VoIP GSM GoIP 1 Gateway is the VoIP-telephony equipment, designed to connect VoIP-telephony with GSM network via the SIM card installed in the gateway. The GoIP-gateway carries out incoming / outgoing calls through via IP PBX, including the transfer of the user’s Caller ID number from one network to another.
The device is compatible with all standard protocols as follows V4 Standard H.323, SIP V2.0, SIP (IETF SIP V2), SIP proxy mode, IP V6 (TCP / IP), etc. SIP uses two protocols of encryption - RTP (transport) and SIP (dialing, control, and status information). If both subscribers have support for ZRTP encryption, the conversation is carried out via an encrypted channel, if TLS is used, the signaling traffic will be protected.
Exchange channel allocation occurs using the SIP, depending on other protocols used for transmitting information, e.g., RTP. The protocol contains several basic functions and protocols, including RTP, RSVP, SDP, and RTSP. GoIP 1 is also widely used for VoIP traffic termination.
GoAntiFraud offers a comprehensive solution for best GSM termination using GoIP equipment. We cooperate directly with Hybertone manufacturer, so you can buy GSM gateways and SIM GoIP banks at the lowest price. For those who begin doing VoIP termination, we offer NewBusiness solution that includes the required set of equipment, software for automation and tools to protect against the SIM-block.
In addition to SIP, GSM VoIP-Gateway GoIP 1 supports H.323. This is the main protocol that links the functions to transfer data from one equipment to another. H.450.8, H.450.9, H.450.10, etc. operate using H.323. The first one recognizes the subscriber who is called, provides the standard means of data transfer at a point, which is deleted. The second one and the third one to end the call when the subscriber does not get through. H.450.11 interrupts a call between subscribers to avoid overloading the network.
In order to o connect to the Internet, every VoIP GSM Gateway has two ports Ethernet 10/100 MB supporting IEEE 802.3 standard for connection to PCs and LAN equipped with LED status indication.
GSM GoIP 1 basic functions:
- Supports 1 GSM-channel for IP PBX. Redirects phone calls from IP to GSM-network without entering the landline PSTN.
- Operates in the frequencies from 850 to 1900 MHz for GSM and IP.
- Availability of open standards and SIP-protocols (IETF SIP V2). SIP is a type of the protocol for multimedia conferencing as specified in RFC 2543 IETF.
- Availability of SIP proxy mode. Accessibility and the opportunity to dial and call the subscriber.
- Multiple modes of GoIP 1 and grouping. One channel for IP-PBX, with connection and data transfer functions.
GSM GoIP 1 Gateway is the most affordable option of the entire GoIP line-up. Although, the device has only one channel for signal transmission in GSM network, it will cope with the needs of the private business and personal use. Furthermore, this equipment is ideal to master VoIP-telephony and enter the GSM termination market.
