Cloud telephony means your business phone service runs over the internet instead of on a landline or a box in your office. For a small business owner, that changes three things: how you get a business number, where calls can ring, and what you can see afterwards. This guide explains the parts in plain words, what you actually need, and the mistakes to avoid before you pay for anything.
What is cloud telephony, and how is it different from a landline or a PBX?
A landline is a copper line into your shop or clinic. A PBX or EPABX is a hardware box that shares a few lines across several desk phones. Cloud telephony moves that "box" to your provider's servers, so you manage numbers, menus and call routing from a web page or an app, and calls travel over the internet and the normal phone network.
| Landline | PBX or EPABX | Cloud telephony | |
|---|---|---|---|
| Where it lives | A line into one building | A box in your office | Provider's servers, managed from a dashboard |
| Where calls can ring | The desk phone | Desk phones on that box | Mobiles, desk phones, apps, more than one at a time |
| Setup | Line installation | Hardware and wiring | Mostly online, no wiring |
| Changing the setup | Call the line provider | Call the technician | Edit a setting yourself |
| Call history and recordings | Usually none | Depends on the box | Usually a call log, recording on many plans |
The "usually" matters. Features differ a lot between providers, so treat any list, including this one, as a set of questions to ask rather than a promise.
What can cloud telephony do for a small business?
You will see the same few building blocks on almost every provider's page. Knowing what each one is makes a quote easy to read.
- Virtual number: a business number that is not tied to one SIM or one phone. Calls to it are sent wherever you choose.
- Call forwarding and routing: ring one phone, then another if nobody picks up, or send calls to a different person by time of day.
- IVR (the "press 1" menu): a recorded menu that lets callers choose a department or language before a person answers.
- Call recording and call log: a record of who called, when, how long they waited and whether anyone answered.
- Missed call handling: a list or alert of calls nobody picked up, so someone can call back.
- Extra users: separate logins for you and your staff.
None of these books an appointment or answers a question on its own. They decide where the call goes. A person, or something that can talk, still has to pick it up.
Do you actually need it, or is your mobile number enough?
If you are a one-person business with one phone that you always carry and answer, a mobile number can be enough. Cloud telephony starts to help when one of these is true:
- Your number is printed everywhere and it is also your personal phone.
- Two or more people should be able to answer the same business number.
- Calls go unanswered when you are with a client, in a class or on a job.
- You want to know how many calls came in and how many were missed.
- You want a business number that does not change when a staff member leaves with their SIM.
If none of these apply, you can wait. Paying for a menu and a dashboard you do not use is an easy way to overspend on phones.
What do the official rules say about cloud telephony?
This section is general information from official pages, not legal advice. Two official sources are worth knowing about, and both are narrower than they first sound.
Department of Telecommunications (DoT) and OSP rules. In November 2020 the Ministry of Communications announced simplified guidelines for Other Service Providers (OSPs). Its official press release says the registration requirement for OSPs "has been done away with altogether". That release is about BPO and IT-enabled service companies, so it is not a licence guide for a clinic or a salon. If your provider says a particular rule applies to you, ask which one, and read the current guidelines on dot.gov.in.
TRAI and outbound calls. In February 2025 TRAI announced amendments to its commercial communication regulations. The TRAI press release says normal 10-digit numbers should not be used for telemarketing, the 140 series continues for promotional calls, and a 1600 series is designated for transactional and service calls. If you plan to call customers, for reminders or for promotions, ask your provider which number series and consent process it uses for that kind of call.
In short:
- DoT: the 2020 release is about BPO and IT-enabled services, not a clinic or salon licence.
- TRAI: promotional calls use the 140 series and service calls the 1600 series.
- Ask your provider which rules and number series apply to your calls.
- Recording consent is not covered by a cited rule here.
This guide does not cite a rule on call recording consent, because none was verified from an official page. A sensible habit is to tell callers that a call may be recorded, and to ask your provider and your adviser what applies to you.
How do you choose a cloud telephony provider?
Treat this as a checklist and tick what you really need. Most small appointment businesses need the first six items.
