In the Cisco CallManager Express environment, busy tone is not detected when a call is made to an engaged extension
In the Cisco CallManager Express environment, if a call is made from one IP phone to another that is busy, then no busy tone or engage tone is heard. This is a normal behavior when ephone-dns are configured as dual-line. This means that each line instance has two channels available. This is needed for things like full consult transfer and conference. The normal behavior with dual-line configured is that if a call is already active on the first channel, and another call is made to that extension, it rings on the second channel.
If you want a busy tone to be returned when an extension is busy on the first call, you can configure huntstop channel. This output provides an example:
ephone-dn 1 dual-line number 20873 pickup-group 200 name Dave Pandit
