You have built your AI voice agent on OpenClaw. It understands your business, handles conversations naturally, and is ready to take real calls. But before it can talk to anyone, it needs one thing: a phone number. Knowing how to give OpenClaw an own phone number is the final step between a configured agent and a live, working AI receptionist that answers your business calls 24/7.
This guide covers every method for connecting a phone number to your OpenClaw voice agent — whether you want a brand new number, want to keep your existing business number, or prefer to start with simple call forwarding. By the end, your AI agent will have its own dedicated phone line ready to handle real conversations.
Why Your OpenClaw Agent Needs Its Own Phone Number
An AI voice agent without a phone number is like an employee without a desk. It exists, but no one can reach it. When you give OpenClaw an own phone number, you are creating a direct line between your callers and your AI agent. Here is what that unlocks:
- Inbound call handling: Customers, leads, and partners can call your agent directly. It answers on the first ring, 24 hours a day, 365 days a year.
- Outbound calling: Your agent can place calls to contacts — follow-ups, reminders, lead qualification, and more — from a real caller ID that recipients recognize and trust.
- Professional caller ID: Calls from your agent display your business number, not a random or blocked number. This dramatically improves answer rates for outbound calls.
- Call recording and analytics: Every call through the number is logged, transcribed, and analyzed in your OpenClaw dashboard.
- Compliance: A registered business number ensures your OpenClaw voice calls comply with TCPA, STIR/SHAKEN, and other telecom regulations.
Three Ways to Give OpenClaw an Own Phone Number
OpenClaw supports three approaches to phone number setup. The right choice depends on whether you already have a business number and how quickly you want to go live.
Option 1: Get a New Number from OpenClaw (Fastest)
The simplest way to give OpenClaw an own phone number is to provision a new one directly through the platform. OpenClaw partners with major telephony providers to offer local, toll-free, and international numbers that are ready to use in seconds.
Step-by-step:
- Open your agent's settings in the ClawHub dashboard.
- Navigate to the Phone Number section.
- Click "Get a New Number."
- Choose your number type:
- Local number: A number with your city or area code. Best for businesses that want to appear local to their customers. Callers are more likely to answer calls from a local area code.
- Toll-free number: An 800, 888, 877, or similar prefix. Best for national businesses or customer support lines where you want callers to reach you for free.
- International number: Numbers in other countries for businesses serving global markets. Available for 40+ countries.
- Search for available numbers. You can filter by area code, city, or even search for vanity patterns (e.g., numbers containing "CALL" or "HELP").
- Select your number and click "Activate."
- Your agent is now live on that number. Test it by calling from your phone.
Cost: Typically $1-$5 per month for the number itself, plus per-minute charges for calls. Toll-free numbers may cost slightly more. There are no setup fees.
Best for: New businesses, new use cases, teams that want to test quickly without touching their existing phone setup, and businesses that want a dedicated AI line separate from their main number.
Getting a new number is the fastest way to give OpenClaw an own phone number. Most users go from zero to live calls in under 5 minutes.
Option 2: Port Your Existing Business Number (Keep Your Number)
If you already have a business phone number that customers know and trust, you do not need to abandon it. Number porting transfers ownership of your existing number to OpenClaw's telephony infrastructure so your AI agent answers calls on the same number your customers have always used.
Step-by-step:
- Open your agent's settings and navigate to Phone Number.
- Click "Port an Existing Number."
- Enter the phone number you want to port.
- Provide your current carrier information:
- Carrier name (e.g., AT&T, Verizon, Vonage, RingCentral)
- Account number with current carrier
- Account PIN or password
- Authorized account holder name
- Service address on file
- Sign the Letter of Authorization (LOA) that OpenClaw generates. This is a standard telecom document authorizing the transfer.
- Submit the port request. OpenClaw handles the rest with your current carrier.
- Wait for porting to complete. During this period, your existing number continues working normally with your current carrier.
- Once the port completes, your number is live on OpenClaw and your AI agent starts answering calls.
Timeline: Number porting typically takes 7-14 business days for landline numbers and 1-4 business days for mobile and VoIP numbers. The timeline is largely controlled by the releasing carrier, not OpenClaw.
Cost: Most ports are free. Some carriers charge an early termination fee if you are under contract. The ongoing monthly cost for the ported number is the same as a new number ($1-$5/month).
Best for: Established businesses with a well-known phone number, companies replacing a human receptionist or answering service, and businesses that want a seamless transition where customers notice no change in the number they call.
