When Intercom receives a call, you are presented with an Incoming call notice. It is then up to you whether you answer or reject it. The notice will contain the remote host-name or IP address and possibly the name of the person calling if he has set the appropriate variables. A typical incoming call notice looks similar to the following
intercom: Incoming call from shane@192.168.1.2. Use 'answer' to respond or 'hangup' to reject. |
As is stated in the notice, you may use the answer command to respond to the call or hangup to reject it. If the call is answered, the audio paths are immediately connected in both directions and you should be able to both speak to and hear the remote party.
