The Vonage network
To deliver a superior voice experience, our infrastructure is supported by a redundant ring architecture of 25 points-of-presence and 10 data centres throughout the USA. In addition, because we are a carrier, we have direct peering connections to all major carriers in the USA, eliminating intermediaries and improving voice quality further.
Built for scale
We terminate over 15 billion minutes of global voice traffic annually to landline and mobile phones, which means our voice network will scale to give your application the capacity and high availability you expect from a leading voice platform.
Global connectivity
Our platform is connected directly to tier 1 network providers all over the globe. Not only does this mean we’re using high-quality voice circuits, but this also eliminates the number of hops to deliver international calls, improving the overall voice experience for your end-users.
High quality, globally
We’re using high-quality voice circuits to deliver your calls with high Mean Opinion Scores (MOS) and Answer-Seizure Ratios (ASR), particularly important when delivering latency-sensitive use cases such as voice anonymisation.
Feature rich voice connectivity
In order to deliver quality voice applications that engage end-users, you need a platform that supports feature-rich voice connections, including support for Caller Line Identity (CLI) and DTMF.
CLI and DTMF
Caller Line Identity (CLI) allows end-users to see who is calling and, in particular, whether the caller is domestic or international. With our support for CLI and local numbers in more countries, you can engage users with a familiar calling experience. In addition, with our support for DTMF, you can deploy applications that require customers to interact with the keypad, such as IVR or conferencing.Voice Quality in action
Our customers rely on Vonage APIs to deliver great user experiences across an assortment of programmable solutions.
