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.
Spectrum offers two very different services - Mobile (wireless) and Business Voice (VoIP landline). Each uses a different method to set up call forwarding. This guide covers both.
The quick version
If you have Spectrum Mobile, use the Verizon codes (it runs on Verizon's network): dial *72 then the 10-digit number to enable, *73 to disable. If you have Spectrum Business Voice (landline/VoIP from your Spectrum cable bundle), use the My Spectrum Business portal or dial *72 from the business phone.
Spectrum Mobile: star-code method
1
Open the dialer on your Spectrum Mobile phone. Spectrum Mobile runs on the Verizon network, so the same star codes work.
2
Dial *72 followed by the 10-digit destination number with no spaces. Example: *725551234567.
3
Press call. Listen for the short confirmation tone, then the call ends.
4
Test with another phone. Call your Spectrum Mobile number - it should ring at the forwarding destination.
Go to Services → Voice. Find the number you want to forward.
3
Click Manage Features → Call Forwarding. You'll see options for Always, Busy, No Answer, and Selective forwarding.
4
Toggle Call Forwarding Always on and enter the 10-digit destination number. Save.
5
Test by calling the Spectrum Business number from another line.
Star-code alternative for Business Voice
From the Spectrum Business desk phone, dial *72, wait for the dial tone, enter the 10-digit destination, hang up. To disable, dial *73. Some Spectrum Business deployments use *90 for busy-forwarding and *92 for no-answer-forwarding.
Things worth knowing
Spectrum Business Voice is hosted VoIP - changes in the portal apply immediately without restarting the phone.
Spectrum Business lets you set different rules by time of day (e.g., forward after 5pm) under Selective Call Forwarding. Useful if you only want the AI to cover after-hours.
Spectrum Mobile doesn't have a separate forwarding UI in its app - you have to use the star codes.
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 don't work on Spectrum Business. Some Business Voice plans have star codes disabled in favor of the web portal. If *72 fails, log in at spectrumbusiness.net/myspectrum.
You don't see Call Forwarding in the portal. You may not have the right permissions. Only the primary account holder or a designated admin can change call routing. Call Spectrum Business support at 1-866-314-7195.
Forwarding activated but calls still ring your old number. Spectrum Mobile forwarding applies per-line. Make sure you set it from the specific line being forwarded, not another line on the same family plan.
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.
The Human Add AI pricing page lists three tiers, and the differences between them come down to three axes: how many inbound calls per month, how many physical or logical locations are routed by the same agent, and whether outbound calling is enabled. Starter at $497 monthly handles up to 250 inbound calls, a single location, and inbound only. That works for the smallest single-truck operations, solo professionals, and any operator who wants to pilot the platform before scaling.
Professional at $997 monthly is where most service-business operators end up. The 750-call ceiling is generous for any single-location business with normal inbound volume, the multi-location routing lets a business with two or three offices share a single agent with location-aware booking, and the deeper CRM integration matrix removes the manual hand-off step between the receptionist and the field-service software. Professional is also the tier where the SLA tightens on the response-time guarantees and on the build-tuning cadence after launch.
Enterprise at $1,997 monthly is for high-volume operators who want unlimited calls without watching a meter, white-label phone numbers, a named tuning contact at Human Add AI, and the outbound module. Outbound calls billed at fourteen cents per minute give the platform missed-call callback, appointment reminder, lead-nurture, and review-collection use cases. The outbound meter is visible in the dashboard with a hard-cap option for any operator who wants to bound monthly spend.
Across all three tiers, the conversation quality, the booking automation, the CRM sync, the SMS lead alerts, the call recording with searchable transcripts, the dashboard, and the support team are identical. The platform is engineered so a Starter customer should never feel like they are using a worse product, only a smaller-volume version of the same product.
Questions operators ask before signing up
How is the call quality measured?
Three quality signals get tracked on every call. The first is conversation completion: did the agent successfully complete the intake or did it transfer to a human. The second is booking conversion: of completed calls, what percentage resulted in a booked appointment. The third is post-call sentiment: a brief categorization (positive, neutral, negative) based on the caller's word choice during the conversation. All three roll into the weekly summary, with per-call detail in the dashboard.
What happens when a caller asks for a price?
The agent quotes the prices the operator entered during onboarding (flat rates, hourly rates, service-specific ranges). For services where pricing depends on a site visit or a custom scope, the agent says so explicitly and offers to book the free estimate. The platform never invents a price the operator did not provide, which protects both the operator from underquoting and the customer from over-promising.
Does the agent handle Spanish or other languages?
