OFS-GP16

GP is designed to work in conjunction with key phone systems and IP-PBX to provide GSM communications. The extensive compatibility of the GP makes it an ideal choice to

be deployed in multi vendor open architecture VoIP networks. GP 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.

Benefits of GP

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
GPs 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

Key Features

Provide one (GP) or four (GP4) cellular channels for IP-PBX
Support open standard SIP Protocols (IETF SIP V2)

Descreiption

A VoIP GSM gateway (GP) 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. A typical set up is

shown as follow:

User account authentication using MD5

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
VLAN / QoS
Echo cancellation for Speakerphone
Comfort noise generation (CNG)
Voice activity detection (VAD)
Auto provisioning (requires auto provisioning server)
Firmware upgrade from GUI
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
