / Number Assignment configuration defines all distribution logic of calls to business users or agents. Customers can assign a phone number to a user or to an IVR with ACD Routing. For more information about distribution logic after routing the number per number assignment, please refer to Genesys Business Communications or Genesys Call Routing use cases.

Real-time Reporting

Genesys Cloud provides real-time reporting for managers, supervisors, and agents. Real-time reporting includes contact center performance and metrics in dynamic views and dashboards. For more information about real-time reporting for your business requirements, see About reports, views, and dashboards.


Real-time reporting dynamic views display historical and real-time contact center metrics for interactions, agents, and queues. Use these views to meet your business needs.

To view in-progress and completed interactions, see Interactions view. The interaction's details page shows the interaction overview that is a visual representation of the interaction. The interaction overview provides information about the interaction participants and the type of interaction, including a waveform for voice interactions.

Agents Performance views include agent metrics, time in statuses, and evaluations. To understand agent activity, view detailed performance metrics for an agent or group of agents, in the Agents Performance Detail view.

Queues views provide insight into both real-time and historical queue performance data, including queue activity and metrics. See real-time information about a specific queue in the Queues Activity Detail view, including the queue's current interactions, agents, and service levels in one view. The Queues Activity Summary view updates in real time, and shows real-time statistics for all queues at the same time.


Performance Dashboards allow you to monitor the real-time activity for the contact center. These include service level, ASA, and the number of customers interacting and waiting. Display selected metrics and performance data about your contact center by creating Dashboards. With the Metric and Chart widgets, you can select the metrics about the queues, users, wrap-up codes, flows, or flow outcomes you want to see on your dashboards.

Historical Reporting

Reports show you historical data about your contact center and assist you in understanding your business needs. Use reports to see past metrics and data about the contact center. Reports include a pre-defined set of metrics. You set parameters for reports such as which users or queues to include, which media types to include, what date range to report on, and when to run the report. You can schedule reports to run at certain times, and you can run the report directly from your reports list page.

Using historical reports with dashboards and views gives you an accurate picture of your contact center's performance.