The agent handles Spanish natively at no extra cost. The caller can switch language at any point in the conversation; the agent picks up the language change automatically. Other languages (Vietnamese, Mandarin, Portuguese, French, Korean, Arabic) are available on the Professional and Enterprise tiers with onboarding-time setup. The booking confirmation SMS and the lead alert SMS go out in the caller's preferred language.
What if my call volume spikes?
The platform handles concurrency without queuing. Every inbound call gets its own agent instance, so 25 callers dialing simultaneously each get answered in two rings without any of them hearing hold music or a busy signal. The pricing tier governs monthly call volume, not concurrent-call capacity. If a tier's monthly cap is exceeded, the platform keeps answering calls and the dashboard surfaces an upgrade recommendation; calls are never dropped at the tier boundary.
How is missed-call callback different from outbound calling?
Missed-call callback is a specific outbound use case where the agent calls back any caller who hung up before reaching the agent (usually within 90 seconds). It is enabled by default on Professional and Enterprise. General outbound calling is broader (appointment reminders, lead nurture, review collection, post-service follow-up) and is billed at fourteen cents per outbound minute on a transparent meter. The missed-call callback uses outbound minutes but operators rarely cap it because the ROI on a missed-call callback is the highest of any outbound use case.
Do I have to switch my existing phone number?
No. The forwarding model preserves the existing business number entirely. The caller dials the same number they always dialed; the carrier silently forwards the call to the Human Add AI number behind the scenes; the agent answers. The caller-facing number, the existing phone listings, the Google Business Profile, and any print marketing all stay exactly the same.
How does it handle existing customer calls vs. new lead calls?
The agent recognizes existing customers via the inbound number lookup against the CRM. When a known customer calls, the agent greets them by name (using the CRM record) and routes the conversation to the appropriate path (existing-customer support questions, follow-up scheduling, billing questions). New leads get the full intake script. The split is configured during onboarding and adjustable from the dashboard.
What does the support team look like?
A real human at Human Add AI responds within four business hours on Starter, within two business hours on Professional, and inside one business hour on Enterprise. Support covers script edits, integration questions, billing questions, and any urgent issue with the live agent. The support contact is the same human who built the agent during onboarding, which means no ticket-handoff between front-line support and engineering.
What launch week looks like in practice
Launch week (the first seven days after the agent goes live on the forwarded line) follows a predictable pattern that the Human Add AI team has now run hundreds of times. Day one and day two are the noisy days: the agent is handling every inbound call, the operator is double-checking the SMS alerts and the calendar bookings, and a few edge cases come up that need quick tuning. The Human Add AI team is monitoring a random sample of calls and pushing live adjustments to the agent script for any awkward patterns.
By day three and day four, the noise drops sharply. The agent is handling the common call patterns smoothly, the bookings are landing on the calendar without manual intervention, and the operator is starting to ignore the SMS alerts because they trust the system. The first emergency-routing scenario usually hits in this window, and the operator sees the on-call dispatcher get the high-priority SMS within seconds of the agent recognizing the emergency signal in the caller voice.
By day five, six, and seven, the system is fully baseline. The operator stops thinking about the phone at all. The weekly summary email on day seven shows the first concrete recovered-revenue number: the count of bookings that came from calls outside business hours, the dollar value attached to those bookings using the average ticket size from onboarding, and the comparison against the historical voicemail pattern. For most operators that number lands somewhere between $2,000 and $8,000 in recovered revenue for the first week alone.
The honest evaluation timeline
The honest evaluation timeline for an operator deciding whether to install Human Add AI looks something like this. Day zero: call the demo line at (617) 812-5251 from any phone and run a real scenario. The demo takes about ninety seconds and gives a faithful preview of conversation quality. If the conversation quality passes the bar, proceed. If it does not, the operator has saved themselves the rest of the evaluation. Day one: fill out the ten-minute onboarding form. This creates a custom test agent for the specific business, which is free to use during evaluation.
Day two: the Human Add AI team builds the test agent and ships back recorded test calls. The operator listens to the samples, requests any adjustments, and decides whether to proceed. Day three: the operator forwards a test line (a Google Voice number, a secondary business line, or a fresh Twilio number) to the agent and runs a week of real test calls. Day ten: review the test-week data in the dashboard, compare recovered-revenue against the plan price, and decide whether to forward the real business line.
For operators who already know they have a missed-call problem, the evaluation usually collapses into a much shorter window: call the demo, fill the onboarding form, hear the recorded samples, forward the business line. Most operators who go this path are live and recovering missed-call revenue inside 72 hours of first hearing the demo.