Important considerations:
- During porting, your number is not interrupted. Calls continue flowing to your current carrier until the port finalizes.
- Once ported, your number is exclusively on OpenClaw. You cannot have it ring on both your old system and OpenClaw simultaneously. If you need that flexibility, use call forwarding instead (Option 3).
- You can port the number away from OpenClaw in the future if you decide to switch platforms. You own the number.
Option 3: Forward Calls from Your Current Number (No Changes Needed)
Call forwarding is the zero-risk way to give OpenClaw an own phone number while keeping your existing phone setup completely intact. You keep your current number and carrier, and simply forward calls to a new OpenClaw number.
Step-by-step:
- Get a new number from OpenClaw (see Option 1). This becomes your agent's direct number.
- Set up call forwarding on your existing phone system. The exact steps depend on your carrier:
- Landline: Dial *72 followed by the OpenClaw number (e.g., *72-555-123-4567). You will hear a confirmation tone.
- VoIP (RingCentral, Vonage, etc.): Log into your admin portal, find call routing or forwarding settings, and enter the OpenClaw number as the forwarding destination.
- Mobile: Go to Settings > Phone > Call Forwarding (iOS) or Settings > Call Settings > Call Forwarding (Android) and enter the OpenClaw number.
- Cloud PBX: Configure the forwarding rule in your PBX admin panel. Most support unconditional forwarding, busy forwarding, and no-answer forwarding.
- Test by calling your original number. The call should ring through to your OpenClaw agent.
Advanced forwarding options:
- Unconditional forwarding: All calls go to OpenClaw. Your agent handles everything.
- No-answer forwarding: Calls ring your team first. If no one picks up after 3-4 rings, the call forwards to OpenClaw. Great for using AI as a backup when staff are busy.
- After-hours forwarding: Forward to OpenClaw only outside business hours. Your team handles daytime calls; the AI covers nights, weekends, and holidays.
- Overflow forwarding: Forward to OpenClaw only when all your lines are busy. The AI handles call spikes without you hiring temporary staff.
Cost: The OpenClaw number costs $1-$5/month. Your existing carrier may charge a small fee for call forwarding (check your plan). There is no setup fee from OpenClaw.
Best for: Businesses that want to test OpenClaw without any commitment, companies that want AI handling only specific call scenarios (after-hours, overflow), teams transitioning gradually from human to AI call handling, and businesses under contract with their current phone provider.
Which Option Should You Choose?
Here is a quick decision framework:
- Testing or new project? Get a new number (Option 1). It takes 2 minutes and costs almost nothing. You can always port your main number later once you are confident in the agent.
- Replacing your current phone setup entirely? Port your number (Option 2). Your customers keep calling the same number, but now an AI answers instead of a human or voicemail.
- Want AI as a backup or for specific hours? Use call forwarding (Option 3). Keep your current setup for normal operations and let OpenClaw handle the overflow, after-hours, or specific call types.
Many businesses start with Option 1 or Option 3 for a trial period, then move to Option 2 once they see the results. This is the safest path because you validate the AI's performance before making any permanent changes to your phone infrastructure.
Setting Up Your Phone Number for Specific Use Cases
How you configure your OpenClaw phone number depends on what your agent does. Here are setup recommendations for the most common use cases.
AI Receptionist
For an AI receptionist that answers all incoming calls:
- Port your main business number (Option 2) or set up unconditional forwarding (Option 3)
- Configure business hours greetings ("Thank you for calling Sunrise Dental, how can I help you?")
- Configure after-hours greetings ("Our office is currently closed. I can take a message or help you schedule an appointment.")
- Set up call transfer rules so the AI can connect callers to specific team members when needed
Lead Qualification
For an agent that qualifies inbound leads or makes outbound qualification calls:
- Get a new local number (Option 1) with an area code matching your target market
- Register the number with STIR/SHAKEN for verified caller ID on outbound calls
- Connect your CRM so qualified leads are logged automatically
- For outbound, ensure you have proper consent documentation before initiating calls
Customer Support
For an AI agent handling customer support calls:
- Get a dedicated toll-free number (Option 1) or port your existing support line (Option 2)
- Set up no-answer forwarding from your existing number so the AI catches calls your team misses
- Connect your helpdesk (Zendesk, Freshdesk) so the AI can look up ticket history and create new tickets
- Configure escalation paths to route complex issues to human agents with full context
Dispatch Service
For an AI agent managing dispatch operations:
- Port your dispatch line (Option 2) or forward after-hours calls (Option 3)
- The number must be available 24/7 for emergency service requests
- Connect your dispatch software so the AI can check technician availability and assign jobs in real time
- Set up emergency escalation to call on-duty staff for urgent situations
Multi-Number and Multi-Location Setup
Businesses with multiple locations or departments often need more than one phone number. OpenClaw handles this seamlessly.
