With more than 18 million Webex Calling users worldwide and 30 million more on Cisco Unified Communications Manager (CUCM),1 there’s no doubt that Webex is a serious player in the UCaaS arena.

However, while the platform is packed with enterprise-grade features and backed by a rock-solid SLA, adopting Webex as a fully-fledged business voice solution and enabling seamless connectivity with the PSTN can still be a challenge – especially for customers with legacy systems, complex needs or global footprints.
But what if there was an easier way? Well, now there is.
Certified to Simplify
AudioCodes is now a fully certified provider for Webex Calling. In fact, we hold three key certifications:

Certified Calling Provider
Delivering end-to-end PSTN voice solutions via Cloud Connect.

Cloud Connect Enablement Provider
Certified Mobile Calling Provider (Webex Go)
These certifications, along with our deep voice expertise and flexible deployment options, allow partners to bring a complete, scalable business phone system to life for their Webex customers – without reinventing the wheel.
Real Results, Real Use Cases
Whether it’s enabling global PSTN connectivity, managing hybrid environments or integrating legacy analog devices, AudioCodes has you covered. Here are just a few ways our solutions deliver value:
- PSTN Flexibility for the Real World: A partner needs a multi-tenant SBC for its Webex Calling service, but strict security policies require SBCs to be deployed locally – not in the cloud. No problem. With AudioCodes, they can offer both cloud-hosted and on-prem SBCs, keeping IT teams and compliance officers happy while supporting a smooth Webex rollout.
- Local Breakout Made Easy: When regulations or carrier limitations call for PSTN breakout in multiple countries, AudioCodes’ Webex Local Gateway solution steps in. Our centrally managed, certified session border controllers can be easily monitored and orchestrated – even across dozens of sites.
- Voice AI Meets Webex Contact Center: Want to add conversational IVR, call screening, virtual agents and agent assist to your Webex Contact Center offering? AudioCodes can help you integrate seamlessly with leading AI services, improving customer experience (CX) and delivering a serious competitive edge.
- Analog Doesn’t Mean Outdated: Still supporting analog devices like fax machines, intercoms or legacy phones? Our analog gateways make it easy to bring these devices into the Webex Calling environment, ensuring zero disruption and full compliance, while consolidating management under one platform.
- Built for Migration Your Way: Migrating from CUCM or another PBX to Webex Calling? AudioCodes lets you do it your way. Our co-existence model allows both platforms to run in parallel, helping users transition gradually without breaking workflows. And with BYOC flexibility baked in, you can keep existing contracts while modernizing your voice stack.
