Ditech Networks Brings its Voice Quality Algorithms to Asterisk

Ditech Networks today made its voice quality algorithms are available to the millions of users of the Asterisk Open Source Telephony Project. 

Using VQA’s voice quality monitoring solution, an operator or administrator can pinpoint detailed issues within the voice path, including noise, echo, level mismatches, compression artifacts, packet delay, and jitter. The VQA algorithms can then be applied to manage those artifacts and improve the user experience. In network tests, VQA has been shown to improve average voice quality by up to 0.5 MOS points, which translates into a much improved calling experience.

“The Asterisk PBX platform has had a profound influence on the evolution of the telecommunications industry, and it has facilitated Web/telephony applications that would have been cost-prohibitive if attempted on traditional telephony platforms,” said Chad Madison, who led the VQA for Asterisk initiative at Ditech Networks. “In the spirit of promoting software-based telephony excellence, Ditech Networks has ported its hardware-based voice quality algorithms, and created an easy-to-install software module for Asterisk.”
