Enabling Call Waiting

The Call Waiting feature enables busy FXS endpoints connected to the device to accept an
additional (second) call. If an incoming IP call is designated to a busy port, the called FXS endpoint
hears a call waiting tone (several configurable short beeps) and can view the Caller ID of the
incoming call (for Bellcore and ETSI Caller IDs). The calling party hears a call waiting ringback
tone. The called party can accept the new call using hook-flash and can toggle between the two
calls. To indicate call waiting, the device sends a SIP 182 (Call Queued) response. The device
identifies call waiting when a 182 (Call Queued) response is received.
