similar to: IAX bandwidth optimisation

I have an installation that connects in a [very] good day at 22kbps, but the normal is about 18kbps. I use de ILBC codec, and also change in iax.conf the trunkfreq = 20 to trunkfreq = 30 It works, you can understand well the other person, but don't expect miracles or an outstanding sound quality. > Dear Dan; > > Thanks alot for your kindly reply. > > Well, what u advise us

Well, I don't know how to tune it more, it connects at about that rate in a mediocre rural landline. ILBC uses samples of 30ms, so if you set the trunkfreq set to 20 you will be using more of the necesary scarce bandwidth AND dropping sample info in each frame, thus making audio choppy and unclear. Make shure to disallow all codecs and then allow only ILBC or lpc10 (search for it in

Hi all, We keep getting these and all the calls between these two asterisk boxes get dropped. what is going on here, I have been trying to solve this problem on my own but maybe I don't have the trunk setup right. also I have posed the output of my full log of the machine with the zap interface, the other is using ztdummy. IAX.conf on machine 1: [general] port=5036 ;iaxcompat=yes

I have successfully configured two servers and I am now trying to connect via iax. When I attempt to call from one ext, 2006(server viop1) to extension 3006 (server voip2) I receive a timeout or "call failed 403 forbidden. The information I am receiving from the console is below. Apr 26 10:53:32 WARNING[311313]: channel.c:1745 ast_request: No channel type registered for 'IAX'

I've been looking at some documentation on shared mail accounts. But I'm getting mixed thoughts on how this can or should be done. I use mbox for all my pop and imap folders since I've converted from a uw-imap server. The first thing that makes me wonder about setup is that I've been told to not use maildir and mbox on the same machine, although I'm not really sure why

Hi, I have Gluster 3.2.6 RPM's for Citrix XenServer 6.0. I've installed and mounted exports, but that's where I stopped. My issues are: 1. XenServer mounts the NFS servers SR subdirectory, not the export. Gluster won't do that. -- I can, apparently, mount the gluster export somewhere else, and then 'mount --bind' the subdir to the right place 2. I don't really know

I'm hoping someone can help me out with this. I am basically just trying to separate my outbound and inbound calls into separate contexts instead of having everything in a single context. Any help would be appreciated. Perhaps I've missed something really obvious.... Here is the network layout: <remote> <--TDM400P--> <nattedbox> <--IAX--> <liveipbox>

OS: CentOS 5.0 x86. Hi, I am using CentOS 5.0 at home, ADSL ~16 Mbps/~1 Mbps Internet connection and my ping time to my ISP is 160-170 msec. When downloading something with Firefox, I am getting download speeds of about 100-180 KB/sec (for example when downloading SP2 of XP from MS server). Are the CentOS networking settings OK for this kind of latency, or do I have to change some settings?

hello everyone. Look at the following R idiom: a <- array(1:30,c(3,5,2)) M <- (matrix(1:15,c(3,5)) %% 4) < 2 a[M,] <- 0 Now, I think that "a[M,]" has an unambiguous meaning (to a human). However, the last line doesn't work as desired, but I expected it to...and it recently took me an indecent amount of time to debug an analogous case. Just to be explicit, I would

Hi all, I'm trying to get IAX2 trunking between two * boxes and am having extreme difficulty :) What happens is when the sending * server (the one initiating the call) receives the ACCEPT back from the receiving server it immediately replies with INVAL. I've checked the code and it seems to be not matching the accept packet with the relevant item in the iaxs array due to the following

I'm having a problem with intersite calls over IAX2 being abruptly terminated. Nothing odd shows in any of the logs for Asterisk or the host. The only think I can think it might be is a lag-spike on the site to site connection. How sensitive is IAX2 to lost frames, lag spikes or large variations in jitter with the GSM codec and: bandwidth=low jitterbuffer=no trunkfreq=100 ; Raised from

hello, I have a test setup with 2 asterisk servers, each having a one snom 100 via sip using it. I`m experimenting on how trunking between them would work. I have them setup for RSA authentication which I plan to use in the future. So I`ve setup the keys and servers seem authenticate to each other. One is named phila and other hurricane. Here is what I see on phila: -- Registered

All, I have an issue with IAX that I can't comprehend. Approximately every eight minutes my servers go unreachable. They stay unreachable for exactly 10ms. I have two servers running IAX and it happens on both servers simultaneously. I have searched the archives and see similar issues, but not the exact same one. I am on the current CVS stable version of *. Also, during IAX calls,

Subject: Re: [Asterisk-Users] IAX Bandwidth Question Hi, I have changed the codec to lpc10 (I see what they mean by Mr. Roboto!!) and the ping times generally dont go over 300ms. It seems very odd that GSM saturates the link. I would love to give g.723.1 a try but have no idea where to get the proprietary codec... can anyone help? Thanks Jay > ----- Original Message ----- >

When I'm connected with two clients in the same LAN of the asterisk server using the same codec and the IAX protocol, I have no media passing through the asterisk. But, when these clients are on the Internet, all the media flow pass through the asterisk server. Is that way that it works? I can't see what is the difference. Thank you and I'm so sorry for my poor english. Wendell

So I think that that final result is pretty amazing. That's 35% less bandwidth usage than G.729. Even without the preprocessors help you do 17% better.

Hello everyone, this is my first post to the list, so hello again. We're a small company in Romania and we're trying to set up a really small version of "call center". That is, we want to get a few land-lines from our telco in different countys and "bridge" all calls to our HQ, in order to make it cheeper for our clients to call us. Unfortunatelly there's no ISP

Hi, I am using IAX to communicate between 2 sites, each site is using a 256k/64k ADSL Connection. I have noticed that when I connect my ping time to my 1st hop jumps from 30~ms to over 12,000ms in over a period of about 10 minutes, it just keeps climbing until the link is saturated. Naturally, there is a very long delay when speaking. What bandwidth would be adequate for IAX? or how can I

Hi, I've just joined the list. Thanks Jean-Marc and other contributors for your efforts with Speex. Anyway - I've been hired by a local firm to investigate, write-code-as-required and generally help them get the maximum bang-for-the-byte for VOIP traffic on the hyperexpensive Internet bandwidth going out of South Africa. I started the process by doing some methodical measurements and

Hi all, I'm using VOIPJET to make international calls with an IAX2 connection between my local asterisk server and their server(s). At times I seem to have a problem if 5 or more international calls are made at once - I'm on a 1024kbps download and 256kbps upload DSL line (only the asterisk server uses this DSL line). Today I switched the codec from ulaw to ilbc in an attempt to lower
