Wholesale VoIP Termination: An Overview 

Wholesale VoIP Termination

Voice over Internet Protocol (VoIP) has revolutionized the telecommunications industry by offering cost-effective and scalable solutions to businesses of all sizes. VoIP termination, in particular, plays a critical role in this ecosystem, enabling the routing of calls from one provider to another until they reach their final destination. Wholesale VoIP termination, as the name suggests, deals with bulk trading of these services, fostering a thriving global market that continues to expand with the advancements in digital technology.

What is VoIP Termination?

The term refers to the process of routing a call from the originating party (caller) to the receiving party (callee) through various interconnected networks. It “terminates” the call, hence the name.  Particularly, these networks can be local or international, and the termination service quality largely depends on the quality of these networks and the route they take to reach the destination.


The Role of Wholesale VoIP Termination

In the context of VoIP, wholesale carriers are intermediaries who purchase voice traffic in bulk from telecommunication providers and sell it to other service providers, including retailers and VoIP service providers. In essence, it is all about  the bulk buying and selling of termination services, providing routes for millions of voice traffic minutes globally.

Wholesale VoIP termination providers typically have interconnections with multiple local and international carriers, allowing them to route long distance calls to virtually any destination worldwide.  Therefore, they play a vital role in maintaining a smooth and effective voice communication network globally by serving as the bridge between various telecommunication providers.

Benefits of Wholesale VoIP Termination


The main benefit of wholesale VoIP termination is cost-effectiveness. By purchasing termination services in bulk, wholesale carriers can negotiate lower rates per minute, which they can pass on to their clients.

Global Coverage

With interconnections to multiple carriers worldwide, wholesale VoIP termination providers can ensure global coverage.  Hence, they can route calls to almost any destination in the world, allowing businesses to communicate seamlessly with their global clientele.

High Quality

By having multiple routes to different destinations, wholesale carriers can maintain a high quality of their voip termination services.  Thus, they can choose the best routes for calls based on factors like cost, quality, and reliability.


As the business expands, the need for more calls also rises, so scalability should not be ignored. With a wholesale VoIP termination provider, a company can scale its operations without worrying about the technical aspects of handling increased voice traffic.

Major Wholesale VoIP Components

  • Softswitch

    This is a central element in a VoIP network, acting as a switchboard for VoIP calls. It controls voice traffic routing, signaling, and often also provides functions such as billing, call routing, and support for different communication protocols (like SIP). Softswitches are responsible for making decisions about call routing, negotiating between protocols, and managing connections between network points.

  • Billing Platform

    An essential component for wholesale VoIP providers, the billing platform manages rate sheets from various carriers, calculates call costs, issues invoices, handles payment processes, and often provides detailed reports. It should be capable of handling complex billing cycles, different currencies, and various payment methods.

  • Session Border Controller (SBC)

    SBCs secure VoIP traffic over the network and ensure the quality of service. They are placed at the edge of networks and perform functions like protecting against DoS attacks, toll fraud, and topology hiding, while also taking care of protocol normalization, transcoding, and traffic shaping.

  • VoIP Gateways

    These are physical devices or software that convert telephony traffic into IP for transmission over a data network. They’re used in wholesale VoIP to facilitate the connection of traditional PSTN networks to VoIP networks, essentially enabling calls between conventional phones and VoIP users.

  • IP Network

    The underlying transmission network, it needs to be robust and provide high availability, reliability, and quality of service (QoS) to ensure voice clarity, low latency, and no disruptions during calls.

  • Carrier Management

    This involves agreements with various local, regional, and international carriers to ensure that calls are terminated worldwide. Managing these relationships involves negotiating cost-effective rates and ensuring high service quality.

  • Routing Engine

    An advanced routing engine is crucial for optimizing international calling and the call routing process. It selects the most cost-effective and efficient routes in real time based on various parameters like cost, quality, and carrier reliability.

  • Security Measures

    These include firewalls, encryption protocols, and fraud detection systems that secure call data and protect the network from malicious attacks.

  • Customer Management System

    This system helps manage information about customers, their service usage, preferences, and other necessary details to improve customer experience.

  • Reporting and Analytics Tools

    These tools are necessary for monitoring call detail records (CDRs), traffic, quality of service, and other vital metrics. They provide insights for better decision-making regarding network operations, customer service, and profitability.

  • Regulatory Compliance

    Systems need to be in place to ensure that all services are compliant with relevant regulations. This can include local telecommunications laws, international standards, data protection laws, and more.

  • Technical Support and Service Desk

    A dedicated team that provides support for the wholesale termination infrastructure and addresses technical issues, ensures the smooth operation of services, and assists with customer inquiries or problems.


When selecting a wholesale VoIP termination provider, it’s crucial to consider several factors:

Reliability in VoIP Wholesale business
High Quality Telecommunication Services
Competitive VoIP Pricing


The provider should have a proven track record of offering reliable services. Downtime can significantly impact a business’s operations and reputation.


The quality of routes provided by the wholesale carrier plays a crucial role in call clarity. Higher quality routes will result in clearer calls, leading to better communication.


Wholesale VoIP termination providers often offer competitive prices due to their bulk purchases. However, pricing should not compromise the quality of service.
