What is Voice Termination?

Voice termination is the process of routing and delivering telephone calls from the originating network to the destination endpoint. In telecommunications infrastructure, when a call traverses from point A to point B, it typically passes through multiple network segments.

It is the service that handles the ingress of voice traffic into destination networks, managing the interconnection between carriers, protocol conversion (TDM to VoIP or vice versa), and the delivery of calls to their final endpoints, whether that's a PSTN landline, mobile network (GSM/CDMA), or an IP-based system.

How does Voice Termination work?

When a call is initiated, it passes through an originating carrier and then needs to be terminated by connecting to the destination network. Voice termination providers like IDT Express act as the bridge between different telecommunications networks, routing calls efficiently and reliably to their final destinations across the globe. This process involves converting voice signals into data packets (in VoIP scenarios), routing them through optimal pathways, and ensuring quality connections with local carriers in the destination country or region.

The Gold plan delivers strong quality of service at competitive rates, suited for calling card services, pinless calling, or inmate calling providers. IDT Instant provides market-based pricing with quality routing, making it a good fit for UCaaS, CPaaS, and cloud PBX providers. Additionally, IDT Express can build custom routing solutions for businesses with unique voice termination requirements.

How do I get started with IDT Express Voice Termination?

Businesses can start with a 14-day free trial that includes a $25 bonus credit without requiring a credit card. The onboarding process involves providing company information, contact details, and the switch IP, after which a regional sales manager assists with setup. This allows businesses to test the service and experience the platform before committing to a paid plan.

What features are available via the IDT Express portal?

The IDT Express portal offers full self-service control, including ordering and provisioning DIDs, updating IP addresses, and configuring routing options. Users can select local Points of Presence (POPs) to optimize routing based on geography, manage voice termination routes in real-time, and make changes instantly. The portal streamlines both configuration and monitoring, giving businesses the flexibility to manage their voice traffic efficiently.

Which types of businesses benefit most from IDT Express Voice Termination?

IDT Express is suited for wholesale VoIP providers that require large-scale, high-capacity outbound termination, UCaaS and CPaaS companies seeking cost-effective and reliable routing, and calling card or pinless services that need stable, high-quality connections. It also supports businesses that require DIDs combined with voice termination, enabling unified management of communications through a single portal.

What are the billing and contract terms?

Rates for voice termination are billed per minute, with billing increments outlined in the rate notifications. IDT Express reserves the right to adjust rates or destination codes, generally taking effect immediately with notification. For services involving virtual DIDs, there is a minimum one-month service term with automatic monthly renewal until canceled. Fees such as setup, monthly recurring, and usage charges are billed in advance and may be prorated if applicable.

What support and reliability does IDT Express provide?

IDT Express offers 24/7 global support and dedicated account management to ensure businesses have continuous access to assistance whenever needed. Their global network of direct and exclusive routes provides high capacity and reliability for voice termination, allowing enterprises to manage large call volumes with confidence. Businesses can also configure routing, monitor traffic, and manage DIDs through the self-service portal, making it easier to maintain service quality and continuity.

Can I customize routing for specific destinations?

Yes. IDT Express allows customers to configure custom routing for specific countries, regions, or destinations. This includes selecting preferred carriers, prioritizing Tier‑1 routes, and applying least-cost routing rules. Custom routing can help optimize call quality, reduce costs, and meet regulatory or SLA requirements in different markets.

What happens if I exceed my expected call volume?

IDT Express can accommodate scaling needs. If traffic exceeds planned volumes, the platform automatically manages excess traffic using available routes to maintain call quality. Customers can also work with account managers to expand capacity, adjust routing, or implement load balancing for high-volume campaigns.

Why should I choose IDT Express over other termination providers?

IDT Express combines a global network of direct and exclusive routes with real-time self-service control, flexible pricing, and strong technical support. Customers benefit from high-quality call delivery, extensive routing options, and the ability to manage both DIDs and voice termination in a unified portal.
