Direct Answer (TL;DR)
Brilo AI supports using your own phone numbers for outbound calls when your telephony provider routes outbound caller ID or SIP trunking through the Brilo AI platform. This is typically done by forwarding or routing calls through a SIP endpoint or carrier-level forwarding so Brilo AI voice agents present your chosen outbound caller ID. You must work with your carrier (for example, Twilio or your SIP trunk) to authorize caller ID and routing. Brilo AI can validate routing logic and capacity during onboarding.
Can we use our Twilio numbers with Brilo AI? Yes — when your provider routes outbound calls to Brilo AI and permits presentation of your caller ID, Brilo AI can place outbound calls using your numbers.
Will Brilo AI show our number as caller ID? When configured via your telephony provider or SIP trunk, Brilo AI can present your outbound caller ID per carrier rules.
Is this BYON (bring your own number)? Yes — bring your own number (BYON) is the common term for this setup and Brilo AI supports it when routing and forwarding are configured.
Why This Question Comes Up (problem context)
Buyers ask this because outbound caller ID, brand recognition, and regulatory traceability affect customer response rates and compliance. Enterprises in healthcare, banking, and insurance want to know whether they keep existing numbers, how caller ID is controlled, and what carrier-level changes are required. They also need clarity on caller reputation, callback routing, and whether Brilo AI can meet telephony and compliance constraints.
How It Works (High-Level)
When you enable use of your own phone numbers, your telephony provider forwards or routes outbound calls to Brilo AI’s platform or a configured SIP endpoint so the Brilo AI voice agent can place calls that display your outbound caller ID. Brilo AI voice agent capabilities include handling call setup, script execution, and post-call events while your carrier remains the source of the phone number and numbering authority. Call flows, retries, and voicemail behavior are controlled by the Brilo AI workflow while the telephony layer controls number presentation and PSTN connectivity.
Bring your own number is the configuration where your carrier routes calls through Brilo AI so outbound caller ID is your number.
A SIP endpoint (SIP trunk) is the network address your carrier or SIP provider uses to hand off calls to Brilo AI for processing.
Outbound caller ID is the phone number presented to the callee and is controlled by your telephony provider subject to carrier policies.

Guardrails & Boundaries
Brilo AI requires your telephony provider to authorize number presentation; Brilo AI cannot force a carrier to present a number if the carrier blocks it.
Brilo AI follows the routing and call-handling logic you configure in workflows but will not change carrier-level caller ID rules or numbering ownership.
Regulatory controls (for example, TCPA lists or DNC rules) must be enforced in your outbound workflow; Brilo AI provides compliance controls in the platform but relies on you to supply and maintain compliant lists and opt-outs.
Do not route emergency (E911) or other regulated services through BYON configurations that are not supported by your carrier and local regulations.
Call routing policy is the rule set you configure that determines which number is used, when retries happen, and when a session escalates to a human—these policies should reflect both platform workflow rules and carrier constraints.

Applied Examples
Healthcare: A clinic routes its existing patient appointment line through Brilo AI so reminder calls show the clinic’s known number. The clinic provides Brilo AI with a verified caller ID and a maintained patient contact list; Brilo AI runs reminder scripts and offers callback scheduling while ensuring the clinic’s opt-out rules are enforced.
Banking / Financial services: A bank uses its customer-service numbers for outbound fraud-alert calls. The bank configures its SIP trunk to hand off calls to Brilo AI and ensures the bank’s caller ID and callback routing are preserved; Brilo AI reads alert scripts and, when configured, offers verification steps before sharing account details.
Insurance: An insurer uses its policy renewals number for outbound outreach; calls originate from the insurer’s number and Brilo AI manages retries, voicemail handling, and transfer to live agents as configured.
Note: Examples describe typical configurations. You must validate your carrier’s policies and internal compliance before routing sensitive healthcare, banking, or insurance calls.
Human Handoff & Escalation
Brilo AI workflows can escalate calls to a human agent or another workflow when conditions are met (for example, a caller requests a live agent or a verification step fails). Typical handoff methods include warm transfer with session context or cold transfer depending on carrier capabilities and whether agent systems accept session context. To preserve the original outbound number for callbacks, ensure your routing model supports return paths to your CRM or agent desktop. Brilo AI can trigger a callback, create a ticket in your CRM, or call an agent endpoint based on your routing policy.
Setup Requirements
Provide a verified list of the phone numbers you want to use and confirm ownership with your carrier.
Configure your telephony provider to forward or route outbound calls to Brilo AI’s SIP endpoint (or carrier handoff) and enable caller ID presentation for those numbers.
Supply estimated peak concurrent calls and average call duration so Brilo AI can validate capacity and bandwidth needs.
Define the outbound workflow: scripts, retries, voicemail handling, and escalation conditions in Brilo AI’s campaign configuration.
Test end-to-end with a small pilot group, verify caller ID presentation, voicemail behavior, and human handoff before full production rollout.
Maintain and supply compliance lists (DNC/TCPA opt-outs) to Brilo AI or integrate them via your CRM/webhook endpoint so outbound filters apply in real time.

Business Outcomes
Using your own phone numbers with Brilo AI preserves brand recognition and reduces missed callbacks, which can improve answer rates and customer trust. Enterprises retain control of numbering and compliance while Brilo AI handles conversational flows, retries, and after-hours coverage. This model centralizes call logic in Brilo AI while preserving existing telephony contracts and caller reputation.
FAQs
Do I need to transfer number ownership to Brilo AI?
No. Typically you do not transfer ownership; you instruct your carrier to route or forward calls to Brilo AI’s SIP endpoint or handoff. Brilo AI processes calls while your carrier remains the number owner.
Can Brilo AI spoof or alter caller ID?
Brilo AI will present the caller ID that is authorized by your carrier and carrier policies. Brilo AI cannot override carrier-level restrictions on caller ID presentation.
How long does setup take?
Setup time depends on your carrier, number verification, and complexity of workflows. A simple pilot with a single number can often be validated faster than a multi-number enterprise rollout that requires SIP trunking and capacity planning.
Will callbacks go to Brilo AI or to our agents?
Callbacks follow the routing policy you configure. You can route callbacks back to Brilo AI workflows, to your CRM, or to live agents depending on your integration and routing choices.
What if our carrier doesn’t support SIP trunking?
If SIP trunking is not available, work with your provider to enable an approved handoff method (for example, carrier-level forwarding). Brilo AI can validate routing options during onboarding.
