Chapter 3 - Software Loading and Configuration

If FXO is selected, the Dialing Options Regeneration, Flash Hook Timer, and Ring Count

groups are enabled. Check with your local in-house phone personnel to verify whether your local

PBX dial signaling is Pulse or tone (DTMF). Then, set the Regeneration option accordingly. The

Flash Hook Timer allows you to eter the time, in milliseconds, for the duration of the flash hook

signals output on the FXO interface. The default setting is 600 milliseconds. The Ring Count

FXO window allows you to set the number of rings received on the FXO interface before the

MultiVOIP 400/800 answers the incoming call. The default setting is 2 counts.

Note: Zero (0) means that the MultiVOIP 400/800 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, you can copy that channel’s configuration by clicking the

Copy button and everything on the Interface tab will be copied to the designated channel.

7. Repeat the above step to configure the interface type for voice/fax channels 2 - 4 or 2 - 8.

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 400/800; 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.
