GSM VoIP Gateway

What Is GSM VoIP Gateway

Smoothly transit between mobile and VoIP network

GSM/CDMA VoIP Gateway is a multi-functional product used to effectively implement the smooth transition between mobile and VoIP network. It has great improvement not only in software features but also in new hardware structure design. It is fully compatible solution to your need and easy to use. Moreover, with built-in 4–1 antenna power divider which is saving space and more easier to install and maintain. The Dinstar UC2000 series VoIP GSM/3G/4G Gateways offer complete choices scalable from 1 to 32 channels, implement the state-of-the-art functionality in market as always, and enable the smooth transit between mobile and VoIP networks. Integrated GSM/WCDMA/LTE connectivity and SIP protocol compatible with mainstream VoIP platforms, it is suitable for enterprises, multi-site organizations, call terminators and areas with limited landline like rural area to cut down telephony costs and enable easy & efficient communications. GSM Gateways are perfect for redundancy, T1 outages, or as a connection in places where inexpensive analog or SIP connections are not available. They are ideal for remote locations where you have cellular connection but no Internet. If need be, with a GSM Gateway you can create and run you entire remote phone system off of back up power and a cell tower. For added assurance, you can add on a Go3 No Questions Asked replacement warranty!

Network Protocol

Network Protocol

A network protocol is a set of established rules that dictate how to format, transmit and receive data so that computer network devices -- from servers and routers to endpoints -- can communicate, regardless of the differences in their underlying infrastructures, designs or standards. To successfully send and receive information, devices on both sides of a communication exchange must accept and follow protocol conventions. In networking, support for protocols can be built into software, hardware or both.
