Zoom Phone is the cloud telephony service from Zoom Communications. Besides ordinary phone calls, it covers SMS and MMS, voicemail, videomail, call recordings and transcripts. Administrators configure it through the Zoom web portal and use it alongside Zoom Workplace. It is delivered as a cloud service (SaaS).
Zoom Communications is a publicly listed company headquartered in San Jose, California, and falls under US jurisdiction, including the CLOUD Act. Paying customers can choose where content such as call recordings, voicemails, transcripts and messages is stored, for example Germany or Switzerland; Zoom also lists the US, Canada, Australia, Brazil, Japan and Singapore, among others. Call logs stay in the region where the account was provisioned, and account and operational data stay in the US. Recordings are first processed temporarily in the SIP zone where the device is registered. The product is proprietary and not open source. For a European organisation, the choice of storage region is therefore relevant, but the provider remains a US company.
