VitalPBX engineer to speak at ClueCon 2026 on carrier-grade telephony

VitalPBX will be represented on stage at ClueCon 2026 in Chicago, where engineer Joseph Montes will present a technical session on building Class 4 and Class 5 telephony environments with FreeSWITCH and SignalWire. The appearance underscores VitalPBX’s focus on carrier-scale infrastructure as the open-source PBX market pushes deeper into real-time communications and voice AI.

Why it matters: - VitalPBX is using ClueCon 2026 to showcase technical depth in carrier-grade telephony, a core need for MSPs, ITSPs and service providers scaling beyond single-site PBX deployments. - The session puts VitalPBX in front of engineers and carriers working on VoIP, SIP trunking, carrier billing and voice AI infrastructure.

What happened: - VitalPBX announced that engineer Joseph Montes will present at ClueCon 2026 in Chicago. - Montes’s session is titled "Making a Class 4/Class 5 Environment Using FreeSWITCH w/ SW." - The talk is scheduled for Tuesday, August 11, 2026, from 4:30 PM to 5:00 PM CT. - ClueCon 2026 runs August 10–13 in Chicago and is hosted by SignalWire.

The details: - Montes will explain how to build a combined Class 4 and Class 5 telephony environment. - Class 4 refers to the wholesale, carrier-to-carrier routing layer. - Class 5 refers to the end-user, subscriber-facing services layer. - The session will focus on using FreeSWITCH in coordination with SignalWire. - ClueCon’s technical program includes sessions on FreeSWITCH internals, SIP security, carrier billing and emerging voice AI architecture. - VitalPBX is an open-source PBX platform built on Asterisk. - VitalPBX won the 2026 INTERNET TELEPHONY Product of the Year Award. - The platform’s Multi-Tenant plan supports multiple independent PBX environments and the carrier trunk traffic that feeds them on a single server. - VitalPBX positions that plan as an alternative to one-server-per-instance deployment models. - The company says its pricing model charges per feature and plan rather than per user or extension. - VitalPBX serves MSPs, ITSPs, system integrators, call centers and IT administrators. - The company lists more information at vitalpbx.com.

Between the lines: - VitalPBX is signaling that its product roadmap and its engineering team are aligned around larger, more complex deployments. - A conference talk on Class 4/Class 5 architecture suggests the company wants to be seen as more than a software vendor and more as an infrastructure expert. - The ClueCon slot also gives VitalPBX visibility inside the open-source communications community that shapes carrier and real-time voice tooling.
