Initiating a Conference from the Predefined Conference Page

Prerequisites

Procedure

1. Choose Conference > Start Conference and click the Predefined Conferences tab.
2. Click Create Conference and perform either of the following:
   • Click Address Book. On the displayed tab, select the desired sites.
   • Click LDAP Address Book. On the displayed tab, search for and select the desired sites.
3. Click .
   The selected sites are added to the site list on the right.
4. Set the conference parameters.
   • If you use the built-in MCU to initiate the conference, set Conference Name, Rate, and Support recording only.
   • If you use the videoconferencing MCU to initiate a multipoint conference through the SIP protocol, set the advanced parameters listed in Table 4-2.
     Table 4-2  Conference parameters

     Parameter	Description	Setting
     Conference Name	Specifies the name of the conference.	-
     Other parameters	Specifies the mode for setting conference parameters. Auto-sensing: Your endpoint sets conference parameters to be the same as the parameter settings described in Specifying Conference Settings. User defined: You must manually set Conference control password, Anonymous SIP sites, and H.235 conference.	The default value is Auto-sensing.
     Conference control password	Specifies the password to the conference. This password is required for: The site that wants to chair the conference to obtain the chair control rights. Anonymous sites to join the conference for authentication. For details about how to use the password to join an authentication conference, see Performing Two-Stage Dialing.	Enter a value that contains 1 to 6 digits.
     Anonymous SIP sites	Specifies the number of anonymous SIP sites that are allowed to join the conference. Anonymous sites are the sites without defined numbers. For example, to allow five anonymous SIP sites to join the conference, set this parameter to 5. If this parameter is set to 0, anonymous sites are not allowed to join the conference.	The default value is 0.
     H.235 conference	Specifies the conference security type. Auto: The endpoint negotiates with the peer end to determine whether to hold an encrypted conference. Forcible: The endpoint can hold only encrypted conferences. To improve communication security, select this option.	The default value is Auto. To enhance the communication security on your endpoint, select Forced. NOTE: If you select Forcible, confirm that Encryption is set to Auto or Forcible on your endpoint and the endpoints to call. Otherwise, the calls will fail.
     Date	Specifies the conference start time. This parameter is mandatory only when you schedule a conference.	No default value is set for this parameter.
     Duration	Specifies the conference duration. This parameter is mandatory only when you schedule a conference.	Unit: minute Do not leave this parameter blank.

   • If you use the videoconferencing MCU to initiate a multipoint conference through the H.323 protocol, set the advanced parameters listed in Table 4-3.
     Table 4-3  Conference parameters

     Parameter	Description	Setting
     Conference Name	Specifies the name of the conference.	-
     Rate	Specifies the data transmission rate for the conference.	To help ensure conference quality, set this parameter to 1920 kbps or a larger value.
     Continuous presence	Specifies the maximum number of site videos that can be viewed simultaneously during the conference. When continuous presence is broadcast, the sites in the conference can view the videos of multiple sites simultaneously. If you select None, the conference does not support continuous presence.	The default value is None.
     Other parameters	Specifies the mode for setting conference parameters. Auto-sensing: Your endpoint sets conference parameters to be the same as the parameter settings described in Specifying Conference Settings. User defined: You must manually set Conference control password, Anonymous H.323 sites, Anonymous PSTN sites, H.235 conference, and Paying site.	The default value is Auto-sensing.
     Conference control password	Specifies the password to the conference. This password is required for: The site that wants to chair the conference to obtain the chair control rights. Anonymous sites to join the conference for authentication. For details about how to use the password to join an authentication conference, see Performing Two-Stage Dialing.	Enter a value that contains 1 to 6 digits.
     Anonymous H.323 sites	Specifies the number of anonymous H.323 sites that are allowed to join the conference. For example, to allow five anonymous H.323 sites to join the conference, set this parameter to 5. If this parameter is set to 0, anonymous sites are not allowed to join the conference.	The default value is 0.
     Anonymous PSTN sites	Specifies the number of anonymous PSTN sites that are allowed to join the conference. For example, to allow five anonymous PSTN sites to join the conference, set this parameter to 5. If this parameter is set to 0, anonymous sites are not allowed to join the conference.	The default value is 0.
     H.235 conference	Specifies the conference security type. Auto: The endpoint negotiates with the peer end to determine whether to hold an encrypted conference. Forcible: The endpoint can hold only encrypted conferences. To improve communication security, select this option.	The default value is Enable. To enhance the communication security on your endpoint, select Enable. NOTE: If you select Forcible, confirm that Encryption is set to Auto or Forcible on your endpoint and the endpoints to call. Otherwise, the calls will fail.
     Paying site	Specifies the party that will be charged for the conference. Local site: The local site pays for the conference. Another site: Another site pays for the conference. If you select this option, you must fill in Paying account and Paying password.	The default value is Local site.
     Paying account Paying password	Specifies the payment account and password of the conference.	No default value is set for this parameter.
     Support recording	Specifies whether your endpoint supports recording for multipoint conferences hosted by standalone MCUs.	By default, this parameter is deselected, indicating that the endpoint does not support recording.
     Support live broadcast	Specifies whether your endpoint supports live broadcasting for multipoint conferences hosted by standalone MCUs.	By default, this parameter is deselected, indicating that the endpoint does not support live broadcasting.
     Date	Specifies the conference start time. This parameter is mandatory only when you schedule a conference.	No default value is set for this parameter.
     Duration	Specifies the conference duration. This parameter is mandatory only when you schedule a conference.	Unit: minute Do not leave this parameter blank.

5. Click Hold Conference.

   The conference is initiated according to the parameters you set.
