...we use exclusively Digium B410p cards that provide 64ms tail EC. For several reasons we'd like to switch to external BRI gateways like the Patton smartnodes (the price is getting really close to a B410p). I'm however curious about their HW EC. I see in the datasheets that it only has 25ms tail per channel (pri are 128ms, but not BRI). Are some of you using these gateway and do your experience (many) echo problems on calls ? Our other alternative is to use sangoma cards that have 128ms HW EC and seem more stable overall, but it is yet a bit more expensive. Thanks for your feed...

Hello, I am trying to get the TC command to work on our debian box to limit traffic in and out to 12 Meg. The command I am using is: tc qdisc add dev eth0 root tbf rate 12000kbit latency 25ms burst 1600 tc qdisc add dev eth1 root tbf rate 12000kbit latency 25ms burst 1600 The problem I am having is that the bandwidth exceeds the 12 Meg by almost 5 Meg. Any help is appreciated. Thanks Mike Pearson

Hello, I have found that the use of sort_by_value very slow. 16800 result, return to the previous 10, sorting takes about 25ms. And if you do not sort, returns 10, need only about 0.3ms. How to make the sort faster? -------------- next part -------------- An HTML attachment was scrubbed...

hi all, long time since i posted on the list. just wondering if anybody has played around with hfsc and if so could he/she share their info on it thanks adrian -- To mess up a Linux box, you need to work at it; to mess up your Windows box, you just need to work on it. _______________________________________________ LARTC mailing list / LARTC@mailman.ds9a.nl

...s a local mp3 file) did read enough byte[] from the file (buffer=20KB) and send them to his bus, he waits the difference in time he has until 1 sec is full. Thus effectivly sending 20 KByte/s. So far this results in the producer to sleep for ~975 ms (transportaion of byte[] through bus taking ~25ms), thus I have an Idle thread running around. The ~25ms per producer would allow me to serve 40 producers (1000ms/25ms) with one server. This number seemed to be far too low, so I thought about a way to increase idle time for the producers. I came up with this idea and would like to know what yo...

...b68.shtml It will tell you just about everything you wanted to know about echo and more :) The short answer to your question, however, is that echo is comprised of two components: volume and delay. Increase either one and the problem gets worse. In the PSTN, the delay tends to be rather short (25ms or less) for most calls, and therefore, tends not to be noticed by the average listener. In a VoIP call, on the other hand, you must first translate the audio signal into digital, with a subsequent delay, pass the digital data through various routers, each of which add additional delay, then...

...P to an asterisk box in a datacentre using g729. The asterisk box in the datacentre connects to our other asterisk boxes providing pstn connectivity via IAX2. Latency between these boxes is between 1 and 2ms. The ADSL connections to the client sites are all consistently delivering latencies of sub-25ms to the datacentre and there is traffic shaping on that connection to give priority to any traffic from the phones' IPs. Comments from the users at these sites are as follows: "call sounded like a dalek and I couldn't make out anything the caller was saying" "the phone on my...

Hello I purchased an AEX800 card to replace the ageing cheap channel bank/T1 card solution a few months ago, assuming that it would be a more robust solution for my small scale phone system. However, it appears to be anything but that. Originally implemented as a XEN dom-u virtual machine on a large server class machine, using PCI passthrough to pass the AEX800 and a small older TDM400, then

...ul if ntlm_auth returns 0. Since I had error messages in the logs pointing to requests timing out on ntlm_auth I wrote a short C wrapper around ntlm_auth to log the time it takes to return (as well as the username and domain). That showed that while most (~90%) authentications succeed in less than 25ms, about 10% take longer than 100ms with some taking as much as a few seconds (2-4s). So I increased winbind max domain connections on the (linux) server while also raising the MaxConcurrentApi on the DC. I now see 39 connections open to the DC from winbind (that number fluctuates). And yet the pro...

Some examples for 2 MiB BDP: - 200ms @ 84 mbps - 100ms @ 168 mbps - 50ms @ 336 mbps - 25ms @ 671 mbps - 12ms @ 1398 mbps - 6ms @ 2796 mbps - 3ms @ 5592 mbps Not everyone runs networks which exceed these parameters, but we do on high-latency WANs. The problem I'm seeing is the artificial bandwidth restriction resulting from CHAN_TCP_WINDOW_DEFAULT being supplied to channel_new...
