Telecommunications (not Art. 28 GDPR)
SIP/telephony connectivity is provided by easybell GmbH. Telecommunications services are largely not processing on behalf within the meaning of Art. 28 GDPR: the provider is itself the controller for data relating to the circumstances of the telecommunication (e.g. billing data; cf. EDPB Guidelines 07/2020 on controller and processor) and does not take knowledge of the content in order to preserve telecommunications secrecy (§ 3 TDDDG). The telephone system and LiveKit instance are operated in-house.
