The voicemail server has restrictions on the number of channels it can use for different types of outgoing calls that it can make. These limits are separate for each of the call types. When a limit is reached, further calls of that type are delayed until one of the existing calls is completed. These limitations are not controlled by Voicemail Channel Reservation settings.

• Outcalling can use up to 5 channels at any time.

• Conference center invitation calls can use up to 5 channels at any time.

• Callback calls can use up to 2 channels at any time.

• Alarm calls can use up to 2 channels at any time.
