Call Waiting

If a calling party places a call to another party and the other party is engaged in a call, and the called party has call waiting, the party receiving the call can suspend the current telephone call and switch to the incoming call. For example, when caller A is engaged in a call with Caller B, a second call coming in to caller A from caller C will cause caller A to hear the call-waiting tone (one tone with 300ms duration), which indicates a second call. Caller A should be able to use the softkey transfer button to answer the waiting call and then use softkey transfer to switch between the two calls.

To configure call waiting on the voice gateways, use the same commands and configuration shown in “Call Transfer” section on page 4-11.

Three-Party Conferencing

Three-party conferencing provides a three-way conversation between three call parties. The voice gateways along with CUCM support three-party conferencing using Cisco IOS software to perform G.711 (ITU-T standard for audio companding) software mixing for up to three Real-time Transport Protocol (RTP) streams

To configure three-party conferencing on the voice gateways, use the same commands and configuration shown in the “Call Transfer” section on page 4-11.

Caller ID

Caller ID transmits a caller's number to the called party's telephone during the ringing signal.
