3CX has shipped the most significant visual overhaul of its web client in the platform's history. V20 Update 9 Alpha redesigns Team view, navigation, the dialer, and nearly every screen users interact with daily — while adding enterprise-grade queue controls and the latest real-time AI voice models underneath.
For businesses running Hosted PBX or VoIP Communications on 3CX, this update changes how your team interacts with every call, queue, and chat — every day. Here is a full breakdown of what's new.
A Complete Visual Overhaul of the Web Client
Every view in the web client — Team, State, Chat, Call History, Contacts, Voicemail, and Settings — has been redesigned with a cleaner layout and improved usability. The aim was to reduce visual noise and make everyday tasks faster to reach.
Two new layout densities let users choose how much information to display at once:
Comfortable Mode
More whitespace between entries. Ideal for users who manage a smaller number of extensions and want a clear overview at a glance.
Compact Mode
Tighter rows show more extensions and active calls simultaneously. Built for call centres and reception desks monitoring large groups.
Dialer reworked for clarity
The dial pad has been redesigned to place and manage calls without unnecessary distractions. Number input, recent calls, and transfer controls are more logically grouped — fewer clicks to complete common actions.
Navigation simplified
The menu structure has been reduced, cutting the number of clicks required to move between sections. PWA (Progressive Web App) support has also been refreshed with a cleaner provisioning flow — install the 3CX web client as a desktop app in one step.
Queue Features Built for Real Call Centres
V20 Update 9 ships six new queue behaviours that give far more control over SLAs, hold experience, and how missed calls are handled. These are meaningful additions for any business running an inbound call operation.
Callback on Request
Callers can request a callback after hearing an announcement, instead of waiting on hold. Reduces call abandonment and keeps customers in control of their time.
Time-Based Escalation
Calls can escalate after a configured timeout — not just when all agents are unavailable. Set clear SLA thresholds and route callers to the next tier automatically.
Cumulative Ringing
Ring groups expand progressively — add agents in stages without stopping earlier ones from ringing. Ensures the fastest available agent answers without every desk ringing simultaneously from the start.
Comfort Prompt
Play one or more prompts to callers while they wait in the queue. Reduces perceived hold time and is a simple way to share business information or promotions.
Estimated Wait Time Announcements
Announcements are based on actual agent statistics rather than fixed estimates — giving callers a realistic wait time that builds confidence rather than eroding it.
No Answer Prompt
Configure a custom announcement before a call transfers to the No Answer destination — aligned with other routing behaviours for a consistent caller experience.
Running a contact centre or reception desk?
These queue features are already available on the 3CX platform that Sentire deploys and manages. Talk to us about configuring callback, escalation, and wait time announcements for your setup — the changes are made in the 3CX Admin Console, no additional licences needed.
Real-Time AI Voice: Faster Models, Better Responses
3CX's AI capabilities are built on real-time voice models — the engine behind features like the AI Receptionist and AI-assisted call handling. Update 9 upgrades the underlying models to significantly reduce latency and improve response quality during live calls.
gpt-realtime-1.5 — lower latency for live interactions
The new default real-time model improves latency and tool execution during live voice interactions — meaning the AI Receptionist responds faster and handles interruptions more naturally.
gpt-4.5 for async AI tasks
3CX has added support for gpt-4.5 for AI features that run outside the live call path — improving quality across use cases that don't require real-time response. Prompt handling improvements are also included, with further details to follow.
Further AI updates — including deeper integration with the AI Receptionist and omnichannel features — are coming in subsequent releases. The 3CX team has indicated this is an active area of development. More detail is available through the 3CX AI Features page and the 3CX Omnichannel page.
Other Improvements Worth Noting
Beyond the headline changes, Update 9 ships a set of operational and administrator improvements that affect day-to-day management of a 3CX system.
- User extension count in Admin Console — the number of user extensions is now visible directly in the Admin Console, making licence management faster.
- SMS API updates — added support for Bandwidth and Workato integrations, expanding SMS routing options beyond the existing carrier list.
- Custom VoIP Provider Template Builder — administrators can now build custom VoIP provider templates and store them in the system. This is particularly useful for organisations managing multiple SIP trunk configurations.
- Remote syslog — system events and audit logs can now be exported to external syslog systems (UDP, TCP, TLS, IMTLS), supporting compliance and monitoring workflows.
- Play Department Holidays Prompt — activated for all trunks, allowing holiday prompts to be configured on the trunk level without needing to activate the holiday script separately.
Update 9 is an Alpha release
Alpha releases are intended for evaluation on non-production systems only. If you manage a live 3CX deployment, wait for the stable V20 Update 9 release before upgrading. Sentire will communicate timing and upgrade guidance to all managed clients.
What This Means for Your Business Phone System
As a 3CX Silver Partner, Sentire deploys, manages, and supports 3CX for organisations across Kenya. Every update like this one is evaluated by our engineering team before it reaches managed clients — we test the changes, verify compatibility with existing configurations, and communicate clearly before any upgrade touches a production system.
Whether you are running a single-site office PBX or a multi-site deployment with call centre queues, the features in V20 Update 9 are worth understanding now so you can plan for them when the stable release ships.
Hosted PBX →
3CX cloud PBX, AI features, CRM integration, and omnichannel — managed by Sentire.
VoIP Communications →
SIP trunking, local carrier integration, and call quality management across Kenyan networks.
A question worth sharing with your IT team or office manager:
When did someone at your company last check whether your phone system's queue settings actually reflect how your business handles calls today? The callback and escalation features in 3CX Update 9 exist because most queue configurations are set once and never revisited. Share this post with whoever owns your phone system — it might be worth a 30-minute review.
