similar to: RTA, jitter, MOS et al over the internet

Does anyone out there have a recommendation for tools that will monitor the quality of VoIP systems? I am looking for jitter and MOS monitoring. I have a custom Nagios plugin that is alerting me if the jitter jumps out of a 20ms but I am looking for a little more detail. I would not be against writing something in Perl for Nagios to do but I don't really know where to start on measuring jitter

Hi, I've upgraded the driver provided by the manufacturer of the C-MOS [1] UPS, which is an argentinian company. The file I'm attaching works with nut 2.0.4, I have one C-MOS UPS and I've succesfully tested it. It would be nice to have it included in the nut codebase.

Hello All, MOS and R factor are the two QoS parameters used to estimate VoIP call quality. I have found that they are calculated from other metrics like jitter, latency, packet loss,...etc. But, haven't found any formula or arithmetic rule to calculate them. Do you have an idea about their formulas or an open source that calculates them. Is it possible to interpret them from wireshark.

Hello all, I'm tring to retrieve a formula to calculate a MOS value from Asterisk RTCP stats... Have you got any idea how to do it? Thanks I'm reading all G.107 ITU docs to retrieve something... I'm saving the SIP RTCP stats with: [macro-hangupcall] exten => s,1,Set(CDR(userfield)=${CHANNEL(rtpqos|audio|all)}) exten => s,n,ResetCDR(vw) exten => s,n,NoCDR() So I retrieve

Hi, Although this is a repost from Asterisk biz, we would like to ask if somebody may help us to develop a native Asterisk module using AQuA technology for voice quality monitoring using the same web service AQuA Meter is using.

Is there any tool that can do LCR for Asterisk but also take into account MOS scores? Is it possible to automatically generate MOS scores on random "calls" so as to keep an updated database on a per provider, per destination, per time-of-day score? Hopefully, with that information we can create a better LCR module or script? Thanks, Daniel

Dear all, I am using MOStest in vegan to examine the hump-shaped of a quadratic regression model. In the manual of vegan, it mentions that the value of MOStest include isHump. My result showed the quadratic regression is hump-shaped according to the p-value (nearly 0). However, the value isHump did not show up. Please kindly help where to find isHump. Further, I do not understand the result of

OK. Different mailing lists are set up differently. This list is unusual because your answers only go to the person who replied to you. So if you want the other people on the listserv to see your answer, you should make sure that Speex-dev at xiph.org<mailto:Speex-dev at xiph.org> is added to the TO: field of your outgoing message.

Hello, I just signed up to this mailing-list (note: my first mailing list at all), because I'm having some problems related to speex. Let me just introduce you to what I'm doing. I am writing a short (really short) paper about VoIP techniques, especially audio codecs for speech. I pointed out basic technologies behind audio codecs; vector quantization, lpc, long-term prediction and some

Dear all, I am studying a dataset using the aov() function.

ZFS documentation lists snapshot limits on any single file system in a pool at 2**48 snaps, and that seems to logically imply that a snap on a file system does not require an update to the pool?s currently active uberblock. That is to say, that if we take a snapshot of a file system in a pool, and then make any changes to that file system, the copy on write behavior induced by the changes will

Hi all, Suppose I have a PurchaseItem model which refers to Product model... class Product < ActiveRecord::Base has_many :purchase_items end class PurchaseItem < ActiveRecord::Base belongs_to :product end To keep things simple, one of the attribute of the Product model is title. On the interface, I have a textfield that I need to bind with @purchase_item.product.title.

I''m going to submit a patch that will call wxInitializeStockObjects wxInitializeStockLists wxInitAllImageHandlers in wx.cpp on startup. I''ll remove the calls from all the samples. Does anyone have any beef with this? Roy

it seems that --enable-utmpx and friends have the effect of disabling the corresponding feature (i.e., #define-ing DISABLE_UTMPX etc.), which leads to the (perhaps not so) obvious breakage of UseLogin on Solaris etc. For the less anal (or reformed anal) configure-r who leaves these unspecified, everything is OK i'd suggest changes to configure.in, but i'm blissfully ignorant of autoconf.

Does anyone know what is the difference between all the memory objects? I've encountered 0x003d, 0x003e, 0x0040, 0x0041, and even 0x0070 (on G80). According to renouveau.xml these are NV01_MEMORY_LOCAL_BANKED, NV01_MAPPING_SYSTEM, and so on. But what do they actually do? What separates one kind of memory from the other?

Hi everyone, I'm looking to move terminus.zytor.com, the server that hosts among many other things http://syslinux.zytor.com/ somewhere else on fairly short notice. Unfortunately my home network connection is a cable modem with dynamic IP and a "no servers" (sigh) policy, so that won't quite work. If you happen to have available or know of a place in the San Jose,

Hi Thomas, it sounds like all the changes you need are to clang, and nothing in LLVM proper needs to be changed. Is that right? Ciao, Duncan.

I am loving Asterisk! I have a Cisco 7960 (Sip) on which I want to try using g729 encoding. I cannot find a setting for this in the phone's interactive screen menu. Do I set it in the sip.conf file? I have also ordered 2 licenses from Digium. My understanding is that because this Cisco phone can handle the encoding, * just passes it thru. Is this correct? Also, I am using LiveVoip for
