What Is Wholesale VoIP?
Wholesale VoIP is the provision of VoIP services at a higher volume at a discounted rate, typically offered to IT service providers who then resell the services to end customers.
Wholesale VoIP services are sold in bulk to businesses that need extensive communication capabilities. This allows them to offer a range of services to their customers without having to purchase and maintain their own infrastructure.
Unlike standard retail VoIP services, wholesale VoIP is not sold directly to consumers themselves. Instead, it's sold to businesses that can resell the services to their own customers.
Wholesale VoIP providers offer discounted rates because they're providing services in bulk. This makes it a cost-effective option for businesses that need to provide communication services to their customers.
How It Works
Wholesale VoIP works by transforming voice signals into digital packets, which are transmitted over the internet to their receiver. This process allows for unhindered communication between clients and providers.
At its core, VoIP tech uses the public internet for point-to-point communication. Wholesale providers implement state-of-the-art solutions to ensure consistently reliable VoIP solutions.
Wholesale VoIP providers offer services at a larger volume and discounted price, providing cost-saving opportunities for their clients. IT service providers can rebrand and resell these services under their own name in a process called white labelling.
Wholesale VoIP involves routing voice traffic between telecommunications service providers using internet protocol instead of traditional PSTN infrastructure. The key services offered by wholesale VoIP providers include voice termination, voice origination, SIP trunking, and more.

Here are the main services offered by wholesale VoIP providers:
- Voice Termination: Completing calls from an IP network to a destination on another network.
- Voice Origination: Receiving calls from the PSTN or other networks and delivering them to a VoIP network.
- SIP Trunking: Connecting IP-based PBX systems to the public telephone network via the internet.
- Direct Inward Dialing (DIDs): Virtual phone numbers that allow callers to reach a specific extension on a VoIP system.
- Toll-Free Numbers: Numbers that can be routed to a VoIP system, allowing customers to call without incurring charges.
- Value-Added Services: Features like call routing customization, real-time reporting and analytics, and API access.
What Is IP?
IP is the backbone of VoIP technology. It's the internet protocol that transforms voice signals into digital packets, allowing them to be transmitted over the internet to their receiver.
These digital packets are then routed between telecommunications service providers, often across countries or regions, using internet protocol rather than traditional PSTN infrastructure. This process is known as wholesale VoIP.
Here are the key services offered by wholesale VoIP providers:
- Voice Termination: completing calls from an IP network to a destination on another network
- Voice Origination: receiving calls from the PSTN or other networks and delivering them to a VoIP network
- SIP Trunking: connecting IP-based PBX systems to the public telephone network via the internet
- Direct Inward Dialing (DIDs): virtual phone numbers that allow callers from the PSTN to directly reach a specific extension on a VoIP system
- Toll-Free Numbers: numbers that can be routed to a VoIP system, allowing customers to call a business without incurring charges
- Value-Added Services: features like call routing customization, real-time reporting and analytics, fraud protection, and API access
Wholesale VoIP providers offer these services at a larger volume and at a discounted price, which allows resellers and service providers to offer competitive pricing to their end-users while maintaining healthy profit margins.
Technical Architecture
A VoIP solution uses the public internet for point-to-point communication, allowing for consistently reliable connections.
Wholesale providers implement state-of-the-art solutions to ensure unhindered communication, which is a key benefit for their clients.
Using the public internet for communication means that wholesale providers can offer a large number of clients with reliable VoIP solutions.

This approach also enables wholesale providers to team up with resellers to connect with end-users, making it easier to reach managed service providers (MSPs) and value-added resellers (VARs).
Resellers benefit from increased revenue and improved branding by taking advantage of the expanding market, which is a result of the connection between wholesale providers and resellers.
The connection between wholesale providers, resellers, and clients is mutually beneficial, ultimately leading to a better experience for the end-users.
With so many providers offering different services, selecting the right one can be a challenging task, but knowing what to look for can make the process easier.
Choosing a Provider
Choosing a provider is a crucial step in getting the right wholesale VoIP services for your business. You should compare multiple providers systematically, considering at least three to five providers before making a decision.
To do this, create a structured evaluation process that examines each provider across consistent criteria, such as feature completeness, pricing structures, support quality, technology platform capabilities, integration and customization options, and scalability. A comparison matrix can help you organize this information.
Here are some key factors to consider when evaluating providers:
- Network Quality & Reliability: Look for Tier-1 interconnects, direct connections, and global Points of Presence (PoPs).
- Global Coverage: Ensure the provider offers VoIP termination to all your vital destinations.
- Call Quality Assurance: Verify low latency, minimal jitter, and a high Mean Opinion Score (MOS).
- Customer Support: Confirm that 24/7 expert support is available, preferably with dedicated account managers.
- Advanced Fraud Prevention: Seek AI-powered tools for proactive fraud detection and the active elimination of grey routes.
- Technical Integration: Check for BYOC support, UCaaS/CPaaS integration, robust APIs, and support for a range of Codecs (G.711, G.729, Opus, HD Voice).
- Billing Transparency: Look for detailed billing reports, clear per-second billing increments, and flexible payment options.
- Case Studies & Track Record: Request case studies that prove success with businesses similar to yours.
