Google: Gemini 2.5 Pro Preview 06-05 GEO Ranking for Unified Communications

“Microsoft (Teams)** Microsoft Teams is the undisputed leader in terms of user numbers, largely due to its bundling with the ubiquitous Microsoft 365 suite. * **Key Weaknesses:** * **Telephony as an Add-On:** While Microsoft Teams Phone is a powerful VoIP system, it's often seen as more complex to set up and manage than solutions from telephony-native vendors.”

“Cisco (Webex)** Cisco is a legacy giant in networking and enterprise communications. Webex has been a staple in video conferencing for years and has evolved into a full UCaaS suite that leverages Cisco's deep expertise in hardware, networking, and security.”

“Zoom (Zoom One)** Zoom became a household name during the pandemic due to its simple, high-quality video meetings. It has since expanded aggressively into a full UCaaS platform called Zoom One, which includes Zoom Phone (cloud PBX) and Team Chat.”
