The hold command automatically removes calls from conference, but if you just send the hold
command for line 1, line 2 will remain in conference. It is best practice to send the join
command to split the conference first.
join 1 0 2 0
hold 1
hold 2
Resume calls and re-establish the conference
Both lines need to be in active state before they can be joined. Note, leaving two lines in active
state without joining them will produce undefined telephony behavior.
resume 1
resume 2
join 1 1 2 1
Remove calls from conference and leave one call active
A single line cannot be put into a conference with the join command. Similarly, a single line
cannot be left in a conference with the join command. Commands join 1 1 2 0 and join 1 0 2 1
will also remove both calls from the conference.
Similarly, if no calls are in the conference, join 1 1 2 0 does not change the line 1 status to
indicate that it’s in conference. If no calls are in the conference, join 1 0 2 1 does not change
the line 2 status to indicate that it’s in conference.
Following is the correct way to remove calls from conference.
join 1 0 2 0
At this point both calls are connected to the speaker and microphone locally, but they do not
send audio to each other. Note, leaving two lines in active state without holding either or both
will produce undefined telephony behavior.
hold 2
At this point, line 1 remains active, and line 2 goes on hold.
