We are having trouble with an installation that is getting a lot of echo on some calls. The installation is all SIP phones and they have a VoIP provider. When we call through the voip provider and into another of their customers (voip throughout) there is no echo problem. If we call in their landline, through the TDM400's FXO to one of the SIP phones, there is no echo problem. Sometimes

I have read different posts over the months wondering who Vonage uses for their VoIP technologies. I stumbled across this article (although it's from 2002, I think) that suggests strongly that they use Cisco. There is no telling what they might use in conjunction with this but this should clear some of the conjecture.

Hi All! First, let me introduce myself, as this is my first post to the list (I've been lurking for quite some time now). My name is Matt Hardeman, and I work for a software development firm in Birmingham, AL. We are interested in the Asterisk PBX and it's various configurations first as an internal solution for our occasionally bizarre telephony needs, and eventually are interested

Hi, I can't upgrade an old 7960 from SCCP 3.0 to SIP 7.5. Could you help ? From http://www.cisco.com/en/US/tech/tk652/tk701/technologies_tech_note09186a0080094584.shtml#sccptosip2, I got the following: 1. Copy the desired binary image from Cisco.com to the root directory of the TFTP server. 2. Specify the image in the configuration file image parameter for the protocol

You have the session target as the IP address of the router's own ethernet interface. You probably want that to be the address of the Asterisk server instead. I also highly recommend you use full duplex ethernet, as voice packets don't really like to be restransmitted when a collision happens. -d > Message: 10 > From: "Bartosz Jozwiak" <bartek@cq-link.sr> >

Is there anyone that could explain to me the phenomenon of Echo or at least point me where I can learn more? Why is this affecting the VoIP world so much and not the regular PSTN analog world? What does the PSTN industry have that they can handle such high volume of calls and there is "no" echo problem? Thanks, Daniel

Hi, Can anyone tell me what should be included in h323.conf to get asterisk to talk to a Cisco 2600 gateway? Any statement examples for extensions.conf would also be appreciated. Thanks. Will chan_h323 use the Cisco as a gateway anyway? Regards, Steven Thomas

Everything above 96kbps on that table is speculative, as the highest multi-participant listening testing done was at 96kbps. Here's the results from that test, if you're curious: http://listening-test.coresv.net/results.htm As you can see, at that rate Opus ranged from slightly perceptible to imperceptible. Also importantly, note how few of the donors were able to give significant

Hello, I am having trouble getting counts of values in rows of a data frame. I'm trying to use apply, but it's not working. This gives a sample of the kind of data I'm working with: rating.1 <- factor(sample(1:4, size=10, replace=T), levels=1:4) rating.2 <- factor(sample(1:4, size=10, replace=T), levels=1:4) rating.3 <- factor(sample(1:3, size=10, replace=T), levels=1:4)

hi folks, in my (unlucky) first test of ogg vs other encoders, i found a case where wma and mp3pro sound much better than ogg at 64k. can anyone suggest a setting that i haven't tried yet that can rival the wma and mp3pro samples at 64k? it's the "gravel effect" that is troublesome. the part in question is the first 15 seconds of this wave file:

Hi Jason, Here's rsync10.3xattr_supportv0.6.diff. You can find fileflags.diff and crtimes.diff (that are not from me, but I strongly recommend you to install) here: http://samba.anu.edu.au/ftp/rsync/src/rsync-patches-3.0.5.tar.gz As you could see in the mail from the mail-list, this version have a bug with filenames containing slashes ("/"). They are converted to colons

Here I don't want to start a discussion, but rather share a *solution* that took me some days to come up with. The whole stuff started with a power-outage. After reboot, my server (ext3) came back with the dreaded file system error (Ctrl-D to reboot or password for maintenance) - if you've never seen this, consider yourself lucky! In any case, I did the fsck as prescribed, but abandoned
