I. 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. 


II. 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.
