Setting up a call centre is less about buying software and more about a series of small decisions made in the right order: what the team will handle, how many seats you need, how calls reach you, where the system runs and how you will know it is working. This guide walks through how to set up a call centre in India step by step, whether you are starting a 10-seat helpdesk or moving a busy support team off a basic phone line.
Step 1: Decide what the call centre is for
Write down the jobs the team will do before you look at any product. Most call centres mix some of these:
- Inbound support: customers call with questions, complaints or service requests.
- Sales and enquiries: leads from ads, the website or WhatsApp that need a quick call.
- Appointments and bookings: hospitals, clinics, hotels, service centres.
- Follow-up calls: reminders, feedback calls and callbacks to missed callers.
For each job, note the languages callers use, the hours you must cover and what a good outcome looks like. This list drives every later choice: queues, IVR options, forms and reports.
Step 2: Estimate seats and peak hours
Look at your current call logs or phone bills and find the busiest hour of a normal week, not the daily average. Staffing is planned around that peak. If you have no data, start from the number of calls you expect per hour and the average length of a call, then use the method in Erlang C call centre staffing to turn that into a number of agents.
Plan for growth. Licences and seats can be added later, but your network, numbers and room layout should allow for it from day one.
Step 3: Choose how calls reach you
Callers need a number, and the call centre needs lines behind it.
| Option | What it is | Good for |
|---|---|---|
| SIP trunk | Phone lines delivered over the internet or a leased link | Most new setups, easy to add channels |
| PRI (E1) | 30 voice channels on a digital line | Sites with an existing PRI contract |
| Analog lines | Single lines connected through a gateway | Small teams or backup lines |
| Toll-free number | Free calling for customers, usually on SIP or PRI | Consumer helplines |
Many teams use a SIP trunk as the main route and keep a PRI or analog line as backup. Read SIP trunk in India and DID numbers in India for the details, and PRI to SIP trunk migration if you are moving from older lines.
Step 4: On-premise or cloud
Decide where the system will run. An on-premise server sits in your office or data centre, keeps recordings and customer data on your own hardware and works with local lines and gateways. Cloud hosting suits teams spread across many locations with no server room. The trade-offs are covered in cloud vs on-premise contact centre. Banks, hospitals and government offices often choose on-premise for data control.
Step 5: Get the network and desk setup right
Most call quality complaints are network problems, not software problems.
- Put voice on its own VLAN with QoS on the switches.
- Use a business-grade internet link, with a second link for failover if calls are critical.
- Give agents good wired or USB headsets with noise cancelling microphones.
- If agents use desk phones, PoE switches power them through the network cable. See PoE IP phones.
- For home agents, check their internet before go-live. See VoIP call quality for remote agents.
Step 6: Set up the contact centre software
This is where calls are queued, routed, recorded and reported. In Voxdial Contact Center the core setup looks like this:
- Agents: create a login for each agent.
- Inbound groups: one queue per team or service line, with music on hold, a waiting announcement, a timeout destination and an SLA target time.
- Agent priority: add agents to each group with a priority from 1 to 9, so experienced agents get calls first.
- Inbound DIDs and IVR: point each number at an IVR menu or straight at a queue.
- Dispositions and lead forms: the outcome codes agents pick at the end of a call and the fields they fill in. See call disposition codes.
- Break reasons: so you know why an agent is unavailable.
- Auto callback: missed and abandoned callers are called back within the window you set.
- Recording: switch recording on per group.
The agent console is a desktop app with a softphone, so agents can work with only a headset. It can also show your CRM in a tab and pop the caller’s record when a call arrives. See click to call CRM integration.
Step 7: Design the IVR and queues
Keep the menu short: three or four options, with the most common reason first. Send each option to its own queue and give callers a way to reach a person. Read IVR call flow design before you record prompts, and call queue management for waiting rules.
Step 8: Staff, train and write scripts
Hire for the languages your callers use. Give new agents a short call guide for each call type rather than a word-for-word script, and let them listen to recorded calls before they go live. See call centre scripts for templates.
Step 9: Plan supervision and quality checks
Supervisors need a live view and a way to help on calls. Voxdial’s wallboard shows calls waiting, service level, average handle time and abandoned calls, and supervisors can listen silently, whisper to the agent or barge into a call. Set up a weekly quality review with a short scorecard. See call centre quality monitoring.
Step 10: Add AI as a backup, not a front door
Keep people first. When every agent is busy or the office is closed, a BitVoice AI voice agent can answer in Indian languages, take down the request and hand the caller back to the next free agent with a summary. Callers who still wait can get a WhatsApp or SMS link to continue on chat.
Go-live checklist
- Test every number, IVR option and timeout path from a mobile phone.
- Make a test call to each queue with recording on, then play it back.
- Check that missed calls appear in the callback list.
- Run reports after day one and compare them with what supervisors saw.

FAQs
What do I need to set up a call centre?
You need phone numbers and lines (SIP, PRI or analog), contact centre software for queues, routing, recording and reports, a reliable network, headsets or IP phones, and trained agents with clear call guides.
How many agents does a new call centre need?
It depends on calls in the busiest hour, average handle time and your service level target. Use an Erlang C calculation and add shrinkage for breaks, training and leave.
Should a call centre be on-premise or in the cloud?
On-premise suits teams that want recordings and data on their own servers and already have local lines. Cloud hosting suits teams spread across many locations with no server room. Compare data control, line options and support before you choose.
Can a small business start with a few agents?
Yes. You can start with a handful of agents and one queue, then add agents, queues and numbers as call volumes grow.
