Hi List, I've had some issues with some VoIP providers where either: 1 - There is massive PDD but finally the call goes through 2 - There is massive PDD but the call gets rejected anyways I was wondering if there was a way to automatically detect such behaviors when it happens (maybe with a script or something) so I can take the faulty providers out of the routing and maybe automatically

Hello, I am trying to bootstrap a function that extracts the log-likelihood value and the nls coefficients from an nls object. I want to sample my dataset (pdd) with replacement and for each sampled dataset, I want to run nls and output the nls coefficients and the log-likelihood value. Code: x<-c(1,2,3,4,5,6,7,8,9,10) y<-c(10,11,12,15,19,23,26,28,28,30) pdd<-data.frame(x,y)

Has anybody experienced problems with a DSL modem stopping all other traffic when an IAX channel opens up? I've really traced this thing out as best I can - it isn't a lack of bandwidth on the DSL connection (I've had three concurrent Ulaw calls coming in at once with no problems), nor a problem within the network (other intranetwork traffic isn't affected by the call) - the

Hi, I have one satellite link and one sdsl link. And, one LAN link. My load balancing is working great with a iptables''s masquerading (no fw rules). Now, I need to route the following ports to my sdsl link: - 20, 21, 22, 25, 80, 110, 143, and 443 Whereas the others go to my satellite link. Does anyone done this before?

Hello, Would like to use IAX /IAX2 to transport 30 channels inter Asterisk. I don't have any experience with that, so can someone help ?? How much bw do I need for simultaneous calls and is there any latency for SIP G711 to IAX2 and vice-versa , ... etc ? Thanks in advance for any info, Geo ___________________________________________________________________________

Grasping at straws here...is anyone using a Dell PowerConnect 2224 24-port unmanaged 10/100 switch in a deployment? I have two separate asterisk installations with bad one-way audio where the only common elements left are the Dell switches and Polycom IP-500 phones. Two different ITSPs - one location uses IAX2 to the outside world, the other SIP. Two different bandwidth providers, one SDSL 1.5

Would anybody have any numbers on how large a box would be required to convert 100 or 200 SIP calls to IAX2, without transcoding, echo cancel, .. Or a setup with individual IAX2 calls coming on one side, and trunking being used to 1 or more remote boxes on the other side, to improve bandwidth usage ? It doesn't matter if you don't have a test done for exactly 100 or 200 calls, I'm

Hi, I've had an inquiry for a small UK call centre, mostly outbound calls. I get the impression they are mainly calling 3G mobile phones, monthly phone bill, with calls is approx ?5,000 for several feature lines. How feasible is something like this with asterisk? I guess one big question is which type of circuit to use, ADSL in the UK is only 256kbs upstream, some providers do bonding but

Hi again, I keep posting about my problem with HTB -> http://mailman.ds9a.nl/pipermail/lartc/2005q3/016611.html With a bit of search I recently found the exact same problem I have in the 2004 archives with some graphs that explain it far better than I did -> http://mailman.ds9a.nl/pipermail/lartc/2004q4/014519.html and http://mailman.ds9a.nl/pipermail/lartc/2004q4/014568.html

I've been having 'gappy' audio problems with nufone for about a week now but I think I've nailed it down. Setup: office* - iax2 - colo* - iax2 - nufone office* and colo* are identical physical hardware (Xeon 2.8, dual ethernet, solely used for Asterisk) -- they are joined together through their second ethernet ports over a dedicated 2meg SDSL link. One hop between office* and

I am curious if anyone has had problems trunking iax2 with 100+ concurrent calls. I am planning on testing this out tomorrow, however I wanted to know if anyone else has had a problem with this prior to my test so I know what to look for if anything is known and what resolutions have been found if there are any known problems. Specifically I am doing this on fbsd 6 with asterisk 1.2.4 using

Hi folks, At work, we're considering the idea to replace the presente router with a stardard box with CentOS as a SO and GNU Zebra as a routing software. The line is a 4Mbps SDSL. ?What do you think about Zebra and what are your experiencies with it? Any feedback will be so appreciated. TIA.

Hi, This question is both technical and business related. I've got a prospective customer in France which belongs to Hotel industry. He has a lot of visitors coming from the Nederlands. I'm studying the opportunity to offer phone services to those visitors. The service I'm thinking about is plain local call termination : hotel guests cost effectively call their relatives in their

Hi all, Our company has deployed a Mitel 3300 system (only about 2.5 years ago) and we are experimenting with setting up Asterisk in our head office (for business continuity, ie we have a bird flu epidemic and no-one can come in, therefore use SIP softphones at home to co-ordinate activity) and at a remote site in the Isle of Man (connected via 2Mbps SDSL) Ideally we'd like anyone on either

My desktop environment has become a little chaotic, and, long story short, I would like to uninstall KDE and Gnome, and then reinstall Gnome. (I want to remove KDE for the time being because I just don't think I want it taking up space on my hard drive). The thing is, I don't want to throw the baby out with the bathwater. For instance, I want to make sure I don't lose settings in

Just in case anyone else hits this. I just installed R 11.0 alongside R 10.1.0 (off my D: drive in D:\R\... but I think that's irrelevent) and all went well, I selected my nearest CRAN mirror (Bristol is the one I like) and getting the selection list seemed to take ages though it did come eventually. However, I then got an error message saying that R couldn't make contact on port 80. I

After playing with the vorbis code for a while and doing tons of hacks and analysis on it, I've found it to perform very poorly with impulse signals. The MDCT seems to cause lots of spreading, and it seems to result in much worse impulse performance then mp3. What is the current plan on handling this? Will a smart quantizer be able to avoid it? I've been looking at various ways of
