Doesn’t do incoming calls, and routes outgoing ones – Recorder Review

The app only records outgoing calls, not incoming ones (due to apple’s hardware not allowing calls to be tapped). Outgoing calls are US-only, because it forwards the call through a server that records the call (thus an internet connection is required). Unfortunately when I tried using the app I got a 502 error. The developers have a good support page with FAQ, but no mention of that error nor what it means.
