# Voice Mail Message Waiting Indicator Programming Guidelines

When programming voice mail, follow the guidelines below to ensure that users get a message waiting indication when they have new messages in their mailbox.

## About Voice Mail and Message Waiting Indicators

- To send a message waiting indication, the voice mail system hunts for a free port starting from the highest port to the lowest port.

- For systems that are configured with 20 ports, the voice mail system will not look for ports above port 20.

- For systems that are configured with 30 ports, the voice mail system will not look for ports above port 30.

- The port that it picks must be in the Voice Mail hunt group.

- Ensure that the Number Of Ports in the VM Port Capacity form matches the number of voice mail ports programmed in the VM Ports form.

## Programming guidelines

- All voice mail ports must be in a hunt group of type VoiceMail (voice mail hunt group). You can have one voice mail hunt group for the system, or multiple voice mail hunt groups.

- If Record-A-Call is enabled: the voice mail ports assigned to Record-A-Call must be assigned to a hunt group of type Recorder as well as to the voice mail hunt group. Do NOT remove these ports from the voice mail hunt group.
