A2P call

別名: Application-to-person call

An A2P (application-to-person) call is a voice call started by software rather than by a person dialling. In India, TRAI’s 2026 amendment defines A2P calls as calls initiated by an application, software system or automated platform without direct human dialling, including autodialled, robo and prerecorded calls.

重要な理由: In India, every business that makes A2P calls must declare them to its telecom operator in advance, with the numbers it will use; undeclared A2P calls are treated as unsolicited commercial communication.

LumaKolでは: Every LumaKol call is placed from the agent’s own phone. The optional auto-dial next lead feature and Power Dialer start the next call after a countdown, so owners can switch auto-dial off for the whole workspace, which turns Power Dialer off too.

AHT (average handle time)

別名: Average handling time

Average handle time is the average length of a call from start to finish, usually including any time spent on hold and on notes or follow-up work right after the call.

重要な理由: Very short calls can mean callers rush or hang up early; very long ones can mean they lack a clear next step. Look at AHT next to outcomes, never on its own.

Auto dialer

別名: Autodialer, Automatic dialer

An auto dialer is software that dials phone numbers for the caller, so nobody types or taps each number. Power and predictive dialers are two common types.

重要な理由: Auto dialers save time between calls, but many calling rules treat automatically dialled calls differently from hand-dialled ones, so check what applies where you call.

LumaKolでは: LumaKol offers auto-dial next lead: after an outcome is logged, the next lead in the agent’s queue is dialled from their own SIM after a short countdown they can cancel, one call at a time. Power Dialer does the same for a whole list as one session.

Call outcome

別名: Call result

A call outcome is what happened on a call, recorded right after it: for example connected and interested, call back later, not reachable, wrong number, or asked not to be called.

重要な理由: Outcomes turn a call log into something you can act on. They decide the next follow-up, feed the reports, and show which leads are worth another try.

LumaKolでは: The LumaKol app asks for the outcome when a call ends; each outcome can move the lead to a stage, book the next follow-up and ask a few questions.

Callback

別名: Call back

A callback is a call you promised to make at a time the lead chose, such as “call me after 6” or “call me next Tuesday”.

重要な理由: A missed callback tells the lead how the rest of the deal will go. Callbacks need a reminder at the right time and a place at the top of the caller’s list.

LumaKolでは: Booking a follow-up from the outcome screen sets a reminder on the caller’s phone, and overdue callbacks move up the calling queue.

Caller ID

別名: CLI, Calling line identification

Caller ID is the number (and sometimes a name) shown to the person you are calling. Telecom operators call the number itself the CLI, for calling line identification.

重要な理由: People decide whether to answer from the caller ID. A number they recognise, or one that matches the business they enquired with, gets answered more often.

LumaKolでは: LumaKol calls show the agent’s own mobile number, because they are ordinary calls from the agent’s SIM.

Click-to-call

Click-to-call starts a phone call when you click a number or a Call button on a screen, instead of dialling by hand.

重要な理由: It removes typing mistakes and saves a few seconds on every call, which adds up over a day of calling.

LumaKolでは: In LumaKol, clicking Call on a lead in the web app rings out from the caller’s own phone.

Cloud telephony

Cloud telephony is a phone system run by a provider over the internet: virtual numbers, call routing, IVR menus and recording, usually paid per minute or per channel.

重要な理由: It suits high-volume inbound lines and contact centres. Outbound calls come from the provider’s numbers rather than your team’s own mobile numbers.

Cold calling

別名: Cold call

Cold calling is calling people or businesses who have not asked to hear from you, usually from a bought or researched list.

重要な理由: Cold calls are the most regulated kind of sales call: do-not-call registers, number series and consent rules apply in most markets. Check them before you start.

続きを読む: Cold calling CRM

Connect rate

Connect rate is the share of dialled calls that are answered by someone. Ten answered calls out of fifty dials is a 20% connect rate.

重要な理由: It shows how reachable your list is and whether timing, caller ID or spam labels are hurting you, before you judge what callers say once connected.

LumaKolでは: In LumaKol a call counts as connected when the phone recorded it as answered and the outcome saved for it does not say otherwise. An answering machine that picked up for a few seconds, saved as No answer, counts as not answered.

Contact rate

Contact rate is the share of leads (not dials) your team managed to speak to, usually the right person rather than anyone who picked up.

重要な理由: A team can make plenty of dials and still reach few people. Contact rate tells you how much of your list has actually heard from you.

Conversion rate

Conversion rate is the share of leads that reach a chosen result, such as a booked visit, a demo or a sale, out of all leads in a period or from a source.

重要な理由: Comparing conversion by lead source and by caller shows where to spend money and who needs coaching.

