While Knowlarity has been a Superb in cloud telephony, many businesses are now exploring alternatives that offer better flexibility, cost-efficiency, and advanced features. Some of the main reasons include:

Pricing Concerns

Compared to other service providers, Knowlarity’s pricing is much higher, whereas many telephony providers deliver advanced features at a lower cost. This makes startups and SMBs especially inclined to seek affordable alternatives.

Limited Advanced Features

Modern businesses need AI-driven call analytics, advanced reporting, call log, routing, monitoring and seamless integrations with CRM or helpdesk tools. Since Knowlarity lacks some of these modern capabilities, many businesses are switching to other providers that offer richer feature sets.

Customer Support Challenges

Some users have reported that Knowlarity’s customer support service often faces delays in resolution and has limited availability. As a result, companies prefer providers that offer 24/7 dedicated support to ensure smooth business operations.

Scalability Issues

As organizations expand globally, they need flexible solutions with instant (toll free, virtual and local) number provisioning in multiple countries. Some businesses find Knowlarity less flexible in scaling quickly compared to other providers.

Service Reliability & Uptime

Global Coverage

Modern businesses often seek a communication partner with global reach and scalability. However, Knowlarity’s services are mostly restricted to India, which pushes many companies to explore providers with global presence.

Customization Needs

Today’s businesses want tailor-made telephony solutions. Alternatives that provide APIs, modular features, and customizable workflows are preferred.
