FreeSWITCH vs Voicent

FreeSWITCH is an open-source framework for real-time voice and video communications. It can route calls, bridge video, transcode media, and connect protocols, and is designed for use in carriers, contact centers, and communication products. Its Event Socket exposes call control, channel management, and internal events to external processes over TCP. Integrations include HTTP backends, embedded Lua, Perl, Python, JavaScript, Java, and SignalWire connectivity. The mod_signalwire module connects to SignalWire for inbound and outbound PSTN calling over a persistent WebSocket session. Linux installation guidance covers Debian and Ubuntu using SignalWire packages or a source build. A free SignalWire account is required to access packages and downloads. FreeSWITCH is licensed under MPL 2.0 and can run in production at no cost; self-hosting requires dedicated resources to maintain on-premises infrastructure. The open-source edition has community support, while FreeSWITCH Pro offers commercial support, hardened builds, priority patches, and commercial modules including answering machine detection and licensed G.729 Annex A encoding and decoding.

Voicent develops software for automated voice, email, and text communication, with point-and-click controls for sharing information and exchanging ideas. Its hosted service runs in a browser and can be accessed from computers, phones, and tablets. Cloud plans include call-center features such as agent dashboards, predictive dialing, and campaigns. Cloud calling covers the USA and Canada; on-premise software supports worldwide use with local phone and text services and requires Windows. Voicent says its cloud service has no contact limit and allows unlimited contact imports without extra fees. Calls are billed from pickup to hang-up, with a 30-second minimum followed by six-second increments. Features include call recording, voicemail drop, and dialing modes such as predictive, progressive, preview, click-to-call, and alternate phone dialing. CRM integrations include Salesforce, SugarCRM, Zoho CRM, MySQL, and Voicent CRM. The service lists a free plan, paid options from $19/mo, and a 30-day trial. Standard support is available weekdays from 8am to 5pm PST, excluding holidays or closures.