CRM

別名: Customer relationship management

A CRM (customer relationship management system) is software that keeps every lead and customer in one place, with their details, history and the next thing to do.

重要な理由: Without one, leads live in spreadsheets, WhatsApp chats and memory, and follow-ups depend on who remembers. A calling CRM adds the calls themselves to that record.

続きを読む: Telecalling CRM

Disposition

別名: Call disposition, Disposition code

A disposition is a label a caller picks after a call to say how it ended, such as interested, call back, not reachable or not interested. It is another name for the call outcome.

重要な理由: A short, clear list of dispositions keeps reports honest. Too many options and callers pick whatever is first.

LumaKolでは: LumaKol calls these outcomes; admins set the list and what each one does.

DLT

別名: Distributed Ledger Technology platform

DLT is the Distributed Ledger Technology platform that India’s telecom operators run under TRAI’s rules. Businesses that send commercial calls or SMS register on it as senders, together with their SMS headers and message templates.

重要な理由: In India, commercial SMS need a registered header, and customers’ DND preferences are applied through the DLT system. Calls and messages that bypass it are the main target of enforcement.

LumaKolでは: LumaKol does not register senders, headers or templates on DLT. Messages open in the agent’s own WhatsApp or SMS app for the agent to send.

DND

別名: Do Not Disturb

DND (Do Not Disturb) is India’s system that lets a mobile user block all commercial calls and messages, or chosen categories of them. The preference is stored in the National Customer Preference Register and can be set through the TRAI DND app, the operator’s app or website, or by calling or texting 1909.

重要な理由: Calling teams in India should screen bought or cold lists against DND before calling. A person who registered can complain about unwanted commercial calls within 7 days.

LumaKolでは: LumaKol does not check numbers against the DND register.

Do not call (DND) list

別名: Internal do-not-call list, Company do-not-call list, DNC list

A do-not-call list is a business’s own record of people who asked it not to call them again. It is separate from national registries such as India’s DND, the US National Do Not Call Registry or the UK’s TPS, which people join to refuse sales calls in general.

重要な理由: Many calling rules expect a business to honour a request not to be called whether or not the number is on a national registry. One repeat call after a clear refusal is the call people complain about.

LumaKolでは: In the LumaKol web app a lead can be marked Do not call, with a reason. The web app and the browser extension then refuse to call it, and only owners, admins and team leads can remove the mark.

Do Not Call Registry (US)

別名: National Do Not Call Registry, DNC

The National Do Not Call Registry is the US list of landline and mobile numbers whose owners do not want telemarketing calls. Registration is free at donotcall.gov.

重要な理由: Telemarketers selling in the US must not call registered numbers unless an exemption applies, and must honour do-not-call requests made during a call. Several states keep their own lists too.

公式の情報源: FCC: Stop unwanted robocalls and texts続きを読む: US calling rules

DPDP Act

別名: Digital Personal Data Protection Act, 2023

The Digital Personal Data Protection Act, 2023 is India’s law on digital personal data. It calls the person the data is about the Data Principal and the business that decides why and how the data is processed the Data Fiduciary, and it requires consent that is free, specific, informed, unconditional and unambiguous, with a clear affirmative action.

重要な理由: A calling team’s lead list is personal data. The Act’s rules were notified in November 2025 and apply in phases, with penalties that can reach ₹250 crore for failing to protect data.

LumaKolでは: For its leads’ data, your business is the Data Fiduciary and LumaKol processes it for you under the Data Processing Addendum.

Drip sequence

別名: Drip campaign, Cadence

A drip sequence is a planned series of touches sent to a lead over days or weeks, such as an email on day one, a WhatsApp on day two and a call on day three, which stops when the lead responds.

重要な理由: Most leads need several touches before they reply. A sequence makes sure the next one happens even on a busy day.

LumaKolでは: LumaKol sequences send emails from your own connected mailbox, prompt WhatsApp and SMS from the owner’s phone, create call tasks, and end when a call is answered or the lead is won or lost.

First call resolution

別名: FCR

First call resolution is the share of calls where the customer’s question or problem is settled on the first call, with no follow-up needed.

重要な理由: It is mainly a support measure. In sales, the closer equivalent is how often the first call ends with a clear next step booked.

Follow-up

A follow-up is the next planned contact with a lead after a call or message, with a date and time attached.

重要な理由: Most sales are lost to follow-ups that never happened, not to a bad first call. Every call should end with the next one booked.

LumaKolでは: Choosing an outcome in LumaKol books the follow-up, reminds the caller on their phone and puts the lead back in the queue when it is due.

続きを読む: Follow-ups and reminders

IVR

別名: Interactive voice response

IVR (interactive voice response) is the automated menu callers hear on a business line, such as “press 1 for sales”, which routes the call or answers simple questions.

