Human Add AI help center covers call forwarding setup for every major US carrier (Verizon, AT and T, T-Mobile, Spectrum, Comcast, RingCentral, Google Voice, OpenPhone, and twelve more), PWA install instructions for the mobile dashboard, knowledge base editing, and account management. Most setup guides take under five minutes to complete.
Comcast Business Voice (including Business VoiceEdge) supports two easy ways to forward calls: the classic *72 star code from your handset, or the web portal. This guide covers both.
The quick version
Comcast Business Voice (also branded "Business VoiceEdge" on newer accounts) supports both star codes and a web portal. Easiest: dial *72 from your Comcast Business phone, enter the 10-digit destination, hang up. Or use the portal at business.comcast.com/myaccount.
Method 1: Star code from your desk phone
1
Pick up your Comcast Business phone and listen for a dial tone.
2
Dial *72. You'll hear a new dial tone or a prompt.
3
Enter the 10-digit destination number (no 1, no spaces). Press the pound key # after the number on some phones.
4
Hang up. You'll hear two short tones that confirm forwarding is active.
5
Test by calling the Comcast Business number from another phone.
Click Voice in the left navigation, then Voice Features.
3
Pick the phone number you want to forward from the list.
4
Find "Call Forwarding Always" and toggle it on. Enter the destination number. Click Save.
5
Test - changes apply within 30 seconds.
Advanced forwarding on Business VoiceEdge
If you have the VoiceEdge product (Comcast's hosted PBX for larger deployments), the portal gives you finer-grained controls:
Selective call forwarding - only specific callers forward.
Call forwarding busy / no answer - only when the line is engaged or unanswered.
Time-of-day routing - forward everything after business hours to your AI, take calls yourself during the day.
Things worth knowing
Star codes work on Comcast Business analog lines and on most VoIP lines from the provided handset. They may not work from a softphone app - use the portal in that case.
Forwarded calls count against your Business Voice plan's minutes if you have a metered plan. Most unlimited plans don't charge extra.
If you use Polycom or Cisco desk phones provided by Comcast, the display may show "CFW" or "Forward" when forwarding is active.
Forwarding to an AI receptionist?
The whole reason you're reading this is probably to stop missing calls. If you're setting up call forwarding to send calls to a voice assistant, an answering service, or an AI, the steps above are the same - you just enter their number as the forward-to destination. Human Add AI gives you a dedicated AI receptionist that answers 24/7, captures every caller's intent, and texts you the details. Try it free for 7 days →
Troubleshooting
Star codes return a fast busy. Your plan may not include Call Forwarding Always. Sign in to the portal - if the feature isn't listed, contact Comcast Business at 1-800-391-3000.
Portal won't save changes. Try a different browser (Comcast's portal can misbehave in older Safari versions) or clear your browser cache. Make sure pop-up blockers aren't interfering.
Callers reach voicemail instead of the forward. Your "no answer" timer may be too short. In the portal, set "Call Forwarding Always" (not "No Answer") so every call routes, or increase the ring-timer.
Forwarding worked yesterday but not today. A network update can sometimes clear forwarding rules on Comcast. Redo the star code or re-save in the portal.
Every Human Add AI trial gives you a dedicated local phone number with a fully custom AI receptionist on the other end. Free for 7 days, $10 refundable activation.
Human Add AI charges $497, $997, or $1,997 per month depending on the volume tier, with outbound calling metered at fourteen cents per minute on top of the Professional and Enterprise plans. There is no setup fee, no annual contract, no per-seat charge, no per-lead charge, and no per-call charge on inbound. The platform is intentionally priced to be a flat monthly line item that an operator can compare directly against the cost of a virtual receptionist service or the salary of a part-time in-house front desk.
The Starter tier is the right entry point for most operators. It covers a single location, up to 250 inbound calls per month, and the full conversation engine. The 250-call cap maps to a typical service business doing roughly 50 to 60 inbound calls per week. Operators expecting much higher volume should price the Professional tier, which raises the cap to 750 inbound calls per month and unlocks the multi-location routing and the CRM-deep-integration matrix.
Professional at $997 monthly is also the tier where after-hours emergency escalation routing becomes standard, where the CRM integration set covers Jobber, Housecall Pro, ServiceTitan, FieldEdge, mHelpDesk, Workiz, Salesforce, HubSpot, Pipedrive, Clio Manage, Lawmatics, MyCase, PracticePanther, Dentrix Ascend, Open Dental, Eaglesoft, Curve Dental, ServiceM8, RazorSync, and twenty other vertical-specific systems, and where the SLA-backed response time on agent tuning tightens.
Enterprise at $1,997 monthly is for operators who want the volume cap removed entirely, the dedicated agent-tuning contact, the white-label phone numbers, the on-call dispatcher priority routing, and the outbound module. The outbound module unlocks four use cases at the same fourteen-cents-per-minute rate: missed-call callback (the highest-ROI use), appointment reminders (24 hours before the booked time), post-service review collection, and lead nurture for prospects who asked for information but did not book on the first call.
The questions worth asking before you switch
Can the agent handle a caller who interrupts or changes their mind mid-call?
