The note advises against duplicating the phone number inside the double quotation marks (" ") when it is already included within the double angle brackets (\textless{}\textgreater{}). This recommendation aims to avoid the display of unknown numbers caused by devices prioritizing SIP signaling information over locally stored contact information.}, }