重要な理由: It helps inbound lines with many callers. For outbound sales from mobile numbers there is no IVR: the lead hears the caller straight away.

Lead

A lead is a person or business who might buy from you, usually with a name, a phone number and where they came from.

重要な理由: A calling team’s whole day is organised around leads: who to call next, what they asked for and when to call again.

Lead scoring

Lead scoring gives each lead a number that estimates how likely it is to buy, based on things like how new it is, where it came from and how earlier calls went.

重要な理由: It tells callers which leads to call first when there are more leads than hours in the day.

LumaKolでは: LumaKol scores leads and orders each caller’s queue by score, so a new enquiry that has never been called scores higher.

続きを読む: Call the best leads first

Lead source

A lead source is where a lead came from: a website form, an ad, a portal such as IndiaMART or JustDial, a walk-in, a referral or an imported list.

重要な理由: Sources convert very differently. Tracking them shows where your best customers come from and which channels are wasting money.

LumaKolでは: Every LumaKol lead keeps its source, and a call script can be set for a lead source.

続きを読む: Lead sources compared

NCPR

別名: National Customer Preference Register

The NCPR (National Customer Preference Register) is the register behind India’s DND system. It stores each mobile user’s choice to block all commercial communication or only chosen categories of it.

重要な理由: Commercial calls and messages that ignore a registered preference can lead to complaints and action against the sender’s numbers.

公式の情報源: TRAI: TCCCPR 2018 (regulation text)続きを読む: India calling rules

Opt-out

別名: Do-not-call request

An opt-out is a person’s request to stop being contacted, for example by saying “please don’t call me again” on a call or using an unsubscribe link.

重要な理由: An opt-out should reach everyone on the team at once. In many markets ignoring one is a breach of the rules, and it always costs goodwill.

LumaKolでは: Logging the outcome “Requested no contact” in LumaKol takes the lead out of every queue and marks it Do not call, and with the do-not-call setting on, the apps refuse to dial it. A lead can also be marked Do not call by hand on the web, with a reason.

PECR

別名: Privacy and Electronic Communications Regulations

PECR (the Privacy and Electronic Communications Regulations) are the UK rules on marketing calls, texts and emails, enforced by the ICO. They sit alongside the UK GDPR.

重要な理由: PECR is where the UK rules on TPS screening, caller ID and automated calls come from.

公式の情報源: ICO: Telephone marketing guidance続きを読む: UK calling rules

Pipeline

別名: Sales pipeline

A pipeline is the set of stages a lead moves through from first contact to a sale, such as new, contacted, visit booked, negotiating and won.

重要な理由: It shows at a glance how many deals are at each step and where they get stuck.

Power dialer

A power dialer calls the next number on a list automatically as soon as the caller finishes the previous call, one call at a time.

重要な理由: It cuts dead time between calls without the dropped calls a predictive dialer can cause.

LumaKolでは: LumaKol’s auto-dial next lead works in a similar way, from the agent’s own SIM, after a countdown the agent can cancel. Power Dialer runs it as one session over a whole list.

Power dialing session

別名: Calling session, Power dialer session

A power dialing session is a block of time in which a caller works through a list back to back, with the next number dialled automatically after each call. It is how a power dialer is usually run.

重要な理由: Measuring sessions shows how much time callers really spend calling and how many calls they make per active hour, which a daily call count hides.

LumaKolでは: LumaKol’s Power Dialer runs these sessions on Android: after each hang-up the app counts down a 3 to 60 second gap and dials the next lead from the agent’s own SIM, tags calls that don’t connect for you, and Pause, Skip lead and End session work at any time. Managers see each agent’s sessions in Reports → Calling sessions.

続きを読む: Power Dialer in LumaKol

Predictive dialer

A predictive dialer dials several numbers at once and connects answered calls to whichever agent is free, using statistics to guess when agents will be available.

重要な理由: It raises talk time for large call centres, but answered calls with no free agent get dropped or delayed, which many regulators restrict. LumaKol is not a predictive dialer.

Round robin

Round robin assigns new leads to callers in turn: the first to one person, the next to the next person, and so on.

重要な理由: It spreads leads fairly and stops new enquiries waiting for someone to claim them.

LumaKolでは: LumaKol can assign imported leads and leads from connected sources round robin across chosen callers.

SIM-based calling

SIM-based calling means sales calls go out over the mobile network from the SIM in the caller’s own phone, rather than over the internet through a virtual number.

重要な理由: Leads see a normal mobile number, there is no per-minute platform charge, and calls work wherever the phone has signal.

LumaKolでは: LumaKol is built on it: callers ring leads from their own SIM, and the Android app logs each work call to the right lead.

