I was tinkering with Asterisk and the Festival text-to-speech engine, and wrote some short Asterisk::AGI scripts to read back live weather reports. After that, I thought I needed something more interactive to work with... Then I had a flashback to 1996, first year university, standing in the C & O club at the University of Waterloo, where someone had just pulled out their US Robotics Palm

This Wednesday, November 26th, the Toronto Asterisk Users Group invites all in the area to join us for a telephony workshop and talk sponsored by Sangoma Inc.[1] Jose Landivar, co-founder of PaloSanto Solutions[2], creators of Elastix, will be running a "getting started" workshop on Elastix, followed by a talk discussing how it differs from other Asterisk-based distributions, and a

I believe you can assign processors in vmware, and xen as well. So you could probably do something funky like that to try to reduce load. The only thing that probably becomes difficult is trying to manage physical hardware between virtual machines.

Hey All, I've been working on trying to get asterisk to play nice under Xen and I've run into a bit of a road block. I'm not using any hardware stuff only ztdummy. First I had issues getting ztdummy to work but that was solved by recompiling the xenU kernel to have CONFIG_CRC_CCITT=y which it was missing. Now ztdummy is seen fine in the virtual machine though when I run

I'm looking for some software to do emulation of phones so that I can test out a whole range of phones and their firmware revisions against asterisk. Anyone know of something like that? I'm hoping that the hardware vendors have something like that, and _maybe_ I'm really lucky and they are using something somewhat standard like qemu. Cheers, spd -- | It ain't what you

Hi, I have one physical server (server1 - CentOS 4) and one vmware (server2 - CentOS running in a VM under Windows 2003). I'm running PHP/MySQL webapps on it. I want to be sure there is a failover, but I don't really need load balancing for now. I run php/mysql/apache with the binaries that comes with CentOS 4. I have installed heartbeat on both and set MySQL replication so that

Hi, I am running CentOS 5.3 32bit as a VirtualBox 3.0.0 guest running on Windows XP. The Windows host CPU usage is constantly at 50% although the CentOS guest is completely idle (i.e. 0.00 load average). I know this is a common problem related to the 1000Hz frequency that the CentOS kernel runs at. With previous versions of CentOS, I used the kernel-vm package [1] and it solved my problem.

Hi, I''m new in Xensource World. I have to work on Xen 3.1.2 hypervisor, I''ve done some searches on how to make Xen HA (not FT for the moment).The way that is come again and again is to make a cluster with Corosync, pacemaker, DRDB. I just want to now if there are others way to do Xen HA, and which is the best way in your opinion?I need something very stable and sustainable.

Hi Dean. Thanks for your reply. The ADT library is exactly what I end up replicating. My library started 2 years ago and at the beginning, what I needed was very different from LLVM. My first containers were: - A custom std::vector that does not initialize elements to 0 for int, double, etc. This is very important in HPC for the first touch policy used on NUMA architectures. It also allows

Ok here is a real geek question, I building my own linux kernel for my asterisk system and came across the kernel setting for the timer frequency. I have one of 3 hardcode choices 100Hz, 250 Hz and 1000Hz. From what I understand the default Freq was changed from 100Hz in kernel 2.4 to 1000Hz (1KHz) in kernel 2.6. Timing is a BIG issue in asterisk with all the TDM and zap channel stuff.

on i have a small question we have a linux box with a windows 2003 server well we natted all the ports and mail is working remote desktop is working web is working the only thing that does not work is vpn how can i foward vpn traffic to this server i checked the site and searched for foward vpn and got nothen can somone please enlight me where to start Marshal McInnis Tech / Web

Hi, Let me present myself : I work on High Performance Computing, mainly on number crunching where the languages used are mainly Fortran and C++. This field is moving more and more from pure number crunching where Fortran shines to a mix of numbers, texts and other data that you cannot easily deal with Fortran. Unfortunately, the C++ standard library suffers from its age and the fact that it has

Hi All, I am using a Grandstream BT100 and I have been trying to get the PBX features to work for DND, call foward, etc. These functions do work when I use my POTS phones hooked up to my Zap cards. But I cannot get the PBX functions (ie *78, *79) to work using my SIP phones. Is there a feature that has to be enabled to do this? I know these functions are available within the GS phone but all of

Hi, I'm building a test asterisk server and building the latest kernel I got to wonder if there are any specific recommendations about schedulers and so forth for optimum performance. There are a few areas that raise questions in my mind and I wonder if anyone has any opinions/comments on which settings are most suitable for use with asterisk: SLAB Allocator (SLAB or SLUB?)

Hello everyone, We are developing a new version of a satellite telemetry distribution system currently in use in the European space industry, and are trying to convince the client to permit us to use Rails as the platform for the higher-level layers of the system. The system as a whole has strict high-availability requirements (our current track record is over six nines yearly), and in order to

Hi All, I am currently researching on doing high availability and load balancing with a couple of Linux servers, most specifically doing service takeover on top of Heartbeat. The scenario is: - 2 DSL lines from a single provider - 1 Broadband line from another provider Internet / | \ | | | /

Hello guys, We've been having some problem setting up the High Availability for Vicidial and Asterisk with CentOS 5.3. The VoIP quality are degraded and systems becomes so unstable. Are there are other better options. Thanks.

Hi, We have three machines (server-A and server-B and client) and mounted server-A (6GB) and Server-B(6GB) under client (/mnt/) as 12GB with unify option. Then we have stopped glusterfs on Server-A.Now client side df command shows 6GB. Now,while trying to create files under /mnt produces this error message "Transport endpoint is not connected" Server-A is still down - Is it possible
