DTMF Options

These options apply to Direct, CCI-22, FOR-22, TEL-14 interfaces and LQ SIP.

This applies to all port types with the DTMF options, that is interfaces with a telephony element to them. They are also used to control access to the system by the external caller.

The setups for outgoing calls are configured on the MVX-A16 card which controls the outgoing DTMF on TEL-14 interface modules.

 

Access prompt

Controls whether the port sends DTMF access prompt tones and may be enabled or disabled. This allows the incoming caller to receive access prompts. The default is disabled.

 

Assign DTMF codes

Assigns a DTMF selector code to a specific audio path. This allows the incoming caller to make various preselected links within the matrix by entering a specific code.

 

Enable DTMF passcodes

This enables the use of passcodes that are set up using the Configuration > Preferences > System Access Codes tab. Up to eight DTMF passcodes can be set up for a system and each passcode can be enabled for a port using a drop-down menu.

When enabled incoming callers must enter a 4-digit passcode before being allowed access.

 

First code only

If this is enabled DTMF tone detection is disabled after the first valid DTMF code has been received. Default is disabled.

Note: Only on TEL-14.

 

Accumulate DTMF codes

This field controls whether only one DTMF selector code can be used (disabled) or whether multiple DTMF selector codes can be used. The default setting is disabled.

When enabled this allows the incoming caller to make multiple routes by dialing multiple codes.

 

One-digit codes

If this is set enabled DTMF selector codes are limited to a single digit or the hash (#) and asterisk (*) characters. The default setting is disabled.
