Defining AVC-Based Conference Profiles
As the fields are modified the Preview changes to show the effect of the changes.
For example:
26 Click the Network Services tab.
The New Profile - Network Services dialog box opens.
Registration of conferencing entities such as ongoing conferences, Meeting Rooms, Entry Queues,
SIP Factories, and Gateway Sessions with SIP servers is done per conferencing entity. This allows
better control on the number of entities that register with each SIP server.
Selective registration is enabled by assigning a conference Profile in which registration is configured
to the required conferencing entities. Assigning a conference Profile in which registration is not
configure to conferencing entities will prevent them from registering.
By default, Registration is disabled in the Conference Profile, and must be enabled in Profiles
assigned to conferencing entities that require registration.
