Our feature is designed for people to comply with the law in jurisdictions requiring two party consent. It shows a notice for every inbound and outbound call where call recording will be enabled. It also has a per-contact toggle for enabling it instead of simply being either enabled or disabled. We also plan to offer the option to have it automatically disclose the call is being recorded.
There are other ways to record calls such as enabling speaker mode and using another device to record the audio. It's similar to apps trying to prevent users from taking screenshots. It fundamentally doesn't work.
