MultiVOIP Quick Start Guide
When receiving fax packets from a remote MultiVOIP, it is
possible for individual packets to be delayed or received
out of order due to traffic conditions on the network. To
compensate for this effect, the MVP120 uses a Jitter
Buffer. The Jitter Value box allows the MVP120 to wait a
user-definable period of time, in milliseconds, for delayed
or out of order fax packets. The range of allowable Jitter
Values is 0 to 400 with a default of 400 milliseconds.
If you do not plan to send or receive faxes on the voice/fax
channel, you can disable faxes in the Fax group.
9. You can enable the voice/fax advanced features by
clicking (checking) the silence compression, echo
cancellation, or forward error correction options.
The Silence Compression option defines whether silence
compression is enabled for the voice channel. If silence
compression is enabled, the MVP120 will not transmit
voice packets when silence is detected, thereby reducing
the amount of network bandwidth used by the voice
channel.
The Echo Cancellation option defines whether echo
cancellation is enabled for the voice channel. If echo
cancellation is enabled, the MVP120 will remove echo
which improves the quality of sound.
The Forward Error Correction (FEC) option defines
whether forward error correction is selected for the 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.
10. The Billing/Misc tab displays the parameters for auto call,
automatic disconnection, billing options, and dynamic jitter
buffer.
