Announcing Zentrunk Outbound — Enterprise-Grade SIP Trunking

We’re excited to announce the general availability of Zentrunk, Plivo’s enterprise-grade SIP trunking platform.

SIP trunking has been around for many years, but many enterprises that need to connect to the PSTN network from their telecom infrastructure still use old legacy connections or providers. In part, that’s likely because SIP trunking used to involve long manual provisioning times, restricted capacity, limited feature sets, and extended contract negotiations.

Zentrunk is a modern approach to SIP trunking that enables instant provisioning of SIP trunks, virtually infinite cloud scale, and global reach, all powered by an intelligent routing engine on the back end.

If you have your own telecom infrastructure, whether it’s a cloud-based communications platform or on-premises equipment, Zentrunk is for you. Zentrunk enables you to connect your existing telecom infrastructure to the PSTN without any restriction on the number of concurrent calls. Simply put, Zentrunk provides you with PSTN connectivity across 200 countries with zero contracts, pay-per-call pricing, and unlimited capacity.

Unique benefits of Zentrunk

Whether you’re looking to add a high-capacity carrier that can support your growth or just add a reliable cloud-based trunk to backstop your existing setup, Zentrunk gets you started instantly.

Global coverage: You can connect with customers over phone calls without having to deal with individual telecom carriers in 200+ locations.

Scalability: Zentrunk lets you make unlimited concurrent calls, so you can scale your business phone system without worrying about capacity planning or channel limits, and extend your on-premises capabilities to the cloud and keep all your business logic.

High quality: Zentrunk’s intelligent call routing engine ensures that all of your calls are routed using a local carrier based on real-time quality metrics including average call duration (ACD) and answer seizure ratio (ASR). Zentrunk has points of presence (PoP) across seven regions (California, Virginia, Frankfurt, Mumbai, Singapore, Sydney, São Paulo) across five continents to ensure that you experience low latency and high voice quality.

Security: Your calls can connect securely with IP authentication and credential-based validation. Zentrunk offers Transport Layer Security (TLS) for signaling encryption and Secure Real-time Transport Protocol (SRTP) for media encryption.

Transparent pricing: Create trunks with unlimited channels and no minimum commitments. Pay for voice minutes only. Pay by standard billing intervals of six seconds in US and Canada and one second in most countries. Make your billing and reporting simpler, so you have better visibility into what you’re spending on telecom and have fewer vendors to manage.
