wholesale and retail 4 channels gsm voip gateway, goip 4 voip gateway

Description:

The GoIP series gateway is a broadband relay gateway newly developed by DBL Technology. It is a new product for seamless connection between the GSM network and VoIP network. When the mobile phone SIM card is installed in the GoIP, users can register the GSM phone to the VoIP softswitch system. Through the GoIP, users can realize the uplink and downlink calls between the GSM network and the VoIP network. In addition, the GoIP supports the transparent transmission of the caller number from the PSTN to the VoIP.

GoIP is designed to work in conjunction with key phone systems and IP-PBX to provide GSM communications. The extensive compatibility of the GoIP makes it an ideal choice to be deployed in multi-vendor open architecture VoIP networks. GoIP 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.

The GoIP features embedded SIP and H.323 protocols with flexible setting. The bi-directional password authentication (call authorization) and trust list authentication greatly minimize the risk of charge losses and the flexible routing function can meet special requirements of various call forwarding. In particular, the GoIP gateway supports multi device groups, with flexible setting of large GSM gateway groups with different channel numbers. With its low price, excellent voice quality, and powerful features, the GoIP series gateway is the first choice for system integrators, traffic operators, and softswitch manufacturers.

Inbound Call Centre for Customer Service 
1.Inbound call centre is operated by a company to administer incoming product support or information inquiries from consumers.
2.This application requires customers to call in via a single phone number. Each GSM channel in a GoIP has its own phone number. In order to achieve calling in via a single number, GoIPs must be configured in a phone group mode with one GoIP as a host and the others as clients. 
3.An incoming call to the host GoIP is automatically forwarded to an idle GSM channel in the phone group. The call is then routed to a call attendant via a VoIP connection.
4.Key advantages: quick setup, scalable, portable, low system cost, low operating cost especially used in cellular network no charge on incoming calls. 

Outbound Call Centre for Telemarketing / Solicitation 

1.Outbound call centers are normally operated for telemarketing, solicitation of charitable or political donations, and debt collection etc.
2.In this application, only outgoing calls are made. GoIPs could be configured as SIP clients to registering to the SIP server / IP PBX or as a SIP Trunk to accept calls routed from the SIP Server / IP PBX.
3.Key advantages: quick setup, portable, scalable, low system cost, low operating cost.
