Release 2.2 SP4 - An Overview of Features

FR12869 Mapping of ISUP Connected Number to SIP - Connected Line Identification Presentation (COLP)

Brief Description:

This feature adds the Connected Number parameter which is an ISUP parameter found in either the ANM or CON messages. On the ISUP side of the call, this implements the Connected Line Identification Presentation (COLP) supplementary service. The connected number parameter is sent in the backward direction to identify the number that is connected to a call. Because of changes in a call such as call redirection and call transfers, the connected number parameter may be different than the called party number. This feature interworks the connected number parameter between the ISUP and SIP protocols and is only supported for ITU ISUP.
