Simon Telephonics is an IP communications and open-source VoIP services business operated by Bill Simon. It focuses on sales, installation, configuration, monitoring, maintenance, and troubleshooting for FreePBX, PBXact, Asterisk, FreeSWITCH, and Microsoft Teams. Rather than a traditional email, SMS, or CPaaS API platform, it is a specialist integration and operations provider for enterprise voice PBX systems.
In terms of channels, the website’s information is mainly centered on voice VoIP and Microsoft Teams voice integration; there is no visible bulk email or SMS capability. Its Teams Calling for FreePBX solution uses Direct Routing and a self-hosted Teams Gateway to let the Teams desktop, mobile, and web clients function as FreePBX extensions. Businesses can keep their existing FreePBX features and preferred SIP provider without turning Teams into the sole PBX. On the security side, the solution states that Teams calls use TLS and SRTP, and connect to the PBX through a single secure SIP trunk, reducing the need for VPN access for mobile users.
Pricing disclosure is limited. Microsoft Phone System licensing must be obtained by the organization through a Microsoft partner or reseller; if the plan does not include this feature, the listed MSRP is USD 8 per seat. Simon Telephonics’ Teams Gateway service is offered as a subscription customized by organization size and requirements, while PBX installation, maintenance, and diagnostic fees are also not publicly listed. For integration, Microsoft Phone System licensing and PJSIP are required, along with configuration in the Microsoft Teams admin center and on the FreePBX/Asterisk/FreeSWITCH side. The technical barrier is clearly higher than with plug-and-play cloud communications APIs.
Its strengths are a clear technical focus, experience with open-source PBX, SIP, and Linux operations, and its status as a Sangoma Silver Partner and Microsoft Partner, with support for AWS Marketplace AMIs as well. It is a good fit for companies already using FreePBX/PBXact that want to turn Teams into a softphone extension, or that need SIP packet captures, server troubleshooting, and hosted phone-system maintenance. The drawbacks are that public information lacks details on SLA, call quality, concurrency, geographic coverage, payment methods, and compliance certifications. Pricing also requires consultation, making procurement predictability only average.
Simon Telephonics is better suited to SMBs, call centers, or technical teams that already have a PBX foundation but lack VoIP expert support. It is not a good fit for developers looking for standardized SMS, email, or global voice APIs. Information on access from mainland China, payment, and local compliance is not disclosed. Actual use would also depend on the network connectivity of Microsoft 365, SIP carriers, and cloud platforms. For deployment in China, it is advisable to evaluate local cloud communications or enterprise telephony alternatives at the same time.
