Create Off-Premise Extensions; Replace Expensive Tie Lines; Business Quality Voice - Multitech VoIP User Manual

Create Off-premise Extensions

Extend the reach of your PBX into home office locations.
Simply connect a VOIP solution to the PBX at the
corporate office, and another VOIP solution at the remote
office. Now, anyone can place calls to the remote office
by simply dialing an extension number.

Replace Expensive Tie Lines

A company that utilizes tie lines to connect branch office
PBXs to the corporate PBX can now use their own IP-based
Wide Area Network to complete the call.

Business Quality Voice

Independent tests of VOIP systems have shown that they
are perfectly capable of delivering "toll-quality" voice. The
actual voice quality your business will experience,
however, is affected by a number of factors: WAN
bandwidth (the higher the better), voice compression and
network conditions such as latency (average "travel" time
it takes for a packet to pass through the network). On a
private Intranet you can control all of these factors to
achieve near toll-quality voice connections. When using
the public Internet, you can control everything but the
latency factor. Latency, however, can be managed to
enhance your voice quality with a quality of service
guarantee from your ISP.
When network traffic is at peak levels, voice can be given
priority over data to ensure
consistently high voice
quality using the
Differentiated Services
(DiffServ) Quality of Service
(QoS) protocol. Other
features such as forward
error correction, bad frame
interpolation and dynamic
jitter buffers, can further
enhance voice quality.

"We made hundreds of
test calls using the
(MultiVOIP's) outside
lines, and most people
we called couldn't tell
that we weren't on a
standard long distance
line."
