ITG-S844 is suitable to
migrate from existing TDM digital PABX or Telephone
call to make VoIP calls without changing existing call scenario, cable layout
and dial plan. Moreover, it provides flexible routing
call to local PSTN company
or to VoIP service provider. When ITG-S844 is failed
or lost of power, PSTN and PABX will be connected directly (bypass mode) to backup PSTN
incoming call to PABX.
It is also suitable for PSTN line Backup in IP-PBX FXO
gateway application. A configurable routing table is built-in ITG-S844 to provide flexible routing
rule among IP call, FXS and FXO port automatically.
Higher Capability VoIP mixed FXS and PSTN Gateway
■ Build-in 4 ports FXS and 4 ports FXO for flexible routing management.
Enhanced VoIP service
■ Design 1-WAN and 4-LAN for diverse networking environment. Provide Call Detail Record to extend the service into enterprise client, Call-Shop, Apartment and etc.Suitable for Enterprise use, rich-features are designed to interwork with IP-PBXs for small andmiddle enterprises.
Carrier-grade features are supported and tested to be fully interoperable with leading Soft-Switches.
Interoperability tested with marketing leading IP-PBX
■ Be compatible with marketing leading IP-PBX, such as Alcatel, Lucent, Siemens etc.
Physical Interface
■ Ethernet port (RJ-45, 10/100 base-T)
■ 1-WAN port, for connect to Internet via router, ADSL modem (ATU-R), or switch hub directly.
■ 4-LAN port, for PC or other network devices connection.
Telephony port (RJ-11)
