Re: [asterisk-users] trixbox, sangoma a200, dell poweredge 2550 issue
Thanks, Steven. Do both parties hear the crackling, etc? No, just the users in the Office, and its like a background crackle that happens with voice and silence. This happens all the time, every call. Called the Office number from VoIP phone to VoIP phone and the quality is terrible. Don't have any other lines to test in the office. Not contacted Sangoma yet. Thought I would take a look round here first Thanks, PaulG.

Do you have a spare machine you can try instead of the Dell? Even a workstation? Thanks, Steve Totaro On Tue, May 20, 2008 at 5:21 AM, Paul Goodyear [EMAIL PROTECTED] wrote: Thanks, Steven.

Re: [asterisk-users] trixbox, sangoma a200, dell poweredge
Is there any reason why I should be experiencing such bad line quality on inbound calls from PSTN? Call quality is perfect when plugging in a regular analogue phone. Do you have other phone lines you can try the A200 with? Have you asked Sangoma support? Ditto on Sangoma support - they are excellent. Do you have hardware echo cancellation on this board? (Is there a D at the end of the model number?). Sangoma's hw echo cancellation is outstanding, if you are hearing training then I assume you aren't using it or the board doesn't have it. Assuming the PC is doing other only nominal things, yes, this PC is capable for what you are doing. (PC is NOT the VPN endpoint, don't have Tomcat, SQL or a spam filtering on a mailserver running on this box, etc.). Check that you are using IO-APIC and that everybody is getting their own interrupts. Do ifconfig w1g1. w1g1 Link encap:Point-to-Point Protocol UP POINTOPOINT RUNNING NOARP MTU:8 Metric:1 RX packets:1243390644 errors:0 dropped:0 overruns:0 frame:0 TX packets:1243390644 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:100 RX bytes:9947125152 (9.2 GiB) TX bytes:9947125152 (9.2 GiB) Interrupt:233 Memory:c206-61fff Check that errors/dropped/overruns are low if not 0. If they are not 0, re-run ifconfig and check that the numbers don't increase (they can have errors when the drivers first load and get synced up, but then stabalize. Be concerned if the number is not 0 and is over 1000. Based on your description of 2 fxo 1 fxs board, I think you actually have an A400 (as the A200 only accepts 2 modules total however it may still be reported as an A200 family - don't know, haven't used a 400 yet). Do wanrouter hwprobe to find out your info - note HWEC=32 means HW echo caneller, IRQ=233 (higher than 16) means you have IO-APIC activated. --- | Wanpipe Hardware Probe Info | --- 1 . AFT-A200-SH : SLOT=2 : BUS=5 : IRQ=233 : CPU=A : PORT=PRI : HWEC=32 : V=11 Card Cnt: S508=0 S514X=0 S518=0 A101-2=0 A104=0 A300=0 A200=1 A108=0 Armed with more info, Sangoma support (or us on the list) can help out more. dbc. ___ -- Bandwidth and Colocation Provided by http://www.api-digital.com -- asterisk-users mailing list To UNSUBSCRIBE or update options visit: http://lists.digium.com/mailman/listinfo/asterisk-users
[asterisk-users] trixbox, sangoma a200, dell poweredge 2550 issue
Hi all, I have setup a Dell PowerEdge 2550 with a Sangoma A200 card with 2xFSO and 1XFS modules. The PowerEdge specs are 1 x P3 1133MHz, 512MB RAM. Sangoma A200 has 3 analogue PSTN lines connected. This server is based in Office 1, with 5 users all with a Linksys SPA942 VoIP Handset. There is another Office (Office 2) connected to here using VPN. There are two users in Office 2 with the Linksys SPA942 VoIP Handsets, they are connected also over VPN to the remote Trixbox. When placing calls from either Office 1 or Office 2 calls are fine, there is echo to start with (Echo training) but then it clears. Volume is ok, quality is ok. However when an incoming call is made to the office the quality is pretty bad, crackles, low volume. There has also been mention (In office 1) of some cross talk. The Trixbox is plugged into the master switch in the server room, where the various production servers are running, and all workstations are also connected directly to the switch. Is there any reason why I should be experiencing such bad line quality on inbound calls from PSTN? Call quality is perfect when plugging in a regular analogue phone. I am in the process of having all the VoIP handsets in Office 1 connected directly to its own switch, and then connected to the Trixbox directly to avoid server/workstation bandwidth issues, but I don't think would solve the quality issues. Is the PowerEdge powerful enough to handle the VoIP traffic. I am really at an end with this, and really need to find a solution. Any help, advice or pointers would be greatly welcomed.
