Hi I wonder if anyone has any sugestions
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 dahdi_test Opened pseudo dahdi interface, measuring accuracy... 99.997% 99.999% 99.998% 99.997% 99.999% 99.998% 99.998% 99.998% 99.998% 99.998% 99.998% 99.997% 99.998% 99.997% 99.998% 99.998% 99.998% 99.998% 99.998% 99.997% 99.999% 99.998% 99.998% 99.997% 99.998% --- Results after 25 passes --- Best: 99.999 -- Worst: 99.997 -- Average: 99.997895, Difference: 100.002028 but when the CPU is not loaded there is white noise low volume and the results of dahdi_test dahdi_test Opened pseudo dahdi interface, measuring accuracy... 99.992% 99.988% 99.951% 99.991% 99.992% 99.992% 99.992% 99.992% 99.991% 99.991% 99.992% 99.991% 99.991% 99.952% 99.992% 99.992% 99.992% 99.992% 99.951% 99.992% 99.992% 99.992% 99.992% 99.950% 99.991% 99.991% 99.991% 99.992% 99.992% 99.951% 99.992% 99.992% 99.992% 99.991% 99.952% 99.992% 99.992% 99.991% 99.992% 99.951% 99.991% --- Results after 41 passes --- Best: 99.992 -- Worst: 99.950 -- Average: 99.984461, Difference: 100.001168 Could you explain how I can improve the call quality without running the CPU at 99% al the time? running the latest Dahdi 2.4.0 Echo Canceller: OSLEC and asterisk 1.6.2.13 Thanks Robb
