Build Your Own Call Centre Using Asterisk and Vonage SIP Trunking

A minimalist call centre setup is described using Asterisk as the IP-PBX system and SIP Trunking for VoIP communications. The setup requires an Asterisk server installed on a Linux server, a Vonage API account with an API key and Direct Inward Dialling (DID) number, and softphone software configured to connect to the Asterisk server. The setup allows incoming calls to be forwarded to agents using extensions and provides a basic framework for expanding features such as call recording, IVR systems, monitoring, and reporting.
