Data and Voice Note Some ISDN service providers might charge a lower rate for an ISDN line that supports only data applications. If you do not require voice capability on your ISDN line, provision the line for data application support only. Table C-1 describes the data and voice application features. Table C-1 ISDN BRI Data and Voice Applications Feature Subaddressing Speech/3.1-kHz audio-bearer capability Multiple subscriber numbers (MSN) Call hold and retrieve Call waiting Call bumping Call transfer 3-way call conferencing Description Provides locally addressed terminals within a specific ISDN access area. Enables use of terminal equipment that supports voice applications. Examples of this type of equipment are ISDN telephones and terminal adapters. Enables the use of multiple directory numbers on the same ISDN line. Each piece of terminal equipment on the same ISDN line can then be assigned its own directory number. Enables a call in progress to be put on hold and then retrieved. During a voice call, enables the call waiting tone to be generated when a second voice call is received. When two data calls are in progress and ACO is provisioned on the ISDN line, the router can be configured to either ignore a voice call or disconnect a data call to accept the voice call. (Also referred to as voice priority.) Transfers an active call to another telephone number. Adds a third party to an existing call. C-2 Cisco 700 Series Router Installation Guide
