CALLER LINE IDENTIFICATION PRESENTATION (CLIP)

SPEAK UP offers free Caller Line Identification Presentation (CLIP). With this feature, caller's phone number appears on your handset display, so you know who's calling before you answer.

In the same manner your phone number is displayed when you call someone. In some cases, however, when users choose to hide their number or when they are calling from a network that doesn't support this feature, the caller's number will not be displayed.
