Twilio Call Forwarding Won't Catch Your Missed Calls
Twilio call forwarding only rings another phone — miss it and the lead's gone. Here's the workflow that answers, books, and escalates, and what it costs.
You set up Twilio call forwarding so you’d stop bleeding leads to missed calls. Here’s the uncomfortable part nobody tells you when you’re wiring it up: forwarding doesn’t answer a call. It moves the ringing to a different phone and hopes someone over there is free.
If you’re under a sink, on a ladder, or asleep, that second phone rings into the same void the first one did.
Short answer: Twilio call forwarding routes an inbound call to another number — it doesn’t answer it. If the destination phone isn’t picked up, the call still dies in voicemail. To actually stop missing calls you need an answering layer on top of the forwarding: an agent (human or AI) that picks up every call, captures the caller and reason, books or escalates, and logs it to your system of record. Forwarding is the on-ramp, not the fix.
What Twilio call forwarding actually does (and what it doesn’t)
Twilio call forwarding is a routing rule, not a receptionist. It takes a call that hits your Twilio number and sends it to another destination — your cell, a teammate, a backup line, or an app. That’s genuinely useful plumbing. It is not the same as someone answering — and treating the two as equal is where owners lose money.
The cost is small and pay-as-you-go. According to Twilio’s voice pricing (2026), a US local number runs about $1.15/month, the inbound leg is roughly $0.0085/minute, and forwarding the call back out adds a second leg around $0.014/minute. A five-minute forwarded call costs you a few cents.
But “cheap routing” solves a different problem than “I keep missing calls.” Forwarding assumes a human is standing by at the other end. The entire reason you’re missing calls is that you and your team are not standing by — you’re doing the work. Forwarding a call you can’t answer to a phone you also can’t answer changes nothing except which device shows the missed-call badge.
And the cost of that miss is real. Most callers who reach voicemail won’t leave a message; they call the next name on the list. In home services, legal, and healthcare, a meaningful share of inbound calls go unanswered during busy hours and nearly all of them go unanswered after hours (Nextiva, 2026). Forwarding doesn’t move that number. An answer does.
What the call workflow should actually look like
The fix isn’t more forwarding rules — it’s putting something that answers in front of your number. Here’s the workflow I deploy, in plain terms:
- Trigger: A call hits your published number. You forward it (via Twilio or your carrier) to an answering agent instead of to a phone that might be busy.
- AI action: The agent picks up on the first ring, 24/7. It greets the caller in your business’s voice, captures name, number, and reason for calling, answers common questions, and either books the appointment or takes the details.
- System of record: The captured call writes straight into your CRM, scheduler, or a shared sheet — Jobber, Housecall Pro, Google Calendar, GlossGenius, a HubSpot record, whatever you already run. Nothing lives in the agent; the call becomes a row in the system you already trust.
- Human escalation: A true emergency or a high-value caller triggers a text or call to you with the context already attached, so you’re stepping into a qualified situation instead of a cold ring.
Forwarding still plays a role here — it’s how the call gets from your number to the agent. It’s the on-ramp. The agent is the thing that does the job. If you want the deeper build on the Twilio side specifically, I’ve mapped the Google Calendar and Twilio booking workflow end to end. This is also the core of AI lead generation for any business that gets leads by phone: you fix the inbound leak before you spend another dollar driving more calls into it.
Forwarding vs voicemail vs answering service vs an owned agent
The real choice isn’t “forward or don’t forward” — it’s what answers the call once it’s forwarded. Here’s the honest comparison, with real numbers:
| Option | What it does | What it costs |
|---|---|---|
| Twilio forwarding alone | Rings a second phone; no one guaranteed to answer | ~$1.15/mo + ~$0.02/min |
| Voicemail | Records callers who’ll mostly hang up | Free, but most leads don’t call back |
| Live answering service | A person answers, takes a message, patches calls | $135–$450/mo or $0.75–$2.00/min (Nextiva, 2026) |
| Owned AI receptionist | Answers every call 24/7, books, escalates, logs it | $8,000 once, then only your provider usage |
The wedge on the bottom row is the one a subscription can’t match: it’s a one-time deployment you own. No per-call meter, no monthly bill to me, no per-minute charge that punishes you for a busy week. A live answering service is a real option and sometimes the right one, but you rent it forever, and a 20-second hang-up still costs you a billed minute. I broke down the trade-offs between an AI receptionist, an answering service, and missed-call text-back if you want that comparison in full.
If you want to see what the misses are actually costing you before you decide, run the numbers on the missed-call cost calculator — for most service businesses the leak is bigger than any of these options.
What I’d set up first
Don’t rebuild your whole phone system. Start with after-hours and overflow, because that’s where nearly 100% of calls die. Keep your published number. Forward it to an AI Receptionist for the hours you and your team can’t pick up — nights, weekends, and the stretch when everyone’s already on a call. Let it answer, qualify, book, and text you the ones that need a human.
That narrow lane catches the calls you’re losing right now without changing how you operate during the day. Once you trust it after hours, you widen it to overflow during business hours — the second, third, and fourth simultaneous calls that currently roll to voicemail. If your busiest hours are also when you bleed the most leads, a missed-call text-back workflow layered on top means even a caller who hangs up gets an instant text instead of silence.
When Twilio call forwarding is enough (and when it isn’t yet)
Plain forwarding is fine when a human is reliably free to answer the destination. If you have a dedicated front-desk person during business hours and your call volume is low and predictable, forwarding to their line does the job, and adding an answering layer would be solving a problem you don’t have.
Hold off on the bigger build if any of these are true:
- Your call volume is genuinely low — a few calls a day you already catch.
- You don’t have a system of record yet. Fix that first; an agent that captures calls into nothing isn’t worth much. Get your CRM or scheduler in order, then automate the intake into it.
- Your calls are mostly complex, judgment-heavy conversations where a templated answer would do more harm than good. Some practices need a human on every first call, and that’s a legitimate reason to wait.
Forwarding is cheap and it has its place. It just isn’t a substitute for answering.
If you’re losing calls and forwarding hasn’t fixed it, that’s the signal.

FAQ
Does Twilio call forwarding answer my calls? +
No. Twilio call forwarding routes an inbound call to another number you choose — your cell, a partner, a backup line. It moves the ringing; it doesn't pick up. If the destination doesn't answer, the call still lands in voicemail or drops, same as before.
How much does Twilio call forwarding cost? +
Twilio bills per minute, not a flat fee. A US local number runs about $1.15/month, inbound calls are roughly $0.0085/minute, and forwarding a call out adds another per-minute leg of about $0.014/minute (Twilio, 2026). It's cheap, but it's plumbing — it doesn't include anyone answering.
What happens to a forwarded call if I don't pick up? +
It falls through to voicemail or hangs up. That's the core problem: forwarding assumes a human is free to answer the destination phone. When you're on a job, driving, or asleep, the forwarded call dies the same way the original would. Most callers who hit voicemail won't leave one — they call the next business.
Is an AI receptionist better than call forwarding? +
For catching leads, yes. Forwarding relays a call to a phone that may not be answered. An AI receptionist answers every call on the first ring, captures the caller's name, number, and reason, books or escalates, and logs it. Forwarding is a routing rule; an answering layer is the thing that actually picks up.
Can I forward calls to an AI instead of my cell? +
Yes, and that's the right use of forwarding. You keep your published number and use Twilio (or your carrier) to forward it to an AI agent that answers 24/7. The forwarding is just the on-ramp; the agent is what captures the lead, books the appointment, and texts you the ones that need a human.
