Cloud Telephony & Voice Engineering

Tailor-Made PBX, SIP Trunking & Programmable Voice Deployments

Blutrain Private Limited stands up the entire calling backbone for the businesses we partner with. We assemble open-source PBX and softswitch platforms, light up numbers and voice through our in-house Twilio and Telnyx accounts, and route SIP trunks directly into the dialer, tracker and CRM your people already work in. Describe how your team calls, and we architect the rest.

The Short Version

A managed build, shaped to how your business actually calls

There's nothing here to download, license or wrestle into place. Blutrain Private Limited acts as the engineering team behind your phone system — we plan it, provision it and knit it together, then hand back a setup that simply works alongside the software you rely on today.

The carrier layer sits with us: numbers and programmable voice come out of our own Twilio and Telnyx accounts, travel over SIP into whichever dialer or call-tracking tool you use — 3CX, GoAutoDial, VICIdial, Dialics or something bespoke — and feed cleanly into your CRM or ERP so no data ends up stranded. Nothing gets ripped out, and there's no seat-based platform to rent forever.

What's In The Build

The full calling stack, delivered ready to run

We size every project against your call patterns, your existing software and the rules you operate under — then our team constructs and connects it all.

01

Bespoke PBX & Softswitch

Open-source PBX and switch platforms configured to push large volumes of simultaneous calls in both directions while staying stable under load.

02

Voice & DIDs On Our Accounts

With voice and numbers hosted on our Twilio and Telnyx accounts, you inherit full programmable-voice capability and never have to open a carrier account of your own.

03

SIP Trunks Into Your Dialer

We terminate robust SIP trunks straight into the dialer or tracker you operate today, whether that's 3CX, GoAutoDial, Dialics, VICIdial or an in-house build.

04

Numbers In Every Market

Local-presence and international DIDs set up to funnel inbound interest to the right people, no matter which country your callers sit in.

05

Hooks Into CRM & ERP

Calls and contact records flow into the CRM or ERP your business already runs, keeping agents and dashboards on a single source of truth.

06

Logging, Recording & Controls

Hardened webhooks and recording pipelines make sure every call, KPI and consent checkpoint is stored and easy to audit.

Fits Your Toolset

The build bends to your software, not the reverse

Already settled on a particular dialer or tracker? Perfect — we engineer the plumbing to meet it rather than pushing you onto something new.

Our Process

Four stages from kickoff to live traffic

STEP 01

Discovery

We take stock of your call load, the regions you dial, and the dialer, tracker and CRM already in play.

STEP 02

Stand-Up

Your PBX or switch gets built, and numbers plus voice are provisioned on our Twilio and Telnyx accounts.

STEP 03

Wire-In

SIP trunks, logging and recording slot into your dialer and lock onto your CRM or ERP.

STEP 04

Aftercare

Once you're live we stick around, tuning and maintaining the system as your volumes climb.

Where It Fits

The teams that get the most from this

Lead Generation

Outbound campaigns and localised callback numbers feeding your dialer, arranged to shave cross-border delay and stay within the rules.

Support & Service Desks

Dependable inbound routing and queue handling that let support crews soak up spikes without long waits or dropped calls.

Sales Floors

Voice fused with your CRM so reps track every call, contact and deal stage from a single screen.

Why Blutrain Private Limited

A custom system, taken off your plate

We build it, you use it

Every part — design, provisioning, integration — is handled by us. You end up with a running phone system, not a dashboard to figure out.

The carrier headache is ours

Voice and numbers ride on our Twilio and Telnyx accounts, so carrier applications and approvals never land on your desk.

Molds to your current tools

Whatever dialer, tracker, CRM and ERP you have in place, we plug into them as they are — the setup adapts to you, not you to it.

We stay past launch

Go-live isn't goodbye; we keep the system healthy and responsive as your operation grows.

FAQ

Fair questions, plain answers

Can I just sign up for this online?

No — it's fully done-for-you. We plan, provision and integrate each client's system around their own needs, so there's nothing to self-configure or purchase as a packaged product.

Who supplies the numbers and voice?

They come from our own Twilio and Telnyx accounts and reach your dialer or tracker over SIP trunking that we set up.

Does it plug into our existing dialer and CRM?

It does. We routinely link up 3CX, GoAutoDial, VICIdial, Dialics and custom dialers, then tie the whole thing into your CRM or ERP.

Which businesses benefit most?

Any lead-gen, support or sales team whose day revolves around inbound and outbound calling and who wants that calling properly joined up.

What about compliance?

Routing, recording and consent logic are engineered into the build to match carrier and industry norms. The final picture still hinges on where you operate and your own internal rules, which we plan around together.

Let's put the calling setup your business deserves in place

Walk us through the way your agents place and receive calls, plus the dialer, tracker and CRM you depend on — and we'll design a made-to-order system and see it through from first line to last.

Start a Conversation

Blutrain Private Limited is a telephony build and integration partner working with business clients on a project basis. Standalone phone numbers, calling minutes and dialer software are not products we sell on their own — the provisioning happens inside a managed engagement.
