11. You can enable the voice/fax advanced features by selecting the Silence Compression, Echo
Cancellation, or Forward Error Correction check boxes.
The Silence Compression check box defines whether silence compression is enabled for this
voice channel. If silence compression is enabled, the MultiVOIP 800 will not transmit voice
packets when silence is detected, thereby reducing the amount of network bandwidth that is
being used by the voice channel.
The Echo Cancellation check box defines whether echo cancellation is enabled for this voice
channel. If echo cancellation is enabled, the MultiVOIP 800 will remove echo delay, which
improves the quality of sound.
The Forward Error Correction (FEC) check box defines whether forward error correction is
enabled for this voice channel. The FEC feature allows some of the voice packets that were
corrupted or lost to be recovered. FEC adds an additional 50% overhead to the total network
bandwidth consumed by the voice channel.
Note: After configuring a given channel, you can copy that channel’s configuration to any other
channel by clicking Copy. Everything on the Voice/Fax tab will be copied to the other channel.
12. The Billing/Security tab displays the parameters for automatic disconnection, billing options,
and dialing options.
13. You can set up billing options for inbound and outbound calls by selecting them in the Billing
Options group and then entering the charge in cents per number of seconds.
14. The Call Authentication option enables password protection for outbound and inbound calls on
the selected voice/fax channel. If you enable password protection on inbound or outbound calls,
you need to also enter a password of up to 14 numeric characters in the Password box.
15. The Automatic Disconnect option limits call duration to the number of seconds entered in the
Disconnect After box. The default value of 180 seconds can be changed to any other value up
to 65,535 (roughly 18.2 hours).
If your country/region is not the default USA, click the Regional tab and proceed to step 16.
Otherwise, proceed to step 17 to begin building your phone directory database.
