Introduction[edit | edit source]

CSTA stands for Computer Supported Telecommunications Applications. It is an abstraction layer for telecommunications applications.
VTX operates a CSTA Gateway following the CSTA III Standard which means, that if a customer operates a CSTA compatible CRM and a VTX VirtualPBX (vPBX), customer CRM can control the vPBX remotly (standard features as Make Call, Answer, Clear Connections and more).
