VoIP.ms API gives developers programmatic access to VoIP.ms accounts and telephony features. Its REST/JSON interface has more than 100 methods, and a SOAP API with WSDL is also available. Teams can search, order, configure and cancel phone numbers, manage subaccounts, and work with routing, IVRs, ring groups and queues. It is suited to developers, resellers, managed-service providers and businesses that want to manage communications through APIs across web, iOS and Android environments.

The API's breadth is its clearest strength: beyond number and routing management, methods cover call detail records, incoming and outgoing call recordings, SMS and MMS, fax, E911 and local number portability workflows. Phone numbers can be searched and ordered through the API, while SIP-based calling, recording and routing are handled through the broader VoIP.ms platform. SIP, IAX2 and Microsoft Teams are listed integrations. This makes the service a fit for teams coordinating multiple telephony tasks, rather than those looking only for a narrowly focused voice call-control API.

Pricing is organized around pay-as-you-go services, with listed plan types for local voice numbers, outbound local calls, inbound local calls and call recording. The product has no free plan. Inbound calls to DID numbers, local call termination and recording of incoming and outgoing calls are covered by those offerings. Support channels include email, chat, phone, tickets and documentation. Choose VoIP.ms API when account, number and routing administration across a broad set of communication features is the goal; consider another option if the main requirement is explicitly documented voice call control rather than wider telephony management.
