Might want to give PCI latency setting a try, it helped for me. My ZTTEST would drop occasionally to 99.95% until I set: setpci -v -s 01:01.0 latency_timer=ff <--Digium PRI card setpci -v -s 01:04:0 latency_timer=ff <--Digium 401 4 X FXS setpci -v -s XX:XX:X latency_timer=0 <--1 entry for every other PCI card in system from LSPCI output, modify XX:XX accordingly Before setpci I would get best in ZTTEST at 99.987793% and worst ~ 99.95% After setpci best is 100% and worst is 99.987793% consitient. I use SpanDSP to recieve faxes and before faxes were garbled and now they are OK (BTW, now recieving ~150 faxes a day 99.95% OK, so SpanDSP *does* work fine, you just have to set it up right. Ask me how.) I put the setpci statements in /etc/rc.d/rc.local before my modprobes to the Digium hardware and Asterisk startup. I'm using a 4-way Netfinity FC2 * 1.0 stable I dunno, maybe the community is being too hard on Digium about the design of the card. I can understand their perpective, it's brutal to make a card that has to have such tight tolerances and make it work acceptably on the huge variation in white box hardware (or black box, in your case). There's a page on the Wiki about motherboards that work well with installation notes but that's pointless since motherboards are such a moving target. Even the motherboard vendor screwing around with BIOS updates can invalidate that information. Waldo Rubinstein escribió: I was browsing the applications developed in zaptel and came across zttest. |
