1.2.4 Resource Allocation

Each MSI-supported board has 32 resources managed by the application.

Notes:

1. For details on the functions below, see the Modular Station Interface API Library Reference.
2. The channel selector of the party does not affect the resource usage.
3. Conferencing is supported on Intel® Dialogic® Integrated (DI) Station Interface boards and MSI/SC-Global Series boards only. Each of these hardware platforms has different conference size limits.
For DI boards: refer to the Release Notes for applicable conference size limits.
For MSI/SC boards: a conference is limited to eight parties. A monitor is counted as one of the eight parties.
4. For MSI/SC boards: when zip tone support is enabled, 31 conferencing resources are available.
