20.1.1.2.3 Modifying a Conference
To modify an existing conference, INFO messages are used. Each INFO message carries
an MSCML request. The MSCML response is included in an INFO message back from the
device to the Application Server. It is possible to modify an entire conference (by issuing
requests on the Control Leg) or only a certain participant (by issuing requests on that
specific leg).
To modify the entire conference, a <configure_conference> MSCML request body is sent
in an INFO message on the Control Leg SIP dialog. Using this request, the Application
Server can modify the following attributes:
Reservedtalkers: If the Application Server sets a number that is lower than the initial
number requested in the INVITE, then the request is not granted. If the number is
higher than the initial number, the device sends a success response in the response
INFO.
Reserveconfmedia: If the necessary resources for applying Media Services on the
entire conference were reserved in advance, then by setting reserveconfmedia to Yes,
it is reserved. If set to No, the device can free the resource.
To modify a certain Participant Leg, a <configure_leg> MSCML request body is sent in an
INFO message on that leg SIP dialog. Using this request, the Application Server can
modify any of the attributes defined for the <configure_leg> request.