- Keep your existing number or get a new one? Ask if you can port your current number, or whether the provider issues a new virtual number that you will have to print everywhere.
- Mobile app or softphone for your team. Staff should be able to answer on the phones they already own.
- Forwarding rules. Can you set working hours, a backup number and a holiday message?
- Missed call list. Does a missed call create a record someone must act on?
- Recording and storage. Is it included, and how long is it kept?
- Reports you will read. Calls answered, missed, and average wait. Ignore the other dashboards.
- Language options for menus, if your callers use Tamil, Hindi or English.
- Support in your time zone and language, reachable when the line fails.
- Exit. Can you cancel monthly, and do you keep your number if you leave?
On cost, vendors usually charge for some mix of: the number itself, the number of users, calling minutes, recording storage, and setup. Quotes that look cheap per month can grow once minutes, extra users and add-ons are counted, so ask for the full monthly cost for your expected call volume, in writing.
How should you set up your call flow?
A simple flow beats a clever one. Most clinics, tutors and repair businesses do well with this order:
- Decide who should get the call first, and in which hours.
- Choose a second person or phone if the first does not answer.
- Decide what happens when nobody answers: a missed call list, a callback, or an answering service.
- Record a short greeting with your business name and hours.
- Add an IVR menu only if you really have separate departments. Two options are plenty.
- Write down who clears the missed call list each morning.
Callers who have to press through three menus to reach a person may simply hang up. A good test is to call your own number from a phone that is not yours, then imagine you have never heard of the business.
How do you test a provider before you commit?
Use any trial or first month as a test, not a formality. Over one week:
- Call from a mobile, a landline and a number outside your city.
- Call during your busiest hour and after closing time.
- Ask a friend to call twice at once, to see what the second caller hears.
- Check that missed calls appear in the log with the right time.
- Listen to one recording for sound quality, in a noisy room as well as a quiet one.
- Ask support a question and note how long the reply takes.
- Count how many missed calls were actually returned, and how fast.
If the product passes, you can scale. If it fails at step 3 or step 7, the problem will be there in busy season too.
What mistakes should you avoid?
- Buying features before you know your problem. If your problem is missed calls, an outbound dialer is the wrong tool.
- Publishing a new number without keeping the old one working. Customers who saved your old number will think you closed.
- Long IVR menus. Every extra option can lose a caller.
- No owner for the missed call list. A list nobody reads is just a record of lost customers.
- Forgetting internet. Calls on apps need a stable connection at the place where staff answer. Keep a backup number that rings a normal phone.
- Ignoring the cost of unanswered calls. For example, if you miss 12 booking calls a month and a visit is worth Rs 1,000, then even if only 4 of those callers would have booked, that is Rs 4,000 of work walking away. This is a labelled example, so use your own numbers.
Who answers the call after the menu?
Cloud telephony decides where a call goes. It does not decide who is free to talk. A clinic owner with a patient in the chair, a tutor in a class, or a plumber on a ladder cannot take the call, whatever the routing says. That is where the call ends up in a missed list, which someone must clear later.
You have a few options, and the right one depends on your call volume, your hours and how much a missed booking costs you:
- A receptionist: the most personal, but the least flexible for evenings and Sundays.
- An answering service: a person takes a message for you.
- An AI receptionist: answers, books and passes the tricky ones to you.
- Your own missed call list: free, but only works if someone clears it every morning.
Where does an AI receptionist fit in?
Anssay is not a telephony provider and it does not replace your number. As its site describes it, you keep your number and forward the calls you miss to Anssay, which answers in English, Tamil or Hindi, books into your calendar and hands anything tricky to you. You can see how the setup works and which businesses it is built for. Full details are on the pricing page. If you want to test it against your own missed calls, you can start a trial.
- Voice: Rs 4,999 a month excluding 18% GST, about Rs 5,899 with GST, includes 300 call minutes.
- Voice + Chat: Rs 6,999 a month excluding GST, about Rs 8,259 with GST.
- Trial: 14 days free, no card.
- Number: you keep yours.
