Cisco Systems VG204 Manual De Usuario

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 

Three-party conferencing provides a three-way conversation between three call parties. The voice

Protocol (RTP) streams
