Direct Answer (TL;DR)

Yes — Brilo AI voice agent can connect to Asterisk-based systems when your Asterisk installation exposes a SIP interface or SIP trunk that Brilo AI can reach. Brilo AI supports SIP-based call routing and can be configured to accept or place calls through an Asterisk PBX using SIP trunking, SIP registration, or a SIP gateway depending on your network and security setup. Typical configurations require a reachable SIP endpoint, firewall/NAT allowances, and agreed codecs and signaling (SIP). Contact Brilo AI for an integration review to validate your Asterisk topology and security constraints.

Can Brilo AI connect to Asterisk? Yes. When your Asterisk server provides a SIP trunk or gateway, Brilo AI voice agent can be configured to route calls to and from Asterisk.

Can Brilo AI work with on‑prem PBX systems like Asterisk? Yes. Brilo AI can integrate with on‑prem Asterisk PBX via SIP trunking or a SIP gateway when network and security requirements are met.

Does Brilo AI require a public SIP trunk for Asterisk? Not always. Brilo AI can work with private SIP endpoints if you provide a secure, routable interface (for example, via a VPN, SIP over TLS, or an approved SIP gateway).

Why This Question Comes Up (problem context)

Many enterprise buyers run Asterisk as their PBX and need to know whether they can keep existing telephony infrastructure while adding Brilo AI voice agent capabilities. Questions typically focus on compatibility (SIP vs. PRI), call routing control, security (firewalls and NAT), codec support, and whether Brilo AI can hand off calls back into local agent queues. Banking, insurance, and healthcare teams ask specifically about maintaining compliance boundaries and local call recording policies when bridging to an external voice agent.

How It Works (High-Level)

When connecting to an Asterisk-based system, Brilo AI voice agent acts as a SIP endpoint or SIP trunk peer. Calls flow between Asterisk and Brilo AI over SIP signaling; media (audio) traverses RTP or secure RTP when configured. Brilo AI evaluates incoming call metadata, executes the configured voice agent script (IVR, NLU intent detection, or scripted prompts), and either resolves the call or routes it back to Asterisk for agent handling.

In Brilo AI, a SIP trunk is a configured SIP connection endpoint that allows Brilo AI to send and receive calls to your PBX over IP. SIP registration is the process for a SIP endpoint to authenticate and stay reachable for inbound call delivery. Related technical terms include SIP, SIP trunking, SIP registration, PBX, RTP, SIP gateway, and trunking.

Guardrails & Boundaries

Brilo AI should not be used to circumvent your organization’s telephony security or compliance requirements without an approved integration review. Brilo AI voice agent will only accept or place calls through Asterisk when you provide a reachable and authorized SIP interface and agree on signaling, media, and encryption options.

Human handoff is an explicit routing action that transfers the caller from the Brilo AI voice agent back into a live queue or a specific agent extension; it requires a routable target provided by your Asterisk configuration. Do not expose administrative Asterisk interfaces to the public internet. Limit Brilo AI connectivity to a controlled SIP trunk, a VPN, or a secured SIP gateway and agree on codecs and TLS/SRTP where required.

Applied Examples

  • Healthcare example: A hospital switchboard uses an on‑prem Asterisk PBX. Brilo AI voice agent is configured as a SIP trunk peer to answer after‑hours calls, schedule appointments, and triage basic inquiries. If the voice agent detects a clinician escalation, it triggers a handoff back to the on‑call nurse queue on Asterisk.

  • Banking example: A regional bank keeps customer account data behind its firewall on an Asterisk PBX. Brilo AI voice agent answers inbound loans and balance inquiries via a secured SIP trunk, authenticates callers using preconfigured prompts, and routes high‑risk authentication failures to live agents in the bank’s contact center.

Human Handoff & Escalation

Brilo AI voice agent workflows can hand off to a live agent or agent queue on Asterisk by issuing a SIP REFER, transferring to a specific extension, or placing a call back into your queue. Escalation triggers are configurable (for example, repeated NLU failures, sentiment thresholds, or caller requests). Handoff options include warm transfer (introducing context to the agent), blind transfer, or callback scheduling into your CRM. All handoff targets must be reachable from Brilo AI (SIP extension, queue, or gateway) and agreed during setup.

Setup Requirements

  1. Provide: Identify the Asterisk SIP endpoint details (SIP trunk IP/hostname, port, and peer credentials) or a SIP gateway that Brilo AI will use.

  2. Configure: Open and allow necessary ports (SIP signaling and RTP) or set up a VPN/SIP over TLS path to make the SIP endpoint reachable.

  3. Validate: Share codec, DTMF (RFC2833 or SIP INFO) settings, and SIP headers required by your Asterisk dialplan.

  4. Authorize: Create a dedicated SIP trunk/peer on Asterisk with limited privileges for Brilo AI traffic.

  5. Test: Execute call flows in a staging environment, verify IVR prompts, media quality, and handoff behavior.

  6. Iterate: Adjust routing and failover rules based on test results and call volumes.

Required items you must provide: your Asterisk SIP endpoint, network access plan (firewall/NAT/VPN), dialplan routing targets for handoff, and any caller authentication prompts or CRM integration endpoints (your CRM or webhook).

Business Outcomes

Connecting Brilo AI voice agent to your Asterisk system enables 24/7 automated handling for routine inbound calls, consistent caller experience, and fewer unnecessary live transfers. Organizations can protect existing telephony investments while adding conversational automation that routes complex cases to skilled staff. Operational benefits include improved call containment, predictable escalation behavior, and the ability to centralize voice agent logic without rebuilding the PBX.

FAQs

Does Brilo AI require changes to the Asterisk dialplan?

Minor dialplan changes are often required to route specific inbound DID or queue calls to the Brilo AI SIP trunk and to accept callbacks or REFER transfers. Exact changes depend on your current dialplan and handoff strategy.

Can Brilo AI connect over a VPN instead of a public SIP trunk?

Yes. Brilo AI can work with private network links (for example, a VPN or a secured SIP gateway) if you provide a routable and authenticated SIP endpoint reachable from Brilo AI.

What codecs and DTMF methods are supported?

Brilo AI supports common codecs and DTMF methods (for example RTP/DTMF via RFC2833); you should confirm exact codec lists and negotiate preferred media parameters during the integration review.

Will call recordings remain on-premises?

Recording location depends on your configuration and legal requirements. If you require recordings to remain on‑premises, discuss options to route media or recording control through your Asterisk environment during the integration review.

What happens if the SIP link to Asterisk fails?

You can configure fallback behavior: Brilo AI can play a failover message, queue the caller in an alternative route, or initiate a callback workflow. Define these behaviors during setup.

Next Step

  • Request a Brilo AI integration review with our engineering team to validate your Asterisk topology and security constraints.

  • Provide your Asterisk SIP trunk details and a staging test plan so Brilo AI can run a proof of concept.

  • Contact Brilo AI support or your account representative to schedule a technical onboarding call and test window.
