0
Recordings in someone else's cloud
Recordings, call logs and reports stay on a server you own.

Downtime when broadband drops
Agents on your office network keep taking calls.
0
Hardware lock-in
Standard SIP throughout. Use your own phones, gateways or existing PBX.

Everything a support or sales floor needs, on one screen

Built on the same SIP engine that runs carrier platforms handling millions of calls a day, sized down for a five-seat office.

Line monitoring

See every line's status live, spread load across lines, and get an alert the moment one goes down.

Multilingual IVR

Menus in Hindi, English, Gujarati or any language you record. Route by time, caller or key press.

Queues and ACD

Skills-based, round-robin or longest-idle routing, with missed-call callbacks so no customer is dropped.

Browser softphone

Agents take calls in Chrome on the office network. A headset is all they need, and IP desk phones work too.

Outbound dialler

Preview and progressive dialling from your lead lists, with scheduling, retries and call outcomes tracked.

Recording and QA

Every call recorded to your own disk, searchable by number or agent, and scored against your checklist.

Live supervision

Listen, whisper or barge into any live call. A wallboard on the office TV shows the whole floor.

CRM screen-pop

The caller's record opens as the phone rings. Zoho, Salesforce, vTiger, Tally or your in-house software.

Reports and call logs

Real-time and historical reports per agent, line and campaign. Export to Excel in one click.

If your process needs it, we build it into your system

Off-the-shelf dialler boxes make you change how you work. Zero is maintained by the engineers who wrote it, so custom IVR logic, connectors and reports are a change request, not a new product.

“Our broadband went down in the middle of the Diwali rush and the phones kept ringing. That one afternoon paid for the system.”

Operations Head, textile wholesaler, Surat

“We asked for an order-status menu in Gujarati that reads from our billing software. It was live the same week, and we have not paid a per-minute bill since.”

Director, pharma distributor, Ahmedabad

Questions owners ask before buying

Do we have to change our phone lines?

No. Zero connects to the lines and PBX you already run. We check your setup during the site survey and tell you exactly what connects where.

What hardware do we need?

One small server, plus a gateway if your lines need one. We supply both, or install on hardware you already own.

How long does installation take?

Most offices are live within one week of the site survey, including configuration, testing with real calls and agent training.

Who looks after it once it is installed?

We do, 24x7. Updates, backups and fixes are handled remotely, with an engineer on site when a visit is needed.

Can we add seats or lines later?

Yes. Seats are a licence change, and new lines are configured remotely once they are connected.

Can we try it before buying?

Yes. The site visit includes a working demo on your own call flow, and you get a fixed quote before you commit to anything.
