Clear communication is crucial; poor call quality can quickly lead to frustrated employees and unhappy customers. That’s why Webex Calling is continually investing in the infrastructure and technology needed to deliver unmatched call quality. Today, let’s take a closer look at three key areas where Webex has made significant advancements to elevate your call experience:
Webex AI Codec, transforming your audio experiences
Poor call quality often stems from challenging network conditions that cause packet loss—something we’ve all experienced in hotel rooms or on mobile phones in remote areas, where voices come through choppy and hard to understand.
Our latest industry-first innovation, the Webex AI Codec, addresses these scenarios with a single, end-to-end solution for speech enhancement and highly resilient communications, ensuring crystal clear audio anywhere, on any device, under any conditions. Webex AI Codec intelligently adjusts the bitrates and redundancies, when encoding audio packets – becoming an industry first innovation and providing a real differentiating experience for our users.
Let’s check out an example. The call below was made with the industry-standard Opus codec, and as you’ll see in Webex Diagnostics, there’s around 80% packet loss. The result? Audio that’s garbled and impossible to understand.
The call below was made in the same conditions with the Webex AI Codec.
You can immediately hear the difference—even under the same challenging network conditions, the call with Webex AI Codec is clear and easy to understand. The improvement is night and day!
Webex AI Codec is being rolled out globally for Webex Calling and Meetings on the Webex App on desktop and mobile devices. When you experience poor network quality with over 30% packet loss, Webex AI Codec will be triggered automatically.
HD Voice, crystal clear audio on both ends of the call
In addition to our groundbreaking work that mitigates the impact of packet loss, we’ve made innovations that make calls sound better by enriching voice and eliminating background noise. Last year we unveiled another industry-first innovation called HD Voice, which combines two important technologies:
- Audio Intelligence, which eliminates distracting background noise from calls
- Wideband audio, a Webex-exclusive innovation that uses AI to enrich narrowband PSTN audio to wideband, providing a clearer more intelligible calling experience
Best of all, HD Voice works on both ends of the call, even if the person you’re speaking with isn’t a Webex Calling user. This is an essential feature for agents, admins, and receptionists that spend much of their day speaking to external callers like customers, suppliers, and partners.
Global data center footprint
Webex Calling is powered by a robust global network, with 17 data centers and media points-of-presence (PoPs) strategically placed around the world. This extensive infrastructure has delivered 99.999% availability over the past 24 months and ensures that our customers enjoy high-quality and reliable calls across 170+ markets worldwide. In July, we expanded our platform with a new media PoP in the United Arab Emirates, and we’re not stopping there—additional data centers are set to go live later this year. This ongoing investment underscores our commitment to delivering seamless communication experiences, no matter where your business operates.
As businesses increasingly rely on seamless and reliable communication, Webex Calling continues to push the boundaries of what’s possible with innovative technology and a global infrastructure designed to deliver exceptional call quality. From AI-driven noise removal to intelligent codecs that adapt in real time, we’re committed to making every conversation crystal clear, regardless of network conditions or device. With our ongoing investments and industry-first innovations, you can trust Webex to keep your business communications strong and your teams connected, no matter what challenges arise.
