Integrating GSM VoIP Gateway with SIP Softswitch

A SIP Soft switch, also known as an IP PBX, integrates with a VoIP gateway, such as a GSM VoIP Gateway, to allow the conversion of voice signals from the telephone to packets of data for transmission over data networks. VoIP service is the transmission of voice over the Internet. It is very effective for places with low bandwidth connections. When you use VoIP service, you don’t need to carry a heavy phone with you.

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
  • IP v4, UDP/TCP, PPPoE, DHCP, FTP / TFTP ARP, RARP, NTP
