Direct Answer (TL;DR)
Yes — Brilo AI can be configured to integrate with 3CX phone systems when 3CX is run as a SIP-enabled PBX and your network and dial plan are provisioned to accept a SIP trunk or SIP gateway from Brilo AI. Integration typically uses SIP trunking or a certified SIP gateway, requires SIP credentials (or trunk registration), and needs firewall, codec, and signaling settings aligned before calls flow. Where native connectors are not available, Brilo AI can connect through standard SIP interfaces and then forward call events to your CRM or webhook endpoints for call logging and case creation. For enterprise deployments, plan testing for call routing, DTMF, and secured media (SRTP/TLS) before moving to production.
Can Brilo AI connect to 3CX phone system? — Yes; when 3CX is configured to receive a SIP trunk from Brilo AI and network/DID routing are provisioned, Brilo AI can handle inbound/outbound calls via SIP.
Will Brilo AI register to a 3CX PBX? — Often yes; Brilo AI can be configured to register as a SIP trunk endpoint or send calls via a gateway when SIP registration is supported.
Can Brilo AI work with on-prem 3CX appliances? — Yes; on-prem 3CX deployments can integrate if your network allows SIP signaling and media between Brilo AI and the 3CX system.
Why This Question Comes Up (problem context)
Enterprises running 3CX ask this because 3CX is a common PBX choice and teams want to add conversational automation without replacing telephony infrastructure. Buyers want to know whether Brilo AI voice agent requires a cloud PBX, whether SIP credentials or trunking changes are needed, and how call routing and CRM logging will behave. IT, security, and contact center teams need clarity on network changes, codec support, and the handoff model to internal agents.
How It Works (High-Level)
Brilo AI connects to phone systems like 3CX by using standard SIP call signaling and media flows. In a typical configuration Brilo AI is provisioned as a SIP trunk or SIP endpoint to the 3CX dial plan; when calls arrive at 3CX they are routed to the Brilo AI voice agent, which answers, conducts the scripted interaction, and then either completes the call or routes it back to a human extension. Brilo AI captures call events, transcribes interactions, and can post structured call data to your CRM or webhook endpoint in real time.
In Brilo AI, 3CX integration is a configuration where Brilo AI connects to a SIP-enabled PBX to send and receive calls through SIP trunking.
For routing examples and CRM mapping patterns, see Brilo AI’s integration examples such as the Brilo AI integration with Salesforce which shows how call events map to CRM records.

Guardrails & Boundaries
Brilo AI is designed to operate within explicit telephony and workflow guardrails you set. Do not route calls to Brilo AI from 3CX unless:
SIP signaling and media are tested across your firewall and NAT topology.
Required codecs and DTMF methods are validated for IVR and payments (if used).
Clear escalation rules exist for sensitive or ambiguous requests.
In Brilo AI, an escalation rule is a configured condition that transfers a call to a human agent or alternate workflow when confidence, content, or business rules require human review. Brilo AI will not access internal systems or data unless you explicitly configure those connections and consent flows. For answer quality controls and CRM mapping patterns, consult integration setup guides such as the Brilo AI integration with HubSpot.
Applied Examples
Healthcare example
A hospital front desk runs 3CX for on-prem telephony. Brilo AI voice agent takes routine appointment calls, confirms patient identifiers, and creates a follow-up record in the hospital’s scheduling system via a webhook. Complex clinical questions are automatically routed to a human scheduler.
Banking / Financial services / Insurance example
An insurance contact center keeps 3CX as the dial plan. Brilo AI answers policy status calls, authenticates callers using pre-configured challenge questions, logs the call to the insurer’s CRM, and escalates suspected fraud or claims to a live specialist based on scripted triggers.
Note: Do not interpret these examples as legal, medical, or compliance advice. Check your regulations and internal policies before automating sensitive conversations.
Human Handoff & Escalation
Brilo AI supports multiple handoff strategies with 3CX:
Warm transfer: Brilo AI calls and introduces the customer to a live agent extension on 3CX and then bridges the call.
Cold transfer: Brilo AI forwards the call to a target extension or external number and releases.
Conference transfer: Brilo AI can add a live agent to an active call so the agent can listen and then take over.
Handoff behavior is controlled by your Brilo AI workflow rules and the 3CX dial plan. Ensure transfer codecs and media negotiation are tested so audio quality and DTMF functionality remain intact during transfers.
Setup Requirements
Gather SIP credentials: Provide Brilo AI with your SIP trunk credentials or endpoint details (username/password or trunk IP and port).
Verify DIDs and routing: Assign which DID(s) will route to Brilo AI and update 3CX inbound rules accordingly.
Open network ports: Configure firewall and NAT to allow SIP signaling and media (and enable SRTP/TLS if you require encrypted media).
Validate codecs: Confirm supported codecs and DTMF methods between Brilo AI and 3CX.
Configure CRM/webhooks: Point Brilo AI to your CRM or webhook endpoint for call logging and case creation.
Test call flows: Run test calls for IVR navigation, transfers, and voicemail handoffs before production cutover.
Monitor and iterate: Review call logs and transcription quality to adjust prompts and escalation thresholds.
For CRM mapping examples and call-data workflows, see integration references such as the Brilo AI integration with Zoho and the Brilo AI integration with Microsoft Dynamics 365.
Business Outcomes
When configured correctly with 3CX, Brilo AI voice agent can:
Reduce live agent load for routine inquiries by handling common call flows.
Improve call logging and CRM data capture by posting structured call events in real time.
Provide consistent initial screening and routing so higher-value calls reach skilled agents faster.
These outcomes depend on proper SIP configuration, clear escalation rules, and ongoing tuning of prompts and intent thresholds.
FAQs
Does Brilo AI require a cloud PBX to integrate with 3CX?
No. Brilo AI can integrate with on-prem or cloud-hosted 3CX systems provided the PBX exposes SIP trunking or gateway endpoints and network/firewall rules permit SIP signaling and media.
What network settings must my team change in 3CX?
You will typically need to add or modify inbound routing to send selected DIDs to the Brilo AI SIP trunk, ensure NAT and SIP ALG settings are compatible, and open ports for SIP and RTP. Work with your network and 3CX administrator to validate these settings.
Can Brilo AI support encrypted media (SRTP) and TLS signaling?
Brilo AI can be configured to use secure signaling and media when both sides support SRTP and SIP over TLS; confirm cipher and certificate requirements during provisioning and testing.
How does Brilo AI handle voicemail or missed calls on 3CX?
Voicemail handling depends on your 3CX dial plan. Brilo AI can be configured to answer and create follow-ups or let 3CX handle voicemail and then ingest voicemail metadata or recordings via an integration point if you provide the storage or webhook.
Will call recordings be stored in Brilo AI?
Call recording behavior is configured per deployment. Brilo AI can produce transcripts and call metadata for CRM logging; storage location and access policies are defined during setup and must comply with your organization’s policies.
