This service provides the conference of an existing held call (heldCall) and another active
call (activeCall) at the controlling device. The two calls are merged into a single call and
the two connections at the conference controlling device are resolved into a single connec-
tion in the connected state. The pre-existing CSTA connectionID associated with the
device creating the conference are released, and a new callID for the resulting conferenced
call is provided.

which is active at the controlling device and is to be
conferenced with the heldCall. The deviceID in activeCall
must contain the station extension of the controlling device.
[mandatory - partially supported] a connection identifier
specifies the resulting new call identifier for the calls which
were conferenced at the conference controlling device. This
connection identifier replaces the two previous call identifiers
at that device.
[optional - supported] specifies the devices on the resulting
newCall. This includes a count of the number of devices in the
new call and a list of up to four connectionIDs and up to four
deviceIDs which define each connection in the call.
• If a device is on the DBS, the extension is specified.
• If a party is off the DBS, then its assigned dynamic trunk
identifier is specified.
