# VM Port Capacity

## Purpose

The VM Port Capacity form sets the number of ports available for voice mail use. Each port supports a single Auto Attendant, RAD, or a voice mail session.

The maximum number of usable ports available varies by controller type. Refer the Engineering Guidelines and System Engineering Tool for more detailed recommendations based on performance limits of the installed hardware. Up to 120 ports might be selected for all platforms, but any number above the basic recommended value might be restricted based on the available resources.

Controller | Recommended Maximum Number of Ports Available
AX | 20
CXi II | 16
MXe III and EX | 30
All Server Variants | 12-120 (ISS, cMiVB) 12 VM or 120 total (VM + RADs) (Virtual)

Use this form when performing the following tasks:

- Program Embedded Voice Mail

## Conditions

- When more than 20 voice mail ports are programmed, an alarm is generated at the next system re-boot if additional DSP resources cannot be allocated.

- All other statically-defined DSP requirements take precedence over the 21+ ports so basic telephony will function.

- Each Record a Call session consumes one voice mail port.

- Each RAD greeting set consumes one voice mail port.

Number Of Ports | Enter a number between 1 and 120 as appropriate based on the controller type and available resources. For more information, see Engineering Guidelines. NOTE: Any change to this field requires a reboot of the MiVoice Business system to take effect. | 30 (x86 platforms Server-based variants of MiVoice Business that use x86 processors, MiVoice Business for Industry Standard Servers MCD-ISS), Virtual MiVoice Business, and cMiVB.
