Notes:
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.
