Optional SMS termination8.Support IMEI changeable9.Quad band, IMEI changeableOverviewA VoIP GSM Gateway (GoIP) bridges voice communications between the GSM and the IP networks seamlessly.In principle, it consists of a GSM module and a VoIP module. With a SIM card installed, the GSM module registers to the GSM network for voice and SMS services.GoIP comes with various models of 1, 4, 8, 16 and 32GSM channels. When integrating in a VoIP system, GoIP is highly scalable in meeting customer's requirement on the number of channels (lines). In addition with its power functions, high voice quality, and low price, GoIP is an inevitable choice of many system integrators, call termination operatiors, small companies, and individuals.Key FunctionsGSM Carriers and base Stations OptionalSending SMS / USSD via built-in webpage or SMS ServerRemote SIMAuto balance check and recharge (prepaid SIM)Call time restrictionsRemote Control ManagementRelay Server support for NAT and encryption of IP packetsPPTP VPN and Relay EncryptionBuilt-in SIP Proxy for peer-to-peer operationGSM Quad Band: 850 / 900/1800/1900 MHzCall forward from GSM to VoIP and VoIP to GSMCall BackKey Advantages:Lightweight and PortableEasy to install and administrateIMEI ChangeableGSM base Station OptionalSupport SIM Bank/ SIM SeverManual/ Automatic Selection OperatorsSending and Receiving SMS and USSD (Web Interface)Flexible Dial plan fo number alternation, call screen.Flexible configuration modes.All functions can be set on web.Provide CDR reportFree Software/ServerRemote Control Server----Access Interface Remotely.Relay Server----Relay Encryption( Make Terminals Traversal the NAT without STUN and Outbound Proxy)SMS Server----Remote SIM cards; Send Bulk SMS; Provide CDR and ASR; Auto Balance and Recharge.SIM Server----Remote SIM Cards on Duty; Set GSM Group( Assign several SIMs per GSM Port); Set talk time per SIM, Set Day of week, time range; Monitor CDR, ASR, ACD.Autocfg Server---- Maintence all DBL termial device anywhere; embeded remote control server; Remote sim auto configuration.Protocols: SIP/H.323TCP/IP:IP/TCP/UDP/RTP/RTCP/,CMP/ARP/RARP/SNTP, DHCP/DNSClient,IEEE802.1P/Q.ToS/DiffServ.
