Hi <br><br>I wonder if anyone has any sugestions<br><br><br>I have had a TDM400 for a couple of years, and I have always
had problems with noise on the line, so tonight I have been doing some
research and have found that if I load the CPU dahdi_test has almost
perfect results and no noise<br>
<br>dahdi_test<br>Opened pseudo dahdi interface, measuring accuracy...<br>99.997% 99.999% 99.998% 99.997% 99.999% 99.998% 99.998% 99.998%<br>99.998% 99.998% 99.998% 99.997% 99.998% 99.997% 99.998% 99.998%<br>99.998% 99.998% 99.998% 99.997% 99.999% 99.998% 99.998% 99.997%<br>
99.998%<br>--- Results after 25 passes ---<br>Best: 99.999 -- Worst: 99.997 -- Average: 99.997895, Difference: 100.002028<br><br><br><br>but when the CPU is not loaded there is white noise low volume and the results of dahdi_test<br>
<br>dahdi_test<br>Opened pseudo dahdi interface, measuring accuracy...<br>99.992% 99.988% 99.951% 99.991% 99.992% 99.992% 99.992% 99.992%<br>99.991% 99.991% 99.992% 99.991% 99.991% 99.952% 99.992% 99.992%<br>99.992% 99.992% 99.951% 99.992% 99.992% 99.992% 99.992% 99.950%<br>
99.991% 99.991% 99.991% 99.992% 99.992% 99.951% 99.992% 99.992%<br>99.992% 99.991% 99.952% 99.992% 99.992% 99.991% 99.992% 99.951%<br>99.991%<br>--- Results after 41 passes ---<br>Best: 99.992 -- Worst: 99.950 -- Average: 99.984461, Difference: 100.001168<br>
<br><br>Could you explain how I can improve the call quality without running the CPU at 99% al the time?<br><br>running the latest Dahdi 2.4.0 Echo Canceller: OSLEC and asterisk 1.6.2.13<br><br>Thanks <br><br>Robb<div style="visibility: hidden; display: inline;" id="avg_ls_inline_popup">
