Workshop: Sustainability through innovative technolog

On Wednesday, June 4, 2025, Daniél Kerkmann, Expert Lead at OpenTalk, will hold an exciting workshop:

“From theory to practice – OpenTalk under the hood & Cisco in real-world operation”

The workshop will show how OpenTalk works as an open, modular platform – explained in an understandable way and demonstrated in a practical manner. Daniél Kerkmann will guide participants step by step through the process of a video conference: from the invitation to media transmission, with a focus on architecture, services, and protocols such as SIP, TURN, and WebRTC.

He will then move on to practical applications: In a live demo, Daniél will demonstrate how old Cisco Room Kits and desk phones with video functionality can be integrated into OpenTalk via SIP – sustainably, efficiently, and with surprising potential for real-world use.
