VoIP Gateway for Traditional PBX
SETU VFXTH helps an organization to integrate new
communication technologies to its existing infrastructure. Using SETU
VFXTH, a traditional PBX system can connect to VoIP networks. With new
networks being integrated, communication happens using the most
cost-effective networks. Features like Automatic Number Translation,
Programmable Access Codes and host of other advanced functionality,
enable users to access new networks without changing their dialing
habits.
SETU VFXTH can be connected to a traditional PBX in
two ways. Firstly, the FXS ports of SETU VFXTH can be connected to the
FXO ports of the PBX. On dialing prefix assigned in the PBX, the user
can access these FXS ports to make VoIP calls. Secondly, the FXS port
(SLT port) of the PBX can be connected to FXO port of the SETU VFXTH.
PBX users can access VoIP network connected to SETU VFXTH by dialing the
FXS port number of the PBX.
PSTN Gateway for IP-PBX
SETU VFXTH enables the IP-PBX users to make calls
to the PSTN network. It assures users the most cost effective route of
IP for all their calls to PSTN till the last mile of termination.
SETU VFXTH gets registered to an IP-PBX as a
client. Registering multiple gateways to a single IP-PBX, allow the
IP-PBX users to relay calls over IP and use the local fixed-line
connectivity. Organizations operating widely in varied locations can
significantly benefit from such a set-up.
Network Two TDM PBXs over the IP Network
Matrix SETU VFXTH helps an organization to network
multiple locations over the IP network. SETU VFXTH forms the gateway to
establish seamless connectivity between two locations, using existing
PBX systems. Users can make calls to other location using standard
telephony instrument connected to the PBX. Extensions of the PBXs can
call each other directly without going to the operator. This also avoids
the need of changing the habituated dialing habits, with the gateway
taking care of it.
SETU VFXTH can be used for connecting multiple
locations. It can be used for seamless calling by connecting FXO port of
SETU VFXTH to FXS port of the PBX. When the extension of the PBX calls
the FXS port of the PBX (connected to FXO port of SETU VFXTH), with the
intelligent call routing mechanism, the call is routed to the SETU VFXTH
at the other location over the IP network. Once the call reaches the
other location the caller can call any extension of the PBX or access
the local PSTN network to save long distance call cost.
Multi-Site connectivity
Matrix SETU VFXTH facilitates easy and low cost
communication between geographically spread, multi-branch offices.
A multisite connectivity can be established through
the existing IP network. SETU VFXTH connects to existing infrastructure
with its varied interfaces. SETU VFXTH located at various branch
offices can be registered to the IP-PBX at the head office. This extends
the IP-PBX connectivity to the various branch offices. SETU VFXTH can
be connected to the local PSTN network via FXO interface. This allows
all other registered users of the IP-PBX to access the local PSTN
network where the SETU VFXTH is installed, reducing the call cost
significantly.
Allowed and Denied Numbers
Allowed and Denied Lists are used to restrict
dialing of long-distance and international numbers. A number is blocked
if its prefix matches with any entry in the Denied Lists. On the other
hand, a number is allowed to go through if it matches with any entry in
the Allowed List. This provides flexibility of allowing only specific
numbers, blocking all others.
Automatic Number Translation
This feature allows the Gateway to translate
the number string dialed by the user to a format compatible with the
network through which the call is to be routed. So, the user can dial
numbers freely without worrying about the network through which the call
will be routed.
Call Progress Tones and Rings
The gateway offers flexibility of programming
call progress tones and ring cadence to match the standards of the
country of installation. Country Specific Call Progress tones like Dial
Tone, Ring Back Tone, and Busy Tone etc. can also be programmed.
Caller Line Identification and Presentation (CLIP)
SETU VFXTH can provide Caller Line
Identification Presentation (CLIP) on FXS ports. Analog CLIP protocols
such as DTMF, FSK ITU-T V.23 and FSK Bellcore 202A are supported by the
gateway.
CLI based Call Routing
A call can be routed to a fixed number from the
CLI presented on SETU VFXTH. When a call lands on the network ports of
the SETU VFXTH, it detects the CLI, verifies the CLI and routes the call
to the predefined number.
Call Detail Record (CDR)
SETU VFXTH can store details of 2000 calls in
its memory. Call reports can be generated using filters like source
port, destination port, calling number, called number, date, time and
duration.
Day Light Saving
The Real Time Clock (RTC) of the SETU VFXTH
moves forward or backward automatically in tune with the Day Light
Saving requirement of the country where it is installed. The options
like Week-Day-Month or Date-Month are provided to move the clock forward
and backward automatically on the specified day, date and time.
Fax over IP (FoIP)
The Matrix SETU VFXTH user can send and receive
Fax over SIP account, when the FAX machine is connected to the FXS
port. The SETU VFXTH supports FoIP using T.38 Vocoder and Pass-Through.
FXO
The gateway offers FXO port to connect the PSTN
network and route incoming calls to VoIP network or the extensions. It
can also be used to connect extension of a PBX to network two PBX over
VoIP.
Network Port Parameters
Web Jeeves of SETU VFXTH provides a
configuration menu to program its network port parameters to match the
LAN addressing scheme of the installation site. Parameters such as IP
address, subnet mask, connection type, etc., can also be programmed
through a telephone instrument connected to the system.
Peer-to-Peer Calling
SETU VFXTH support VoIP calls, between two
locations without going through a proxy server. Fixed IP addresses of
various locations can be programmed in the Peer-to-Peer table of the
gateway to avail this facility. The gateway supports 500 entries in the
Peer-to-Peer table. Numerical dialing codes can be defined to simplify
the calling between various locations.
PIN Authentication
The gateway uses PIN Authentication to verify a
caller’s identity before routing the call from one network to another.
It is an important feature that prevents unauthorized usage.
Prefix to Domain Name Conversion
This feature enables the conversion of a
numerical code dialed by the user to a domain name. It helps the SIP
service provider to understand and route the call to the required
destination.
Remote Held/Transfer
The user of SETU VFXTH can keep a called person
at remote end on hold or even transfer the call to a third person. This
feature can be activated only if the device at the called end supports
Call Hold/Call Transfer feature.
SIP Accounts
A maximum of 32 SIP accounts can be programmed
and each FXS user can be assigned one of the SIP accounts for outgoing
calls. Dynamic allocation of SIP account is also possible using the Dial
Plan. These SIP accounts can be from multiple service providers or all
from a single service provider.
Universal Routing
Universal Routing allows the gateway to route a
call received from one network to another based on the routing
mechanism programmed in the system. A source port can be programmed for
more than one destination port so that if one port is busy, the call can
be routed through another port.
VLAN Tagging
A Virtual Local Area Network (VLAN) may be
defined as a group of LANs that have different physical connections, but
which communicate as if they are connected on a single network segment.
VLANs increase overall network performance by grouping users and
resources that communicate most frequently with each other.
Web Based Programming
Matrix SETU VFXTH incorporates Built-in HTTP
server and web pages for easy configuration. This Web based programming
feature allows a user to configure the gateway from any part of the
world, once connected to the IP network
