During recording a conversation you may wish to put the other person on hold. To do this simply click the 'Hold' button. To return to the call click 'Resume Call' again. When you place a call on hold, recording is stopped, when you take a call off hold a new recording is started.

It is also possible to simply use TRx as a basic on-hold service for a single phone line. Instead of clicking Record just use the Hold button. You can optionally hide the Record button from view by clicking in the main menu View->Record Button.
