A VoIP GSM gateway (GoIP) is an IP-based device that enables inbound and outbound VoIP and GSM cellular calls. It is a great alternative to PSTN, especially in area where GSM service is available for VoIP call termination. GoIP is designed to work in conjunction with key phone systems and IP-PBX to provide GSM communications. The extensive compatibility of the GoIP makes it an ideal choice to be deployed in multi-vendor open architecture VoIP networks. GoIP is a great way to provide fast phone service deployment where regular PSTN line may not be readily available. GSM gateway also provides significant savings in usage, infrastructure and maintenance cost compared to conventional PSTN. | Key Features Provide one (GoIP) or four (GoIP4) cellular channels for IP-PBX Support open standard SIP Protocols (IETF SIP V2) Support SIP proxy mode Multiple GoIPs grouping mode Two 10/100 Ethernet ports for the LAN and an additional device Guad band GSM module: support GSM 850MHz, 900 MHz, 1800 MHz, 1900MHz Speech quality ensured by QoS at LAN, IP layers and comprehensive jitter buffer VLAN and QoS support NAT Transversal Voice prompts, HTTP Web Highly stable embedded Linux operating system in high performance ARM 9 Processor RFC 3892 - SIP Referred-By Mechanism Proprietary Firewall-Pass-Through Technology Codec: G.711 (A/D law), G.729A/B, G.723.1 DTMF: RFC 2833, In-band DTMF, SIP INFO Web-base Management PPP over Ethernet (PPPoE) PPP Authentication Protocol (PAP) Internet Control Message Protocol (ICMP) TFTP Client Hyper Text Transfer Protocol (HTTP) Dynamic Host Configuration Protocol (DHCP) Domain Name System (DNS) User account authentication using MD5 |
Benefits of GoIP Extensive product compatibility with industry leading vendors Cost-Savings on phone calls between mobiles or to PSTN Easy to install - IP device with Web based management interface Can be managed and monitored remotely over Internet - a great service to offer to customers by system integrators GoIPs can be grouped together to establish GSM gateway cluster Termination between GSM/VoIP Schedule or on-demand SMS Broadcast messages to users (additional SMS server is required) 1-year warranty on hardware | Enhanced Features LEDs for Power, Ready, Status, WAN, PC, GSM Call forward from GSM to VoIP and VoIP to GSM Dial in mode or dial out mode only Dial Plan Password protection for both dial in or dial out Retransmit GSM Caller ID to VoIP terminal Dynamic selection of codecs Advanced jitter buffer Automatic traversal of NAT and firewall VLAN / QoS Echo cancellation for Speakerphone Comfort noise generation (CNG) Voice activity detection (VAD) Auto provisioning (requires auto provisioning server) Firmware upgrade from GUI |
