Multi-Tech Systems MVP120 manual Configuring the Master MultiVOIP

Chapter 4 - Configuring the Master MultiVOIP

15.The Ring Count FXO box enables you to set the number of rings received on the FXO interface before hanging up and releasing the line to another call. The default setting is 2 rings.

Note: Zero (0) means no incoming calls will be answered.

For FXO-to-FXO communications, you can enable a specific kind of FXO Disconnect Options: Current Loss, Tone Detection, or Silence Detection. Check with your in-house phone personnel to verify the type of disconnect to use. If current loss is checked, the VOIP will hang up when it detects a loss of current on the FXO (phone) port. For tone detection, select from the lists one or two tones that will cause the line to disconnect. The person hanging up the call must then press the key or keys that produce those tones to hang up a call. For silence detection, select One Way or Two Way, then set the timer for the number of seconds of silence before disconnect. The default value of 15 seconds may be shorter than desired for your application.

The Message Waiting Light check box must be selected on the originating and answering voice channel. This enables the number dialed to connect you to the appropriate voice channel, then output that number on the voice channel.

16.The Voice/Fax tab displays the parameters for the voice gain, DTMF (Dual Tone Multi-Frequency) gain, voice coder, faxing, and advanced features such as Silence Compression, Echo Cancellation, and Forward Error Correction.

17.You can set up the input and output voice gain so that the volume can be increased or decreased. Input gain modifies the level of the audio coming into the voice channel before it is sent over the Internet to the remote MVP120. Output gain modifies the level of the audio being output to the device attached to the voice channel. Make your selections from the Input and Output lists in the Voice Gain group. The valid range is +31dB to –31dB with a recommended/default value of 0.

You can also set up the DTMF gain (or output level in decibels - dB) for the higher and lower frequency groups of the DTMF tone pair. Make your selections in the lists in the DTMF Gain group. When the DTMF Out of Band check box is selected, the tones are passed via RTP packets, and the receiving VOIP reproduces the DTMF tones instead of passing them through like voice.

Note: Only change the DTMF gain under the direction of Multi-Tech Technical Support.

18.To change the voice coder, select the Manual option in the Coder group. Select the appropriate coder from the Selected Coder list.
