Specific resources can be reserved to guarantee a minimum level of service.
Resources reserved for a particular service (e.g., conferencing) cannot be used for another service
(e.g., Unified Messaging). i.e. You may want to reserve resources for OGM (Outgoing Message) to
ensure that recorded messages can be played to incoming callers.
The resources can be reserved for the following types of services:
• VoIP (G.711)
• Conference trunk
• Unified Messaging
• Two-way Recording
• OGM
