Hold (enquiry call)
An A – B connection is put on hold if one of the callers, e.g. user B wants to set up
an enquiry call connection with C.

Putting a call on hold
Detailed Description
Tab. 166 Hold (enquiry call)
If A is on hold and B hangs up before setting up a ringing or call connection to C, B's
terminal will ring continuously for 10 seconds. As soon as B picks up the handset,
he is again connection with A.
If A is on hold and B waits for more than 10 seconds before setting up a ringing or
call connection to C, B will obtain the busy tone. The return to the initial connection
is not automatic.
