GSM / CDMA / WCDMA to VoIP
Product: VoIP GSM Gateway (Or called as GolP too)
VoIP GSM Gateway / GoIP (GSM over IP): It serves to establish direct connection between GSM network and VoIP.
Sim-card is put into GSM Gateway in order to register it with the GSM network, at the same time the gateway is connected with VoIP. Accordingly the communication (traffic / calls / SMS) can be converted in and out between GSM and VoIP channels.
Background:
Mass-market VoIP services started in 2004, and has been rapidly grew for recent years.
It is becoming increasingly common for telecommunications providers to use VoIP telephony over dedicated and public IP networks to connect switching centers and to interconnect with other telephony network providers.
Because of the bandwidth efficiency and low costs that VoIP technology can provide, businesses are migrating from traditional copper-wire telephone systems to VoIP systems to reduce their monthly phone costs.
And vice versa, many SIP providers who provide VoIP services, to match with customers’ requirements, should connect their VoIP networks to customers’ traditional PSTN network.
How to connect VoIP?
This can be implemented in several ways:
1. VoIP Media Gateway from E1 to SIP, connects PSTN and VoIP by conversion between E1 and SIP.
2. Analog Trunk Gateway from FXO / FXS to SIP, connects PSTN and VoIP by conversion between FXO trunk or FXS extension and SIP.
3. VoIP GSM Gateway from GSM / CDMA / WCDMA to SIP, connects PSTN and VoIP by conversion between GSM / CDMA / WCDMA and SIP.
This file will describe way No 3 only.
Illustrate the solutions of FXO / FXS to SIP
In wireless or mobile network, provides GSM / CDMA / WCDMA interface only.
Vice versa, in VoIP network, provides SIP only.
Because of different interface in both side, connection will be failed.
For example:
Under such a situation, VoIP GSM Gateway / GoIP Gateway comes which makes connection between them.
Or
By using VoIP GSM Gateway / GoIP Gateway from NICEUC, connection between GSM / CDMA / WCDMA and VoIP network is established. After connection is established, for GSM / CDMA / WCDMA users, both of them will get benefit from VoIP technology; for SIP provider, they will easily sell their services and call route to GSM / CDMA / WCDMA users.
