The USB line is for PC based calls and audio, where CS-700 is the speaker/microphone device.
The user starts with USB line active, an incoming SIP call on line 1, and an incoming SIP call on
line 2.

At the point, both SIP line 1, and USB line are in hold state.
answer 2
At the point, both SIP line 1, and USB line are in hold state, and SIP line 2 is in active state. The

At this point, all calls (USB, line 1, and line 2) are in a conference.
Hold only one call
Starting from the previous example, the user puts line 1 on hold.
hold 1
Because a held call cannot be in conference, this automatically removes line 1 from the
conference.
At this point, calls (USB, line 2) are in an active conference, and line 1 in on hold, outside the
conference.
Hold all calls
The user starts with all lines in conference.
hold all
