If you run a phone system for clients or for your own company, you know the drill. Calls you never have time to review. SIP floods hammering your firewall. A user complains about choppy audio and you have no quick way to see why.
VitalPBX 4.5.5 R1 tackles all three. Released on November 10, 2026, this update brings AI-powered call insights to the CDR Portal, tighter intrusion protection, real-time latency monitoring for PJSIP endpoints, new device support and an updated Asterisk core.
Here is everything that changed, what it means for your deployments, and how to get it.
AI-Powered Call Insights in VitalPBX 4.5.5
The biggest headline in VitalPBX 4.5.5 is AI that helps you understand calls without listening to every recording.
Call transcription and sentiment summaries in the CDR Portal. You can now get a transcript of a call and an AI-generated sentiment summary right from the CDR Portal. Supervisors and managers can review conversations in seconds and spot unhappy callers before they turn into lost customers.
Context-aware AI Phone Agents. AI Phone Agents now recognize the dialed number (DID). That means one system can greet callers with the right brand or business name depending on which number they called. For MSPs and multi-brand companies, that is a big deal. Caller information is also preserved when the AI Agent transfers the call to a human agent or a queue, so nobody has to ask “can you repeat your name?”
Expanded speech recognition. VoiceHub and AI Tools now support the gpt-transcribe speech-to-text engine, which is also the new default for VoiceHub transcription. AI Assistants have also been migrated to OpenAI’s Responses API, for continued compatibility and better handling of multi-turn conversations.
Stronger Security With Less Disruption
Security is a major part of this release. Three changes stand out:
- Better protection against SIP floods. UDP traffic from banned IP addresses is now blocked before it reaches Asterisk, including traffic tied to existing connection tracking states. Attack traffic stops at the door instead of eating resources.
- Automatic protection for custom ports. Intrusion protection now follows the SIP, HTTP and WebRTC ports you configure in the GUI. Change a port, and protection follows it. No more mismatches between your PBX and your ban rules.
- Accurate client IP detection. WebRTC and web phone connections behind reverse proxies can now report the real public client IP. That makes logs, troubleshooting and bans far more reliable.
The result: stronger protection while your telephony services keep running smoothly.
Better Monitoring and Visibility
PJSIP endpoint monitoring with RTT. The PJSIP Endpoints report now shows color-coded round-trip time (RTT) indicators. You can spot latency problems at a glance, across every device. Click a status badge and a device details window opens with live RTT, remote IP address, User Agent, and a link to the device’s web interface when it is on a local network.
Sonata Switchboard improvements. Queue monitoring is more responsive, with better handling of disconnected callers, queue positions and agent call status across multiple queues. Supervisors get a cleaner, more accurate live view.
More Devices, Easier Provisioning
VitalPBX 4.5.5 R1 expands device compatibility:
- Yealink T85W expansion module
- VTech CTM-S2212 hospitality phone
- 15+ additional Intelbras IP phone models across the TIP and V-series
More supported hardware means faster rollouts and fewer manual configurations for your installers.
Performance, Stability and Reliability
Under the hood, this release:
- Updates Asterisk to 20.22.0
- Optimizes event processing between Asterisk and the VitalPBX GUI to reduce resource usage
- Improves handling of call recording folders in multi-tenant environments that use network-mounted storage

Why This Release Matters for MSPs and Integrators
Every change in 4.5.5 R1 saves you time on something you already do: reviewing calls, defending servers, chasing latency complaints and provisioning phones. And it all comes on the same plan-based pricing, with no per-user or per-extension fees. Add 10 users or 5,000; your license cost does not change.
That is part of why VitalPBX earned the 2026 INTERNET TELEPHONY Product of the Year Award.
