Every call begins with a security code that must be verbally confirmed between the users to ensure the call has not been intercepted. Once all contacts have passed the manual identity verification, the green “SECURED” icon will appear. Tapping “SECURED” will also allow the user to reject the verification and end the call.
ChatMail allows for up to two calls ongoing at any given time, and you can swap between calls as needed and merge the calls together for high quality and secure three-way calling. Calls made on WiFi are free and unlimited.
