How to Make PSTN Connectivity for Cisco Webex Calling Easy

How to Make PSTN Connectivity for Cisco Webex Calling Easy

In today’s busy hybrid workplaces, especially for organizations that operate globally, unified communications (UC) solutions like Cisco Webex Calling are no longer an optional extra. In fact, when it comes to boosting enterprise productivity wherever employees happen to be located, it’s fair to say that UC voice calling is really a must-have.

Indeed, this is exactly what we’re seeing playing out in the telecommunications arena, with UC as a service (UCaaS) solutions significantly expanding their customer base as enterprises everywhere recognize that the hybrid work model is here to stay.

Overcoming Infrastructure Challenges

However, the reality on the ground can be much more complicated, especially when many organizations have legacy investments in infrastructure, often with a mix of different PBXs and analog equipment. As a result, such organizations are likely to face a number of challenges around infrastructure maintenance, support agreements and compliance policies, to name just a few, when they migrate to UCaaS voice calling.

To take advantage of the incredible opportunities offered by the hybrid work revolution, many organizations are looking for quick and efficient ways to connect their Cisco Webex Calling solution to the PSTN to enable external telephony communication. And this is where AudioCodes session border controllers (SBCs) enter the frame.
