Cloud Telephony for call center: Scaling CX with BICS
clock 15 mins read

Modern contact centers are in crisis! With customer expectations at an all-time high and communication volumes increasing exponentially, traditional phone systems are struggling to keep up. Cloud telephony is increasingly being adopted as a scalable, resilient alternative, as businesses seek to modernise customer support.

According to Uptime Institute, 16% of data-center operators say their most recent outage incurred a cost of over $1 million. Whether it is dropped calls or system crashes during peak traffic, the limitations of legacy phone setups are no longer tolerable.

These systems, which rely on physical hardware and outdated PBX infrastructures, lack the scalability, visibility, and reliability to support a modern, omnichannel customer experience. 

This results in poor customer satisfaction scores, frustrated agents, and mounting operational costs.

The solution lies in the cloud. Specifically, cloud telephony offers call centers the agility, resilience, and intelligence needed to thrive in today’s digital-first world. At the forefront of this shift, BICS is leading with the enterprise-grade cloud telephony platform engineered to eliminate these pain points. 

We leverage global reach, carrier-grade infrastructure, real-time business phone analytics, and seamless integration with call center software to achieve this result.  

In this article, we dive deep into cloud telephony and what BICS offers businesses to streamline their communications. 

 

Why traditional phone systems fail high-volume operations

Legacy phone systems were never designed for the fast-paced, globally distributed call centers we have today. 

These call center software rely on outdated PBX hardware, rigid configurations, and isolated regional providers, making it hard to scale, integrate, or maintain basic voice reliability.

Even a single hour of downtime can cost enterprises millions,  making traditional, on-premise phone systems a risky liability for high-volume operations.

Traditional infrastructure cannot match customer expectations for 24/7, omnichannel, seamless support. 

You will face problems like:

  • Dropped calls due to fixed capacity limits
  • Lack of real-time visibility into voice traffic or quality
  • Geographic inflexibility for scaling across regions
  • High TCO due to hardware upgrades, maintenance, and fragmented vendor contracts

 

Introducing cloud telephony 

Cloud telephony is a phone system, a call center software that operates through an internet connection. 

It allows businesses to move their phone services to the cloud, eliminating the need for physical equipment like landlines and extensive on-premise hardware. 

This technology is often referred to as a Voice over Internet Protocol (VoIP)-based hosted PBX solution.

Beyond just voice calls, cloud telephony is a type of Unified Communications as a Service (UCaaS), meaning it integrates various communication systems and collaboration tools. 

This includes phone calls, video meetings, instant messaging, Customer Relationship Management (CRM) integration, and other business processes within a single, unified platform.

 

How does cloud telephony work?

Cloud telephony leverages a virtual architecture that connects VoIP endpoints through the internet to a cloud communication provider, which manages all call routing, number provisioning, quality control, and compliance.

Here’s how a typical flow looks:

  • Call is initiated via an agent, IVR, or customer device.
  • SIP trunk connects the call to the cloud telephony provider.
  • The provider routes the call globally, selecting the best path and gateway.
  • The call reaches the recipient via PSTN, VoIP, or mobile networks.
  • Call metadata and quality stats are captured in real time.

This means your business doesn’t need to manage physical hardware, carrier interconnects, or region-specific regulations; it’s all handled via call center software.

Top platforms like BICS Cloud Telephony exceed expectations even further with global routing, SIP interconnects in most countries in the world, and self-service portals like MyNumbers for provisioning.

 

How does Cloud Telephony help businesses? 

Migrating to cloud telephony offers numerous advantages for businesses:

At BICS, maintaining uninterrupted service is critical. That’s why we deploy globally distributed, high‑availability Session Border Controllers (SBCs) configured in active–standby pairs.

Each primary SBC is continuously mirrored by a standby peer (or redundant hardware module), enabling near-instant failover should any component go offline.

These SBC clusters also perform health checks via “heartbeat” signals over dedicated networks, ensuring rapid detection and switchover.
This architecture is combined with teams working in a 24/7 follow‑the‑sun model, ensuring our voice backbone is always resilient, scalable, and secure.

Powerful reporting and analytics

Cloud services provide clear insights into team communication and performance through business phone analytics features like call volume, call duration, traffic patterns, and missed calls.
