# Set DTMF-to-PBX Protocols

This procedure describes how to set the following parameters for DTMF-to-PBX message waiting indicators:

- Dial strings (feature access codes) that the server must send to the PBX before or after the mailbox number in order to set message waiting indicators

- Places in the dial string at which the server must wait for dial tone from the switch while setting message waiting indicators

- Whether the server should send a message wait "on" request to the switch for every new message, or only when a mailbox with no new messages receives a message

To set DTMF-to-PBX protocols:

1. From the navigation tree, select Offline Configuration > Edit Offline Configuration. The Offline Configuration navigation tree opens.

2. When prompted to Duplicate Active Configuration, click Yes.

3. In the navigation tree, click Line Groups and then click Add.

4. In the Application list, select DTMF to PBX Dialer.

5. Configure the parameters on the Lines and DTMF to PBX Dialer tabs as described in the DTMF-to-PBX application parameters listing. Use the parameters on this tab to set the following optional settings:

   - Initial Dialtone Detect

   - Dial Tone Confirmation

   - Suppress MWI Updates

   - Wait for Dial Tone

   - Enable Alternate Code (to compensate for different directory and mailbox numbers)

6. Click Save.

7. In the navigation tree, select Commit Changes and Exit. Confirm the commit. Your changes are now saved to the duplicate (inactive) configuration. Configuration changes will not take effect until you have activated the inactive configuration.
