Dialogic has announced that it will offer active support for its line of Dialogic Diva Media Processing boards for the Asterisk Environment. If used in an Asterisk system, chan_dialogicdiva can take advantage of the DSPs and rich media processing and signaling power of the Diva board to offload a number of functions that are usually handled by the CPU of the Asterisk Server. This can reduce the load on the CPU and benefit the performance, reliability and scalability of the Asterisk system. The functions that are handled by the Diva board include DTMF recognition and Generation, PULSE detection, Tone detection and Generation, Faxing, Echo Cancellation, and Multi-Party Conferencing. In addition the Diva boards can conference up to 120 active callers without causing load on the CPU.

Some of the media features of Diva boards are echo cancellation (up to 256ms), DTMF detection and clamping and modem or fax support. Some of their signaling features are worldwide support of protocols and services, including Q-SIG flavors and SS7 (ITU-T). Dialogic's support and global distribution networks are prepared for more Asterisk/Open Source solutions working their way into channel distribution networks. The availability of Dialogic hardware for Asterisk/Open Source projects will also allow developers to distribute their products on the task-specific hardware that has set standards for reliability and support.
