[asterisk-users] TDM400P periodic sound clicks on FXS
Hi, I am having periodic sound clicks (2-3 per second) on all FXS of a TDM400P when the remote end is my VoIP provider. However: - recording the conversation on the asterisk, does not have the glitches, although I can hear them on a real phone. - My VoIP provider to my VoIP phones through the same asterisk is OK. - TDM to TDM through the same asterisk is OK. I tried with and without echocancel and different values of echotrain (including 'no'), without luck. The card is not sharing interrupts. Any ideas? Kernel is 2.6.9 asterisk is 1.2.19-BRIstuffed-0.3.0-PRE-1y-h # lspci 00:00.0 Host bridge: Intel Corporation 82945G/GZ/P/PL Memory Controller Hub (rev 02) 00:02.0 VGA compatible controller: Intel Corporation 82945G/GZ Integrated Graphics Controller (rev 02) 00:1e.0 PCI bridge: Intel Corporation 82801 PCI Bridge (rev e1) 00:1f.0 ISA bridge: Intel Corporation 82801GB/GR (ICH7 Family) LPC Interface Bridge (rev 01) 00:1f.1 IDE interface: Intel Corporation 82801G (ICH7 Family) IDE Controller (rev 01) 00:1f.2 IDE interface: Intel Corporation 82801GB/GR/GH (ICH7 Family) SATA IDE Controller (rev 01) 00:1f.3 SMBus: Intel Corporation 82801G (ICH7 Family) SMBus Controller (rev 01) 01:00.0 ISDN controller: Cologne Chip Designs GmbH ISDN network Controller [HFC-4S] (rev 01) 01:02.0 Network controller: Tiger Jet Network Inc.

This is just shooting off of my hip, but maybe a jitterbuffer issue, like with the phones? I think when Asterisk bridges SIP->SIP calls, it doesn't do any jitter buffering.
