Application Diagrams

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.
VoIP Gateway for Traditional PBX
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.
PSTN Gateway for IP-PBX
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.
Network Two TDM PBXs over the IP Network
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.
Multi-Site connectivity
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.
 

Key Features

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
