IP Telephony Features
·
Gatekeeper
The IP Office gatekeeper allows the registration of up to 384 IP extensions on the IP500, 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. Ensure that silence suppression configuration matches at both ends of the
SCN trunk for correct operation and also for improved sound quality.

Compression
IP Office supports a wide range of voice compression standards including G.711, G.729a and G.722.
The method of compression can be either automatically established on a call-by-call basis or
configured on an individual extension basis.
G.722 is supported on SIP Trunks, the 9600 Series sets, 96x1 Series Sets, B179 Conference Phones,
IP Office Video Softphone, 1100/1200 IP Phones and 3

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 telephones 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 T.38
IP Office supports the standardized protocol "T.38" for transporting FAX calls between IP Office and
SIP trunks or SIP endpoints. T.38 is only supported on IP500/IP500 V2 systems with IP500 VCM,
IP500 VCM V2 and or IP500 Combo cards. T.38 is not supported on Server Edition systems.
