Cloud Calling and Webex Calling: Enterprise Voice, Reimagined
Cloud calling is the replacement of on-premises PBX infrastructure with voice services delivered over the internet — enabling calls from any device, any location, under centralised management.
Webex Calling is Cisco's enterprise-grade cloud calling platform, combining UCaaS, CCaaS, and CPaaS capabilities in a single solution, and the only platform in the market supporting on-premises, cloud, and hybrid deployment simultaneously. For Indian enterprises navigating data residency requirements, legacy infrastructure investments, and the demands of hybrid work, that distinction matters more here than almost anywhere else.
Why Webex Calling? Why Now?
- The only platform supporting on-premises, cloud, and hybrid deployment simultaneously — no forced migration, no architectural compromise.
- One of only two vendors globally recognised by Gartner across UCaaS, CCaaS, and CPaaS — your entire communications stack on a single platform.
- Dedicated Indian data centres in Mumbai and Chennai, with in-country storage of call recordings, CDRs, and voicemail — fully TRAI-compliant.
- Native integration with Webex Meetings, Messaging, and Contact Centre for unified employee and customer experience workflows.
- Lower total cost of ownership — no on-site PBX hardware, no maintenance contracts, and no separate platforms for calling, contact centre, and CPaaS.
- End-to-end encryption, AI-powered call intelligence, and compliance with India's telecom regulatory requirements — built in, not bolted on.
For three decades, enterprise telephony ran on a simple principle: own the infrastructure, control the call. That model served its purpose. But hybrid work, distributed teams, and the accelerating pace of AI-driven communication have made it inadequate, without making it obsolete.
The answer most vendors offer is a clean break. Rip out the PBX, move everything to the cloud, start fresh. It is the right answer for some organisations. It is the wrong answer for a hospital managing nurse station continuity across a power failure, a bank holding call recordings under RBI guidelines, or a manufacturer running a plant floor where a WAN outage cannot be permitted to take down internal communications.
Webex Calling takes a different position. It is the only enterprise calling platform in the world that natively supports on-premises, cloud, and hybrid deployment — not as a migration path, but as a permanent architectural choice. Cisco describes Webex Calling Hybrid as an industry first: the ability to keep call control on your existing Cisco Unified Communications Manager while selectively layering in cloud capabilities — AI receptionist, cloud analytics, advanced call queues, mobile integration — without disruption, without a forklift migration, and without surrendering the operational reliability your business depends on.
This is not the same as what Microsoft Teams or Zoom offer. Direct Routing in Teams is a PSTN connectivity method — cloud call control remains the system of record. Zoom Node is a survivability tool that activates only when cloud connectivity fails. Neither gives you genuine, permanent hybrid call control as an architectural choice. Webex Calling does, and it is the only vendor in the market supporting all three deployment models simultaneously.
What UCaaS, CCaaS, and CPaaS Actually Mean for Your Business
Most enterprise calling conversations stop at UCaaS — unified communications as a service. Webex Calling goes further. It is the foundation of a unified customer and employee experience stack spanning three categories that most vendors address with three separate platforms, three separate contracts, and three separate points of failure.
UCaaS is your internal communications backbone: calling, meetings, messaging, unified across devices and locations.
CCaaS is your customer-facing layer: contact centre capabilities, intelligent call routing, agent management, and real-time analytics.
CPaaS is the programmable layer beneath both: enabling your teams to embed communications into business workflows, automate customer journeys, and build the interactions your industry demands.
Webex is one of only two vendors in the world recognised by Gartner in all three Magic Quadrants simultaneously, UCaaS, CCaaS, and CPaaS. For a CIO evaluating total cost of ownership, that consolidation has real consequences: fewer vendors, fewer integrations to maintain, fewer points of failure, and a single accountability chain when something goes wrong at scale.
India's First. And the Blueprint for What Follows. Customer Success.
When Lohia Corp Limited, one of India's most respected manufacturing conglomerates, decided to modernise its enterprise communications, it chose Webex Calling. It was India's first Webex Calling deployment in the manufacturing sector.
The challenges were exactly those that define the category: legacy infrastructure embedded across plant locations, compliance requirements that could not be compromised, and a workforce that needed to stay connected across factory floors, offices, and remote sites without disruption.
" Following the successful implementation of Webex, the transformation was evident. Our collaboration and connectivity significantly enhanced our operational efficiency."

The Lohia Corp deployment is not a case study we reference to fill a page. It is the proof of concept for every manufacturer, every multi-site enterprise, and every organisation that has been told cloud calling requires a clean break from what came before. It does not.

Why This Matters More in India Than Almost Anywhere
India's enterprise telephony landscape is not uniform. A GCC in Bengaluru deploying Webex Calling from day one is a fundamentally different conversation from a manufacturing group in Pune migrating 800 seats off a legacy Avaya system, with five branch locations and last-mile connectivity that cannot be taken for granted.
Cisco has established a dedicated Webex Calling infrastructure in India, hosted in Mumbai and Chennai data centres, with in-country storage of call recordings, call detail records, voicemail, and audit logs. For organisations subject to data residency requirements under India's telecom regulatory framework, this resolves the most common objection to cloud calling adoption. Connections are supported through Airtel, Tata Communications, and Tata Teleservices — the PSTN providers Indian enterprises already work with.
Proactive has operated across both conversations — and most of the ones in between. We understand SIP trunking complexity in Indian deployments, the practical realities of Airtel and Tata Communications PSTN integration, and what TRAI compliance actually requires in the field, not in a datasheet. When we say we have replaced EPABX systems with Webex Calling across manufacturing, BFSI, and healthcare clients in Delhi, Mumbai, Bengaluru, Pune, and Hyderabad, there is a success story behind each one.
Proactive Data Systems: The Deployment Partner That Stays
Selecting Webex Calling is a platform decision. Deploying it well, across multiple sites, legacy infrastructure, and a workforce that has used the same phone system for a decade, is an engineering problem that requires someone who has solved it before.
Proactive is a Cisco Preferred Partner, one of a very small group in India holding all five Cisco portfolios: Security, Networking, Collaboration, Cloud and AI, and Services. Our Collaboration practice is not a bolt-on to a networking business. It is a core competency, staffed by certified engineers who have designed and migrated cloud calling and Webex Calling environments across manufacturing, BFSI, healthcare, IT/ITeS, and GCC clients across India.
We offer Managed Cloud Calling as a standing service, not a post-deployment support contract, but active management of your Webex Calling environment: provisioning, monitoring, number management, quality analytics, and escalation ownership. When something fails at 11 pm before a board meeting, you have one number to call.
From discovery and design through migration, training, and long-term managed voice services, Proactive ensures that your move to cloud calling and Webex Calling delivers what was promised and keeps delivering.
