Chapter 4 Configuring Voice
Configuring Calls
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.