One Agent, Multiple Numbers
You can assign multiple phone numbers to a single agent. The agent identifies which number was called and adjusts its greeting and behavior accordingly. For example:
- Main office number: "Thank you for calling ABC Plumbing headquarters."
- North branch number: "Thank you for calling ABC Plumbing North."
- Emergency line: "ABC Plumbing emergency service, what is your emergency?"
All three numbers route to the same AI agent, but the caller experience is tailored to each line.
Multiple Agents, One Number
You can also route a single number to different agents based on conditions. For example, route daytime calls to your sales qualification agent and after-hours calls to your receptionist agent. The caller dials one number, but the AI that answers adapts to the situation.
Multi-Location Deployment
For franchise or multi-location businesses:
- Get a local number for each location (matching each area code)
- Configure location-specific greetings, hours, and routing rules
- Connect location-specific calendars and staff directories
- Manage all locations from a single ClawHub dashboard with consolidated analytics
Phone Number Best Practices for OpenClaw
These best practices help you get the most out of your OpenClaw phone number setup:
- Use a local area code for outbound calls. Local numbers get 30-40% higher answer rates than toll-free or out-of-area numbers. If you serve multiple regions, get a local number for each one.
- Register for STIR/SHAKEN caller ID verification. This ensures your calls display as "Verified" on the recipient's phone, dramatically reducing the chance of being flagged as spam. OpenClaw handles the registration process for you.
- Keep your number consistent. Do not change your agent's number frequently. Consistency builds caller trust and recognition over time. If you run outbound campaigns, use the same number so contacts who call back reach your agent.
- Set up voicemail as a last resort. Configure your OpenClaw agent to handle every scenario it can before falling back to voicemail. The whole point of an AI agent is eliminating voicemail. Only use it for true edge cases.
- Test from multiple devices. After setting up your number, test calls from a landline, a mobile phone, and a VoIP line. Verify the caller ID displays correctly and audio quality is clear on each.
- Monitor call quality metrics. Check your OpenClaw dashboard for metrics like average latency, call completion rate, and audio quality scores. If you see degradation, it may indicate a carrier routing issue that support can resolve.
Troubleshooting Common Phone Number Issues
Calls Not Reaching the Agent
If calls to your number are not connecting to your OpenClaw agent:
- Verify the number is active in your ClawHub dashboard (status should show "Active")
- Check that the number is assigned to the correct agent
- If using call forwarding, confirm the forwarding is enabled on your carrier's side
- Test with a different phone to rule out caller-side issues
Caller ID Showing Wrong Number
If outbound calls display an incorrect or missing caller ID:
- Verify your outbound caller ID is configured in agent settings
- Ensure the number is registered and verified for outbound use
- STIR/SHAKEN registration can take 24-48 hours to propagate across all carriers
Number Porting Delays
If your port is taking longer than expected:
- Check for rejection notices in your ClawHub dashboard — common reasons include mismatched account information or an outstanding balance with the old carrier
- Contact your current carrier to confirm they have received and are processing the port request
- Ensure all information on the LOA exactly matches what your carrier has on file (name, address, account number)
Audio Quality Issues
If callers report poor audio, echoes, or delays:
- If using call forwarding through multiple hops (carrier → PBX → OpenClaw), try reducing the chain. Direct numbers (Option 1) or ported numbers (Option 2) eliminate intermediary hops and improve audio.
- Check your internet connection if using VoIP forwarding — jitter and packet loss degrade voice quality
- Contact OpenClaw support to check carrier routing for your specific number
What Happens After You Set Up Your Number
Once you give OpenClaw an own phone number and your agent is live, you unlock the full power of AI voice automation:
- Every call is answered instantly — no hold times, no voicemail, no missed opportunities
- Every conversation is transcribed and logged — searchable call records with full transcripts and sentiment analysis
- Actions happen in real time — appointments booked, leads scored, tickets created, dispatches triggered, all during the call
- Analytics reveal insights — understand call patterns, peak hours, common requests, and resolution rates from your dashboard
The phone number is the bridge between your business and your AI agent. Once that bridge is in place, your agent can do everything you have configured it to do — from a simple receptionist answering calls to a complex dispatch system coordinating field operations across multiple locations.
