Hello 3CX, As this is a SIP security exposure issue, would you please consider addressing it with heightened urgency? MyPhone - Hide Outbound Rules, Route, "Prepend" value from appearing when dialing a phone number. When dialing using MyPhone, the value that is entered into Outbound Rules, Rule Name, Route, Prepend clearly appears in the dial string for everyone to see. However, the Prepend value is confidential, and in fact, is a secret code required by the VoIP Provider for SIP Registration. Can MyPhone be slightly modified to hide the display of the value in the Prepend field, please? Thanks!
