KSV has published web services for integration touch-points with other 3rd party apps like CRM, IVRS and ERP. During the deployment, voice-stream [min 9 Sec string] of users is routed from the IVRS port to the cache of CTI, later to the biometric server. This is an established best practice. Media gateway through the SIP protocol manages all other streams [VOIP] and sends them to the voice biometric server.
