Why Switch to NAK for Your Telephony Needs?

The PSTN Switch-Off is an opportunity to rationalise your telephony infrastructure and move to advanced technology that offers additional benefits.

Reduced Costs

Improved User Experience

Minimal Migration Effort

You may already be affected by these
common telephony challenges:

Expensive Calling Plans:

Microsoft Calling Plans for Teams is a premium offering you don’t need for delivering voice services to your telephony users.

While straightforward to enable, using voice capabilities in Microsoft Teams end-to-end comes with a hefty price tag.

Poor Usage Analytics:

In call centre or service desk environments, the management information surfaced by Microsoft Teams falls short of the analytics required to measure and manage agent performance.

As Peter Drucker once said, “If you can’t measure it, you can’t manage it.”

Inflexible Infrastructure:

Traditional analogue telephone lines require legacy switchboard infrastructure to support multiple handsets or users.

Modern Voice over Internet Protocol (VoIP) solutions quickly scale to support multiple users without investment in difficult-to-manage telephony infrastructure.
