Hello all, I am facing as serious problem when running asterisk in HP server.We are developing application to make the outbound calls in PRI lines .We normally uses IBM machine as our servers ,and it was working fine for all installation.For the cost reduction we this time tried with HP server. Model(HP proliant ml110). When we make the calls the there is a lots of disturbance in the sound even if we make a single calls the issue persist .I found in google that these issue normally comes by the load or by the line or by the IRQ . As in my case i am making a single call the 1 st case wont occur here.Also i tested it with one smoothly working E1 to the same card and still the problem came.so I guess the problem is with IRQ. But when i tried it with a normal PC with pendium 4 processor it was working fine. My question is whether the Digium card had any hardware compatibility issue with HP proliant ml110 server.Why the sound has issue in HP server when it working fine in a normal pC with pendium processor...?? When i switched to Asterisk now it is very much ok. can any body explain why it have when using with ubuntu........??? -------------- next part -------------- An HTML attachment was scrubbed...

It does not relate to the penTium processor, or the general spec of the machine. The amount of memory/processor wont change this. Its a pretty intrinsic feature of the motherboard. Some allow you to change this, others you have to change slots. Others you have to disable onboard hardware and hope for the best. On a 110 we couldn't get much use out of it. Only one (two?) PCI slots and both shared IRQs with stuff.> When i switched to Asterisk now it is very much ok. can any body > explain why it have when using with ubuntu........???Wha? Steve

It might be something very simple causing the problem (like X running or something like that) which is making the system's interrupt latency increase to something at an unreasonable level for Zaptel to operate properly. In any case, it's possible that it's a very quick problem to fix and that technical support will be able to help you with. Also, make sure before you try calling to verify that it's not an OpenVox card. I have had customers who thought they were sold a Digium card, but were in fact sold an OpenVox card which did not perform as well as would be expected from our cards, causing some grief and confusion for them. It can be confusing because they use the Digium driver and look like a Digium card to the driver. --- Matthew Fredrickson Digium, Inc.

That said, we are running 2 servers with 4xPRI Digium cards on IRQ's shared with ethernet cards, and the problems almost went away about a year ago with a Zaptel (now DAHDI) upgrade. We still lose networking on one of the servers about once every three months due to IRQ problems, but that is with the oldest PRI card. If our PRI's weren't going away (turning into SIP) I'd probably replace the card with something newer. Possibly Sangoma, but I'm confident that current Digium cards are fine too. All in all, I don't think your problems are IRQ-related. I'd suspect power saving actually; try making the CPU run at a fixed frequency. If that helps, a recent-ish kernel is likely to handle variable CPU frequencies better. /Benny