続きを読む: Keep your number

Spam label

別名: Spam likely, Suspected spam

A spam label is a warning such as “Spam likely” shown on an incoming call by the phone, the operator or a caller ID app, based on reports and calling patterns.

重要な理由: A labelled number gets far fewer answers. High volumes of short calls and complaints are common causes. In India, TRAI’s 2026 amendment says the 140, 1600 and 1601 series must not be flagged as suspected spam.

Speed to lead

別名: Lead response time

Speed to lead is the time between a lead arriving and your first call to them.

重要な理由: An enquiry is warmest in the first minutes. The longer the wait, the more likely the lead has moved on or called someone else.

LumaKolでは: LumaKol’s coaching report measures speed to lead, and new leads that have never been called score higher in the queue.

Stage

別名: Pipeline stage

A stage is one step in a pipeline, such as contacted, visit booked or negotiating. Each lead is in exactly one stage at a time.

重要な理由: Stages tell a caller what the next call is for, and tell a manager where deals stall.

LumaKolでは: In LumaKol a call script can be set per stage, so the caller sees the one for where the lead is now.

Talk time

Talk time is the total time a caller spends in connected conversations, usually measured per day or per week.

重要な理由: It is a better measure of effort than the number of dials, but read it next to outcomes: long talk time with no next steps booked is a coaching topic.

LumaKolでは: LumaKol adds up connected calls only, so the seconds an answering machine took before the caller saved No answer are not talk time. Agents also see their own talk time beside their active time on My performance.

TCCCPR

別名: Telecom Commercial Communications Customer Preference Regulations, 2018

The TCCCPR (Telecom Commercial Communications Customer Preference Regulations, 2018) are TRAI’s rules on commercial calls and messages in India. They cover DND preferences, sender registration on DLT, consent, complaints and action against unregistered senders.

重要な理由: They were amended in February 2025 and again in September 2026. Under the 2026 amendment, calls based on a customer’s own written or digital enquiry are allowed for seven days from that enquiry.

TCPA

別名: Telephone Consumer Protection Act

The TCPA (Telephone Consumer Protection Act of 1991) is the US federal law on telemarketing calls and texts, with rules set by the FCC. It restricts autodialled and prerecorded calls and texts, limits telemarketing calls to homes to between 8 a.m. and 9 p.m., and is the basis for the FCC’s do-not-call rules.

重要な理由: Autodialled or prerecorded calls and texts to mobiles generally need prior consent, and commercial texts need written consent. People can sue for each unlawful call, so mistakes repeated across a list add up.

公式の情報源: FCC: Stop unwanted robocalls and texts続きを読む: US calling rules

Telecaller

別名: Telesales agent, Inside sales caller

A telecaller is a person whose job is to call leads and customers by phone: answering enquiries, qualifying them, booking the next step and following up.

重要な理由: Telecallers usually make dozens of calls a day, so tools that cut typing and remembering give them more time on the phone.

TPS and CTPS

別名: Telephone Preference Service, Corporate Telephone Preference Service

The TPS (Telephone Preference Service) is the UK register of individuals who have opted out of live marketing calls; the CTPS is the same for companies and other corporate bodies.

重要な理由: Under PECR you must not make unsolicited live marketing calls to a registered number unless that person has specifically consented to your calls. Automated marketing calls need specific consent whether or not the number is registered.

公式の情報源: ICO: Telephone marketing guidance続きを読む: UK calling rules

VoIP

別名: Voice over IP, Voice over Internet Protocol

VoIP (voice over internet protocol) carries phone calls over an internet connection instead of the mobile network, usually from an app or a browser using a virtual number.

重要な理由: VoIP is flexible and good for shared inbound lines, but call quality depends on the internet connection, and leads see a number they may not recognise.

続きを読む: Your own number or VoIP?

Warm lead

A warm lead is someone who has already shown interest, for example by filling in a form, sending an enquiry or asking for a callback. A cold lead has not.

重要な理由: Warm leads convert far better and are the calls people expect, so they should be called first and fast.

140 series numbers

別名: 140xx numbers

140 series numbers are the Indian phone numbers set aside for promotional calls. TRAI requires promotional calls to come from 140-series numbers through registered telemarketers.

重要な理由: Most unwanted commercial calls in India come from ordinary 10-digit numbers that bypass the system, and complaints against such numbers can get them disconnected. Promotional campaigns belong on the 140 series, not on agents’ mobile numbers.

1600 series numbers

別名: 160 series, 1600xx numbers

1600 series numbers are the Indian phone numbers TRAI has set aside for service and transactional calls from the financial sector, such as banks and insurers, so people can tell those calls apart from other commercial calls.

重要な理由: If you sell or service financial products for a regulated entity in India, its service and transactional calls are moving to these numbers.
