HOLD is not a standard supplementary service for Euro-ISDN PRI, nevertheless some PBXs support call hold and retrieve.

HOLD is not defined in Q.SIG but corresponding procedures are available.

Call transfer is only possible if path replacement works.

In a Q.SIG environment, the feature is also called "Simple Dialog".