Yes. The conversation engine is built around real conversational patterns, not menu trees. If a caller interrupts mid-sentence, the agent stops, listens, and responds to the interruption. If a caller changes their mind about the service halfway through (a common pattern when callers are still figuring out what they need), the agent rolls with the change and restarts the intake from the new point. Most generic AI receptionists fail on these two patterns, which is why the demo line at (617) 812-5251 is the recommended evaluation method.
What does the operator-facing dashboard look like on mobile?
The dashboard is a PWA (progressive web app), which means it installs on iPhone or Android home screen and runs full-screen without the browser chrome. The mobile view surfaces the call list, the booking calendar, the SMS lead alerts, the recovered-revenue math, and the agent knowledge base for in-the-field edits. Most operators run the platform from their phone after the first week of launch.
How does pricing compare to a part-time in-house receptionist?
A part-time in-house receptionist covering business hours only typically costs $2,400 to $4,200 per month all-in (hourly wage plus benefits plus equipment plus management time). Human Add AI Professional at $997 monthly covers the same hours plus the entire 5pm-to-9am gap plus weekends plus holidays. The operator gets fuller coverage at lower total cost, with the trade-off being that the answering is done by AI rather than a human. The right operator profile depends on the vertical and the brand voice expectations.
Does the AI accept payments over the phone?
Payment processing is available on the Professional and Enterprise tiers via Stripe integration. The agent collects the payment securely (PCI-compliant capture, no card numbers stored in plain text), processes the charge, and confirms the receipt by SMS. Most service operators use this for deposit collection on bookings, post-service balance collection, or estimate-acceptance fees. Standard Stripe processing fees apply on top of the monthly plan price.
What does the platform do during an internet or power outage at my office?
Nothing changes for the caller. The forwarding from your business line happens at the carrier level, which means it does not depend on your office internet or your office power. The agent runs in the cloud regardless of what is happening at your physical location. If your booking calendar is hosted on your local system (rare), the agent falls back to manual booking via SMS to your on-call dispatcher.
How does it handle robocalls and spam calls?
The platform runs a spam-detection filter on every inbound call that checks the calling number against the same spam-call databases used by major carriers. Suspected spam calls are dropped before reaching the agent, which saves both the operator's monthly call quota and the agent's processing time. Operators can adjust the aggressiveness of the spam filter from the dashboard or whitelist specific numbers that the filter mistakenly flags.
Is there an API for custom integrations?
Yes. The Human Add AI REST API covers webhook delivery for every call event (call-received, call-answered, call-completed, booking-created, lead-flagged, sentiment-detected), CRUD access to the knowledge base and intake script, calendar push for booking events, and a read-only endpoint for call recordings and transcripts. The full API documentation is available at /api-docs and access is enabled by request on the Professional and Enterprise tiers.
How do I evaluate it without committing?
The best evaluation is the public demo line at (617) 812-5251. Call from any phone and run a real scenario through the production agent. After the demo, the next step is the ten-minute onboarding form, which builds a custom test agent for the specific business. The test agent is free to run and use, and only converts to a paid plan once the operator decides to forward their real business line. The whole evaluation path takes about two business days end-to-end with no commitment.
What changes after the first month on the platform
After thirty days on Human Add AI, three things have changed for the typical operator. First, the recovered-revenue math has compounded into a concrete dollar number that the operator can see in the dashboard and in the bank account. For most single-location service businesses, the first-month recovered revenue lands between $6,000 and $25,000, against a $497 to $997 plan cost. The platform has paid for itself many times over, and the operator mental model has shifted from "evaluating a new vendor" to "operating a critical revenue tool".
Second, the agent has been tuned to the specific cadence of the business. Tuning continues forever (every business evolves, every season brings new call patterns, every new service line needs new intake questions), but the bulk of the agent customization is done in the first 30 days. After that, the operator can edit the knowledge base from the dashboard for most changes and only needs to ping the Human Add AI team for the larger script revisions.
Third, the operator has started thinking about the second-order use cases the platform unlocks. Outbound missed-call callback usually goes live in month two for operators on Professional or Enterprise. Appointment reminder calls usually go live in month three. By month four, the platform is doing both inbound and outbound work that previously required either a part-time staffer or a separate scheduling service, and the operator is running a tighter business with the same overhead.
The under-discussed second-order benefits
Most operators sign up for Human Add AI to fix one specific problem (missed calls, voicemail leakage, expensive virtual receptionist bills) and then discover a few second-order benefits that did not show up in the original ROI calculation. The biggest is the reduction in cognitive load: the phone stops being a tax on the operator attention, which frees mental bandwidth for the harder work of running a service business.
The second is the data infrastructure. Every call is recorded, transcribed, sentiment-scored, and tagged with the intake answers. After six months of operation, the operator has a searchable database of every customer interaction, which becomes useful in unexpected ways: identifying the most common objections, spotting the price-shopping patterns by neighborhood, tracking how the seasonal call mix shifts, and proving claims in any dispute.
The third is the team-onboarding lift. New employees joining the business can listen to hundreds of real customer calls during their first week, which is the fastest way to absorb how the business actually talks to customers. The dashboard has filters for service type, time of day, and outcome, so new staff can sample the conversations that map to their role.
