Auto Configuration
SETU ATA can be configured automatically from a central location. The configuration details like Registrar Server Address, Authentication User ID, User Password are stored in the central server. When user connects SETU ATA to the network, it automatically downloads its configuration using TFTP. This plug-n-play feature requires the user to enter only the server address provided by the service provider.

Automatic Number Translation
Setu ATA supports multiple port types, FXO, FXS and SIP. Whenever a number is dialed from any of these ports, gateway routes the call to the desired destination port as per the routing mechanism defined for that port. In certain cases, the dialed number string is not understood by the network through which the call is to be routed, so by using Automatic Number Translation the dialed number string is translated into a number that is understood by the network or ITSP to reach the desired destination port.

Auto PSNT Fall back
Setu ATA can be interfaced to the PSTN using FXO Port. This port is used to dial out numbers to the PSTN Network. When Routing the calls from PSTN number to SIP trunk, the Ethernet Link may go down or the SIP Account used is not registered. So the call will not be routed through SIP and you will get error tone to avoid this you can use this feature Auto PSTN Fall Back through which the call will be automatically get routed through the alternate FXO Port.

Calling Party Control (CPC)
CPC is required to prevent hanging of the FXS port when it is connected to a device like an answering machine, a voice mail system, etc. When a call is released from the other side of the Internet, the Matrix SETU ATA can propagate this call release on the FXS in the form of Calling Party Control (CPC) signal. The device senses this signal and frees the FXS port.

Call Progress Tones and Rings
Matrix SETU ATA supports programmable tones and rings to match those of the country where it is installed.

CLIP
SETU ATA allows users to program the FXS ports for any of the three CLIP protocols - DTMF, FSK ITU-T V.23 and FSK Bellcore 212A.

Dial Plan
Matrix SETU ATA provides a list of programmable numbers or part-numbers with the preferred SIP account for each entry. When the user dials a number, the SETU ATA finds the matching number using the “best-fit” logic. It then uses the SIP account given against this matching number to make that call. This ensures lowest cost for all the outgoing calls.

Fax over IP (FoIP)
The user can send and receive Fax over SIP account, once a Fax machine is connected to SETU ATA. The SETU ATA supports FoIP using T.38 UDPTL and Pass Through

FXO
SETU ATA FXO port should be connected to the PSTN or PBX so that the user can make PSTN calls from this.

MAC Cloning
When replacing the existing hardware with other, you can simplify the installation process by copying the MAC Address of your existing PC. In such case, you do not need to delay the SETU process by informing your service provider of newly installed equipment.

Multi-Stage Dialing
Multi-Stage dialing is useful for ATAs connected to a SIP Server used for networking PBX of multiple sites. The user can dial the entire number string, both the destination number and extension number of the destination PBX together. The ATA will split the string into two stages, and dial out the destination number first and on receiving the answering signal the extension number. This ensures hassle free access to PBX extension

Incoming Call Routing
Calls arriving from any SIP account can be routed to either one or both FXS ports.

Jeeves (Web Based Programming Tool)
Flexible and user friendly windows based software, Jeeves, helps in programming the features through web browser. This web based programming feature helps users to configure the SETU ATA from any part of the world once it is connected with the IP network.

Peer-to-Peer Calling
SETU ATA can make and receive calls from other VoIP users without any Registrar or Proxy server. Numbers and IP addresses can be assigned to the other VoIP users to provide direct access across the network. For Peer-to-Peer calling, SETU ATA provides two options - (i) Peer-to-Peer Number Dialing (ii) IP Address Dialing. Organizations having multiple locations like branch offices and factories can use this feature to provide direct dialing between these end-points.

Phone Book
Frequently used numbers can be programmed in the internal phone book with 99 entries. The user can dial these numbers by using short codes in place of the complete, long numbers.

PPPoE
Matrix SETU ATA supports PPPoE client and hence can be used with any xDSL modems.

PIN Authentication
Authentication required to connect from one network to another, is called PIN Authentication, and is used to authenticate the caller to prove his identity before the call is being processed by SETU ATA to avoid the possibility of malicious calls and to avoid misuse of its services

Quality of Service (QoS)
Matrix SETU ATA supports TOS and DiffServe to facilitate improved voice quality.

Router
Basic routing capabilities are provided so that LAN port packets can be transferred on WAN port. This allows the user to browse the Internet and check his emails while making and receiving VoIP calls.

SIP Accounts
Two 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 Dial Plan.

Speech Volume Setting
SETU ATA allows user to set the transmit and receive gain to improve the quality of speech.

STUN
This capability allows Matrix SETU ATA to work behind asymmetrical NAT.

Supplementary Services
SETU ATA supports supplementary service like Call Hold, Call Waiting, Call Toggle, Call Transfer, Call Forward, Conference, Caller ID, DND and Making Another Call. These are the Service Provider dependant features.

Surface Mount Technology (SMT)
The Surface Mount Technology is the current semi-conductor packaging technology that offers reduction in real estate resulting in less heat generation and low power consumption. This is in turn improves reliability.

System Log
Syslog is one of the protocols used extensively for sending debug messages on IP network. It is a client/server protocol that uses UDP as transport protocol for debugging process. SETU ATA has in-built syslog client that enables it to send the debug messages. Logging has several benefits which include troubleshooting, security and system administration. Debug messages are sent to remote server on IP network for finding and reducing the number of bugs or defects from a system.
