What is Flowroute
Flowroute is a cloud communications platform focused on programmable voice services, including SIP trunking, phone numbers (DIDs), and voice calling APIs. It is used by software teams, contact center operators, and IT/telecom administrators to embed PSTN connectivity into applications or to connect PBX/UC systems to the public telephone network. The product emphasizes carrier-grade telephony primitives (numbers, routing, SIP, and call control) rather than a broad omnichannel messaging suite. Flowroute operates as part of Intrado’s communications portfolio.
Strong SIP trunking focus
Flowroute provides SIP trunking and PSTN connectivity designed for integrating PBX/UC platforms and voice applications. This is well-suited to organizations that primarily need reliable inbound/outbound calling rather than a broad customer messaging stack. The offering aligns with telecom-centric use cases such as call routing, termination, and number management. For teams comparing cPaaS options, this specialization can reduce complexity when voice is the main requirement.
Programmable voice and numbers
Flowroute offers APIs for managing phone numbers and enabling voice calling workflows. Developers can provision and manage DIDs and configure routing without manual carrier processes. This supports use cases like provisioning numbers per customer/region and automating telephony operations. The API-first approach fits engineering-led implementations and platform integrations.
Operational controls for telephony
The platform includes administrative capabilities for managing trunks, numbers, and routing configurations. These controls help telecom/IT teams standardize how PSTN connectivity is configured across environments. It supports common operational needs such as inventory management for numbers and configuration changes without vendor tickets. This is valuable for organizations running multi-tenant or multi-site voice deployments.
Limited omnichannel breadth
Flowroute is primarily oriented around voice/PSTN services rather than a full omnichannel communications suite. Organizations seeking a single platform for SMS, chat, email, and in-app messaging may need additional vendors or components. This can increase integration and vendor-management overhead. Buyers should validate whether required channels beyond voice are supported natively.
Developer and telecom expertise needed
Implementations typically require familiarity with SIP, telephony concepts, and API-based provisioning. Non-technical teams may find setup and troubleshooting more complex than turnkey contact-center or messaging products. Ongoing operations can involve telecom-specific monitoring and configuration management. This can lengthen time-to-value for organizations without in-house voice expertise.
Feature depth varies by use case
Flowroute’s strengths are in core telephony primitives, but advanced application-layer features (for example, higher-level conversation orchestration or built-in agent tooling) may not be the focus. Teams building complex customer engagement flows may need to assemble additional services. This can shift more responsibility to internal development and architecture. Prospective customers should map required features to what is provided at the API and admin-console layers.
Plan & Pricing
Pricing model: Pay-as-you-go Free tier/trial:

(The Messaging Fees page lists a "Platform Free Trial" use case priced $0.00 for pre‑approved CSPs, but this appears specific to carrier/TCR use‑case registration rather than a general trial offer.)
