Chapter 3 - Software Loading and Configuration
FXO window allows you to set the number of rings received on the FXO interface before the
MultiVOIP 200 answers the incoming call. The default setting is 2 counts.
Note: Zero (0) means that the MultiVOIP 200 never answers.
For FXO-to-FXO communications, you can enable a specific type of FXO Disconnect; Current
Loss, Tone Detection, or Silence Detection. (Check with your in-house phone personnel to
verify the preferred type of disconnect to use.) Enabling Tone Detection activates the
Disconnect Tone Sequence options. For Disconnect Tone Sequence, you can select from drop-
down lists either one or two tones that will cause the line to be disconnected; the person hanging
up a call must then hit the key(s) that will produce those tones. For Silence Detection, select
One Way or Two Way, then set the timer for the number of seconds of silence before disconnect.
Note that the default value of 15 seconds may be shorter than desired for your application.
E&M: If you are connecting to an analog E&M trunk on your PBX, then choose the E&M interface
option to enable the E&M Options group. Check with your local in-house phone personnel to
determine if the signaling is Dial Tone or Wink and if the connection is 2-wire or 4-wire. If Wink
signaling is used, then the Wink Timer is enabled with a default of 250 milliseconds. The range
of the Wink Timer is from 100 to 350 milliseconds. Consult with your local in-house phone
personnel for this timer setting.
Note: After configuring a given channel (1 or 2), you can copy that channel’s configuration by
clicking the Copy button and everything on the Interface tab will be copied to the other channel.
7. Repeat the above step to configure the interface type for voice/fax channel 2.
8. 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.
9. 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 in to the voice channel before it is
sent over the Internet to the remote MultiVOIP 200; and, 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 drop-down 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 drop-down lists in the
DTMF Gain group.
Note: Only change the DTMF gain under the direction of Multi-Tech Technical Support
supervision.
