Asterisk Software Add-On

Echo Cancellation

For Asterisk users that connect to the PSTN, the most common type of echo is hybrid echo - the echo introduced by the impedance mismatch between 2-wire and 4-wire telephone circuits. The echo manifests as a distorted and delayed reflection of the users voice while in conversation with an external party through the PSTN.

Host-based Toll-Quality echo cancellation software is designed to operate under 32-bit and 64-bit Linux and provides echo cancellation for configurable tail lengths of 16ms (128 taps), 32ms (256 taps), 64ms (512 taps), and 128ms (1024 taps).

IVR Voice Prompt

The growing installed base of Asterisk® open source PBX/IVR software has created the need for custom IVR prompts which mesh with the existing prompts in Asterisk. This not only minimizes your need for recording additional prompts, but makes customization seamless to the user.
