The V-SERVER iPRO is a 4-analog-voice-port VoIP (voice over IP) and data integrated access device (IAD). These analog voice ports can be any of the following combinations: 4 FXS (or phone), 4 FXO (or line) or 2 FXS and 2 FXO. The iPRO becomes a VoIP gateway device when there are FXO ports available. The iPRO obtains Internet access through its WAN Ethernet port, which can be connected directly to a LAN, a Cable Modem or a DSL Modem . The iPRO also provides a LAN Ethernet port and built-in router function with DHCP , NAT and traffic priority routing control enabling users to built a private LAN behind the iPRO.
The iPRO has a 10BaseT Ethernet port for WAN connection and built-in DHCP and BOOTP clients. The WAN port also supports PPPoE (PPP over Ethernet) that is used widely in DSL or Cable Internet access. The port also serves as an interface between a private network and WAN when the iPRO's router function is enabled
The iPRO also has a 10BaseT Ethernet port for LAN connection. Using this port, user can connect one or more PC and other network devices behind the iPRO to give them data access to the Internet through NAT.
The iPRO's built-in router function and Network Address Translation (NAT ) protocol enable users to set up their own private LAN without a router. In this setup, voice calls, Fax and Data transmission go through the iPRO simultaneously. The iPRO's traffic priority routing feature, if enabled, gives the voice traffic higher priority than the data traffic and thus, ensures the voice quality.
The iPRO also provides access control and host exposure functions.
The Dynamic Dialing Administrator or DDA is software package that provides RAS (Registration, Admission and Status) server function and call routing server function to the V-Server iPRO and other TEK DigiTel products. Add-on packages to the DDA also provide software update, DDA Roaming, CDR Server , Calling Card server and DDA Voice Gateway functionalities.
Full version of the DDA is only available for the Linux operating System. However, the iPRO itself can provide some basic functions of the DDA, provided that the option is enabled by proper software key from the TEK DigiTel.
Call routing and call control in V-SERVER iPRO is achieved by either through TEK DigiTel's proprietary Dynamic Dialing Administrator (DDA) or a H.323 Gatekeeper.
A special ATPM (Address Translation and Parsing Module) mode is also available as an option for the user to manually configure the call routing table in the iPRO directly.
The latest version of iPRO firmware supports H.323 V3 (V4 is coming soon). In addition to work with a H.323 gatekeeper, the iPRO also has the ability to send or receive calls to/from a H.323 gateway directly without a gatekeeper. The iPRO can work with a variety of other vendors’ H.323 gatekeepers and gateways. Analog Port and Dialing Plan
The iPRO provides 4 analog phone ports that can be combinations of FXS and FXO. When a phone port is FXS, a phone set can be directly connected to the iPRO and user can make outgoing calls or receive incoming calls. When a phone port is FXO, a PSTN phone line can be connected to the port and through the line, a user on the PSTN network can receive calls or make calls from/to the Internet through the iPRO. If there is another iPRO connected to the Internet at a different geographical location, calls can be made between the 2 local PSTN telephone users through these 2 units.
The iPRO provides various dialing mechanisms for both DDA calls and H.323 calls to accommodate users requirements.
The iPRO also provides hunt group function and hotline (PLAR ) function.
The iPRO comes with user-friendly GUI configuration tools. Configuration can be done by the GUI tool through a PC directly connected to the iPRO's console port or through a remote PC via Telnet. Configuration to the iPRO also can be done through a SNMP manager. A centralized configuration and management server, the Configuration Server is also available with the DDA package. The iPRO also can be configured by keypad commands (DTMF commands ) from a touch-tone telephone set connected to the unit or by command line commands from any terminal emulator software either via local console or remote Telnet.
