Unified Communication Solutions for the Modern Enterprise
Connect every desk, floor and branch on one intelligent platform. Cohesive Technologies designs, supplies and supports IP telephony, unified communications, conferencing, networking and surveillance for corporate offices, SMBs and large enterprises across India, Sri Lanka, Nepal and the Maldives.
Communication that scales with your business
Enterprises grow, restructure and open new locations — and their communication network has to keep pace without friction. Our unified communications approach brings voice, video, messaging, paging and security together into a single, manageable ecosystem, so your teams stay connected whether they are at a desk, on the factory floor, working remotely or spread across regional offices.
Every deployment is engineered around your workflow. We combine best-in-class hardware from globally recognised brands with the right IP-PBX platform, network backbone and support model — on-premise, cloud or hybrid — so the components work together to deliver measurable operational efficiency, lower call costs and room to expand.
From a five-user startup to a multi-site corporation handling thousands of calls a day, our pre-sales engineers help you specify the right stack, and our field teams handle installation, configuration and ongoing support.
End-to-end enterprise communication stack
Purpose-built building blocks that integrate cleanly — choose the ones you need today and add the rest as you grow.
Enterprise IP Telephony
Equip every workstation, reception and executive desk with reliable, feature-rich IP phones. Our portfolio spans entry-level to high-end colour handsets, DECT and Wi-Fi cordless phones, and rugged industrial telephones — all with HD voice, provisioning at scale and 36-month reliability you can standardise on across sites.

Unified Communications & IP-PBX
Replace ageing EPABX lines with a modern IP-PBX that unifies calls, voicemail, video, chat, mobility and contact-centre features. Deploy on-premise for full control, in the cloud for zero hardware, or as a hybrid — with softphone and mobile apps that keep staff reachable on any device, anywhere.

Business Conferencing & Collaboration
Make hybrid meetings effortless. Our conferencing solutions bring crystal-clear audio and full-HD video to huddle spaces, boardrooms and training halls — flexible enough to run any platform you already use, easy to install, and priced without the enterprise premium.

Enterprise Networking
A communication system is only as good as the network under it. Build fast, secure, wide-coverage wired and wireless infrastructure with cloud-managed access points, PoE switches and routers — supporting Wi-Fi 7/6, multiple SSIDs and VPN, all administered from a single pane of glass.

Enterprise communication questions
We provide a complete enterprise stack: business IP phones, IP-PBX and unified communications, video and audio conferencing, enterprise Wi-Fi and networking, IP surveillance with video analytics, IP paging and mass notification, door intercom and access control, VoIP gateways and IoT sensors — all from authorized global brands and supported by one team.
An IP-PBX is a business phone system that routes calls over your data network instead of traditional telephone lines. Enterprises use it to cut call and line-rental costs, unify voice, video and messaging, enable mobility and remote work through softphone apps, and scale users and sites easily without re-cabling.
Yes. We offer on-premise appliances for full local control and data residency, cloud/hosted PBX for zero hardware and easy multi-site rollout, and hybrid deployments that combine both. Our pre-sales team recommends the model that best fits your security, budget and scalability needs.
Our platforms scale from small offices of 5–50 users to large enterprises supporting thousands of extensions across multiple sites. Systems from Grandstream, Yeastar and Epygi can be clustered and expanded, so you start with what you need today and grow without replacing the core.
Absolutely. We design phased migrations that protect your existing investment — using VoIP gateways and ATAs to keep analog lines and PRI/E1 trunks working while you move users to IP in stages, avoiding disruption to day-to-day operations.
Yes. We deliver end-to-end services — consultation, configuration, professional on-site installation, extended warranty and ongoing technical support Monday to Saturday, 10 AM to 6 PM IST, across India, Sri Lanka, Nepal and the Maldives.
