[asterisk-users] "hint" for Hold

[Chan Kwang Mien]

Hi,

"hint" is used to monitor the status channels by using extensions in
the dialplan.

When an IP phone holds a call, there aren't any extensions sent to Asterisk.

Does anyone know how I could monitor "Hold" ?

For example, when an IP phone holds an existing call, the button on the
phone that monitors the Hold blinks.

regards,
