IP Telephony and
Voice Over Internet Protocol ( VOIP )
IP
telephony on Avaya IP Office delivers real world
business benefits through both improved efficiency and
decreased costs. Avaya IP Office enables businesses to
adopt IP technology at a pace that is appropriate to
their needs allowing hybrid working with more
traditional telephony methods. IP telephony has the
advantage of allowing extensions to be deployed both
locally and remotely through the use of routers or VPN
services. IP Office supports both hard phones and
PC-based soft-phones.
By
supporting the H.323 and SIP standards, IP Office
provides standards-based interoperability between
systems and devices.
Multiple IP
Office systems
can be linked together
using a standard data network, providing feature
transparency and advanced applications such as
centralized voice mail and contact centre.
By
delivering advanced VoIP functionality today, customers
can buy IP Office as a traditional PBX, secure in the
knowledge that they can step up to a pure IP environment
when they want to - because it already delivers this
functionality. Alternatively, customers can buy IP
Office and implement it today as a pure IP system,
taking advantage of the cost savings associated with a
single communications infrastructure, as well as remote
management and the applications that they require.
IP Telephony Features
-
Gatekeeper
The IP Office gatekeeper allows the registration of
up to 16 IP extensions on the Small Office Edition,
190 IP extensions on the IP406, 360 IP extensions on
the IP412 and 272 IP extensions on the IP Office
500, less the number of analog and digital TDM
telephones already configured on the system.
-
Gateway
The Voice Compression Module provides the H.323
gateway function that allows IP extensions to make
calls to other non-IP devices. The maximum number of
simultaneous calls is limited by the number of
channels available on the Voice Compression Module.
IP Office must be fitted with an optional Voice
Compression Module to enable IP telephony.
-
Silence Suppression
Silence suppression is a technique used to make the
best use of available bandwidth, such as the
connection over which the caller is listening, not
speaking. Silence suppression works by sending
descriptions of the background noise, rather than
the actual noise itself, during gaps in conversation
thereby reducing the number and frequency of voice
packets sent on the network. Background noise is
very important during a telephone call. Without
noise the call will feel very unnatural and give a
perception of poor quality.
-
Compression
IP Office supports a wide range of voice compression
standards including G.711, G.729a and G.723.1. The
method of compression can be either automatically
established on a call-by-call basis or be configured
on an individual extension basis.
-
Fast Start
When fast start is supported by an IP extension,
this facility reduces the protocol overhead allowing
an audio path to be established more quickly.
-
Out of Band DTMF
When out of Band DTMF is configured on an IP
extension, the extension will signal to the other
end of the connection which digits need to be
regenerated by a local DTMF generator on behalf of
the sending IP extension. This is useful when
navigating external voicemail systems and
Auto-Attendants.
-
Direct Media Path
Direct Media Path allows the speech path between two
IP extensions (after call setup) to be routed
directly to each other. This allows the IP Office
system to free up voice compression resources after
establishing the end to end connection, allowing the
resources to be used in the most efficient way.
-
Auto-Create Extensions
IP Office can automatically create an extension
entry for new IP phones added onto the local area
network. In cases where the local area network is
not secure this facility can be disabled, but
simplifies installation of IP telephone systems
-
Fax Transport
Fax Transport allows fax calls to be routed over
VoIP trunks between IP Office systems on an IP
network using T.38
