For Voice Over Internet (VoIP) Telephony capability using Session Initiation Protocol (SIP), Blueworx Voice Response for AIX runs on different models of NEBS compliant BladeCenter computers without the need for a Digital Trunk Ethernet Adapter (DTEA) card. All Power BladeCenter systems are supported for VoIP/SIP, including: BladeCenter JS20, JS21, JS23, and JS43.
The VoIP/SIP support is implemented by a software simulation of a DTEA card named Digital Trunk No Adapter (DTNA), which allows most Blueworx Voice Response for AIX applications to run without the need for a DTTA, or DTEA adapter.
For information about Voice over IP and how it is implemented in Blueworx Voice Response Version 6.1, see Voice over IP.
