Calling 7777 from a local extension on my local network, I get good voice quality from asterisk, and asterisk reliably recognizes my dtmf input. I set up a sipphone trunk (free) and called in to it via a separate sipphone account on another computer, and got slightly lower, but still good, audio quality. I set up a FWD trunk (free) and called in from the other computer, and got somewhat lower

hi group , i am working on dahdi_monitor for measuring voice quality , so i want to know that on which data i can tell that this PRI lines are working properly, is there any measurement on basis of that i can make MOS. i am working from last 2-3 days but i only get idea about making .raw file and making .wav file and visulal mode of RX and TX of PRI line. what i want is measurement of voice

Hello all, We have a slight issue to resolve. We have a client who we are drafting an SLA for the delivery of telephony services using Asterisk. Nothing extraordinary. However, we do need a way to measure our service availability. We currently use Nagios and Cacti to monitor server availability as well as asterisk and mysql responsiveness, and last, "ping" availability to our

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

Hi All, I have 2 servers both running a compiled version of samba and winbind. They use my Windows Active Directory for user authentication via kerberoes. All that works fine and I can see and authenticate as any user. Every user on both machines have the same uid, the problem is the groups from the windows domain have different gid?s on each of the servers. I am using nfs to export the

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. Hopefully someone else will also attempt to answer your

I've just started testing Speex, and it seems very good so far. In testing the Speex decoder and simulating packet loss, I noticed that simply not calling speex_decode(st, NULL, output) when a packet is dropped doesn't appear to degrade the quality of the audio later on. The reason for this test is that in a real-time situation, you may not know right away when a packet is dropped

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.

How can one measure the effect of NAT traversal packet loss? We currently have no solution for NAT traversal for our SIP clients. There is no doubt that packets are getting lost. What is not clear is how much damage this does. On the face of it, everything seems fine. Could this be so? Perhaps we're suffering a degradation in quality or our call setup times could be improved. How can we

We are experiencing some packet loss between xen machines which we haven't seen before. Is this a problem anyone's run into before and/or has ideas on how to diagnose the issue? The setup is CentOS 5 xen-3.0.3-80.el5_3.3 Aaron -------------- next part -------------- An HTML attachment was scrubbed... URL:

Hi Lin, In addition to bug 6541114... Bug ID 6541114 Synopsis GRUB/ZFS fails to load files from a default compressed (lzjb) root ... I found yet another way to get the "Error 16: Inconsistent filesystem structure" from GRUB. This time when trying to boot a Xen Dom0 from a zfs bootfs Synopsis: grub/zfs-root: cannot boot xen from a zfs root

The issue: - raid1 will be in degraded state if one of its components is logical volume (LV) - raid0 will be inoperable at all (inacessible from within appliance) if one of its component is LV - raidN: you can expect the same issue for any raid level depends on how many components are inaccessible at the time mdadm is running and raid redundency. It happens because mdadm is launched prior to lvm

Had an idea, could someone please tell me why it''s wrong? (I feel like it has to be). A RaidZ-2 pool with one missing disk offers the same failure resilience as a healthy RaidZ1 pool (no data loss when one disk fails). I had initially wanted to do single parity raidz pool (5disk), but after a recent scare decided raidz2 was the way to go. With the help of a sparse file

I look after an x4500 for a client and wee keep getting drives marked as degraded with just over 20 checksum errors. Most of these errors appear to be driver or hardware related and thier frequency increases during a resilver, which can lead to a death spiral. The increase in errors within a vdev during a resilver (I recently had three drives in an 8 drive raidz vdev "degraded")

I am curious why zpool status reports a pool to be in the DEGRADED state after a drive in a raidz2 vdev has been successfully replaced. In this particular case drive c0t6d0 was failing so I ran, zpool offline home/c0t6d0 zpool replace home c0t6d0 c8t1d0 and after the resilvering finished the pool reports a degraded state. Hopefully this is incorrect. At this point is the vdev in question now has

Is it possible to install CentOS 5 with a degraded RAID 1 array using kickstart? I have the kickstart file already created but the "server" I want to use only has 1 hard drive in it at the moment. Until I can order a 2nd drive, I wanted to install the OS then once I received the replacement drive "fix" the array. I have seen instructions how to do this manually, but so far have

Hi! I wonder if the following scenario works: I have a mac mini running as an OSOL box. The OS is installed on the internal hard drive on the vdrive rpool. On rpool there is no redundancy. If I add an external block device (USB / Firewire) to rpool to mirror the internal hard drive and if the internal hard drive fails, can I reboot the system with the detached internal drive but with the
