A2P 10DLCTexting

Also called 10DLC registration

The registration US carriers require before a business texts from a regular 10-digit local number. The business registers itself as a brand and describes what it will send as a campaign, and carriers review both. Texts from unregistered numbers can be filtered or blocked.

Texting registration

A2P messagingTexting

Also called application-to-person

Texts sent by a business system to people, like reminders, confirmations, and replies from a business inbox, as opposed to person-to-person texts between friends. US carriers hold A2P texts to stricter rules and require the sender to register.

Answering calls that come in when the business is closed: nights, weekends, and holidays. It can mean taking messages, booking for the next open day, or reaching someone on call for real emergencies.

After-hours call calculator

AI receptionistCalls and phone systems

Software that answers a business phone line and holds a real conversation with the caller. It understands what people say instead of asking them to press keys, answers questions from what the business tells it, takes messages, and can book appointments or transfer urgent calls to a person.

What an AI receptionist does

Answering serviceCalls and phone systems

A company whose staff answer calls for many businesses at once. Agents usually take a message and pass it on, and the service bills by the minute, by the call, or by a monthly bundle.

Answering service cost calculator

Appointment reminderFront desk and staffing

A text, email, or call sent before an appointment with the date, time, and a way to confirm or change it. A reminder gives people an easy way to cancel or move instead of just not showing up.

Appointment reminder text generator

Area codeForwarding and numbers

The first three digits of a 10-digit North American number. It points to a region, so a local area code tells callers you’re nearby, though a mobile number can move anywhere with its owner.

Area code lookup

Area code overlayForwarding and numbers

A second area code added to the same region when the first one runs out of numbers. Overlays are why many places need 10-digit dialing even for local calls.

Area code lookup

Auto attendantCalls and phone systems

Also called automated attendant, digital receptionist

A recorded greeting with a menu that sends callers to the right person or department, like “press 1 for sales.” It routes calls but can’t answer questions on its own. Most business phone systems include one.

Phone tree script generator

Call history and transcripts

Caller IDCalls and phone systems

Area code lookup

Click-to-callForwarding and numbers

Also called tel link

A link on a website or in an email that dials a number when someone taps it, written as tel: followed by the number. On a phone it saves the caller from copying digits by hand.

How many calls a phone line or service can handle at the same moment. A single person can take one call at a time, so the next caller hears a busy signal or voicemail. FrontDesk Talk answers up to 10 calls at once for each business.

Call staffing calculator

Conditional call forwardingForwarding and numbers

Also called no-answer forwarding, busy forwarding

Forwarding that only kicks in when something happens: you don’t answer, you’re already on a call, or your phone is off or out of signal. Your phone rings first, and the calls you can’t take go to the other number.

Call forwarding codes

CSRForwarding and numbers

Also called customer service record

Your current phone company’s record of your account: the name, the service address, and the numbers on it. A port goes through only when the details on your LOA match the CSR, so a mismatched name or address is a usual reason a port is rejected.

How to port your number

D

Double bookingFront desk and staffing

Two appointments in the same slot for the same person or room. It usually happens when bookings are taken in more than one place, which is why booking straight into one live calendar matters.

Connect your calendar

E

E.164Forwarding and numbers

The international standard for writing a phone number: a plus sign, the country code, then the number, with no spaces or punctuation. A US number becomes +1 followed by its 10 digits, like +15125550142. Texting and phone systems use it so every number means exactly one phone.

Phone number formatter

Erlang CFront desk and staffing

A formula call centers use to work out how many people they need on the phone. It takes the calls in an hour, how long each lasts, and your answer time target, and gives the chance a caller waits and for how long. One erlang is one person on the phone for a full hour.

FOC dateForwarding and numbers

Also called firm order commitment

The date your current phone company confirms a port will happen. On that day your number switches to the new company, usually within a few minutes, and calls start ringing there.

Overflow call answering

P

Phone scriptFront desk and staffing

Port-out PINForwarding and numbers

Also called transfer PIN, number transfer PIN

A code your current phone company gives you, or lets you create, to approve moving your number to another company. Mobile carriers usually let you make one in their app or online account. A port request without the right PIN is rejected.

PortingForwarding and numbers

The minutes your FrontDesk Talk receptionist spends on the phone. Each plan includes a set amount each month (200 on Small Talk, 450 on Real Talk, 1,000 on Big Talk), and extra Talk Time is $0.45 a minute. Calls that ring your own phone (while the receptionist is paused, or when it rings you first) don’t use Talk Time.

How Talk Time works

TCPATexting

Also called Telephone Consumer Protection Act

The US federal law that limits automated calls and texts and sets when a business needs a person’s consent to contact them. Marketing texts need stronger consent than replies to someone who contacted you first. This is general information, not legal advice.

SMS Terms

Toll-free numberForwarding and numbers

A number with a toll-free prefix like 800 or 888 that’s free for the caller and not tied to one area. Texting from one needs toll-free verification first.

Phone number formatter

Toll-free verificationTexting

The review a toll-free number must pass before it can send texts. The business describes who it is, what it sends, and how people opt in, and carriers block texts from toll-free numbers that haven’t been verified.

Texting registration

U

UCS-2Texting

The text encoding a phone switches to when a message has any character outside GSM-7, such as an emoji, a curly apostrophe, or an accented letter outside the basic set. It fits only 70 characters per segment, so the same message can cost two or three times as much to send.

SMS character counter

Unconditional call forwardingForwarding and numbers

Also called forward all calls, always forwarding

Forwarding that sends every call to the other number, so your own phone never rings. It’s the right setup when you want someone else, or an AI receptionist, to answer everything.

Voicemail greeting generator

VoIPCalls and phone systems

Also called voice over internet protocol

Warm transferCalls and phone systems

Also called attended transfer

Passing a call to someone after first telling them who is calling and why, so the caller doesn’t have to start over. The opposite is a cold or blind transfer, which puts the call straight through with no introduction.
