Method for providing custom ring-back tones
摘要:
A method is provided for providing customized ring-back tones to callers on a wireline network such as a public switched telephone network having an advanced intelligent network or a VoIP network. When a call request is received from a calling party to connect to a called party through a wireline telephone network it is determined if the calling party is identified in a screening list for the called party. If so, then a customized audible ring-back tone is played to the calling party until the called party is connected to the calling party or until the call request is terminated.
