AT&T 2.1.1 manual Release R1V1 and R1V2 Software Limitations, Music On Hold

System 75 and DEFINITY G1 Initial Implementation

Release R1V1 and R1V2 Software Limitations

The R1V1 and R1V2 versions of System 75 have several limitations that affect the operation of AUDIX Voice Power. One of these limitations includes possible effects of the Music On Hold feature for all R1V1 and R1V2 systems.

The other limitations apply only to integrated systems. For R1V1, the limitations include the inability of attendants to access AUDIX Voice Power via the DCP line, the inability of all subscribers to access AUDIX Voice Power via the DCP line to retrieve messages, and a less-reliable interface between the switch and the AUDIX Voice Power system. For R1V2 systems, the limitations are related to the inability of the attendant to access AUDIX Voice Power via the DCP line.

Music On Hold

If your switch is configured for Music On Hold, you must upgrade the switch to R1V3, R1V4, or G1. Otherwise, callers will hear and be confused by several seconds of music prior to hearing the greeting from the AUDIX Voice Power system that they were expecting.

Accessing the DCP Extension (R1V1)

Callers cannot access voice mail by calling the DCP extension. The DCP interface is used only for the Call Answer Service. A hunt group of one or more channels configured for the Voice Mail Service must be set up for access to voice mail. This is non-integrated Voice Mail Service. Subscribers must enter their extension as well as their password to retrieve their messages. The Class of Restriction feature of System 75 must be used to prevent subscriber access to the DCP number. However, subscribers must have access to the Voice Mail hunt group.

AUDIX Voice Power software that interfaces to System 75 R1V1 software transfers calls from the DCP line to one of its analog lines. The System 75 software does not allow calls from an attendant console to be transferred.

Because of this, an attendant cannot transfer a caller to a subscriber and wait for AUDIX Voice Power to provide Call Answer Service for the caller. The attendant must either drop the call after the transfer is performed, or return to the caller when the ringing stops. In addition, if the attendant wants to leave a message for a subscriber, he or she must call a separate group of one or more channels configured for the special service “attendant_ca” which provides non-integrated Call Answer Service. The attendant must enter the extension of the person receiving the message.
