Basic Telephone Service

In addition to the computer connection, two analog devices such as a telephone, FAX, modem, or answering machine can be con- nected using the two POTS interfaces on the rear panel (RJ-11 jacks labeled 1 and 2 with a diagram of a telephone above the jack).

Supplementary Voice Services

Supplementary services such as call forwarding, caller ID, call re- turn, call holding, three- or six-way conference, call transfer, call rejection, and call waiting are fully supported by the Express XRT on a touch-tone telephone. These services are available only if in- cluded in the ISDN line configuration and are implemented using the standard commands provided by the telephone company.

Call Waiting

Call Waiting permits one voice call to be placed on hold while an- swering another voice call. Use the flash-hook to place the active call on hold and answer an incoming call. Hanging up terminates both calls. The call waiting tone can be disabled and enabled us- ing a touch-tone phone as follows:

Disable call waiting: Press ** 0

Enable call waiting: Press ** 1

Conference Calling

Conference Calling (also known as three-way calling) permits a conversation between three parties, each at different locations.

During a voice call, the call waiting tone signals a second incom- ing call. Flash-hook to place the first call on hold and answer the incoming call. Flash-hook again to retrieve the first caller. A third flash-hook conferences all three parties.

To enable Call Conferencing, dial **2 before dialing the telephone number. This enables the Flash Hook button on your telephone to conference up to six people together. The dial code is only neces- sary when S37=0, when S37=1, or when the Flash Hook button will conference by default.
