C H A P T E R 7 Cisco TSP Media Driver Cisco Media Driver introduces a new and innovative way for TAPI-based applications to provide media interaction such as play announcements, record calls, and so on. Cisco TSP 8.0(1) includes support for both Cisco Media Driver and Cisco Wave Driver, but only one driver can be active at any given time. From Release 11.5(1) onwards, Cisco Media Driver is deprecated. Important Cisco Media Driver offers several advantages: • Simplified Installation and Management—Cisco Media Driver configuration can be completed through the Cisco TSP Installation Wizard. Channel and port settings are consistently and automatically applied to all configured TSP instances. • Performance and Scalability—Cisco Media Driver can scale to support up to 1000 configured ports with hundreds of simultaneously active media channels. Refer to the application vendor's Installation Guide to determine the number of channels supported by the TAPI application. • Codec Support—Cisco Media Driver supports 8KHz, 16-bit PCM, G.711 a-law, G.711 u-law natively. Additionally, G.729a can be supported when pass-through mode is enabled. • Reliability—Cisco Media Driver runs as an independent process, similar to Windows applications, providing greater application stability and reliability. Creating and debugging media applications is now much easier. • Cisco Rtp Library Components, on page 422 • TAPI Application Support, on page 423 • EpAPI Functions, on page 426 • EpApi Error Codes, on page 441 • Callback Function, on page 442 • Data Structures, on page 443 • Trace Options, on page 445 • Known Problems or Limitations, on page 446 Cisco Unified TAPI Developers Guide for Cisco Unified Communications Manager, Release 15 and SUs 421
