Help Asterisk!!!

black1e

Hi
I was wondering if anybody could help me with asterisk. I have only been using linux for two months - intalled Ubuntu 7.04 (the first disk) and I am trying to install asterisk. It is for my college project to have two machines connected using crossover and capture a few voip packets. I downloaded Asterix but came up with errors - think I need to get openssl and bison and a few others - like I said I have only been using Linux for a few months and hate to say it but don't even know how to get those packages or install them- so used to windows. If any body could offer me any pointers in this regard would really appreciate it as I have hit a blank wall at the moment and my first project synopsis is due before christmas

I can't claim to have used VoIP much at all so can't help you much on that front

I suggest you download the latest version of Ubuntu, 7.10 [code-name "Gutsy"].

How are you installing the software you need? Use the Synaptic Package Manager to install all software. Only install by source if you have to, i.e. if the package isn't in the repositories set up for your machine.

Heres a run down on how to install asterisk on,

Ubuntu

Debian

Red Hat / CentOS

Whats the aim of the project - You want to trunk 2x asterisk servers and have calls going to and from each other?

Why does it have to be a cross over cable, use a small switch and connect up a couple of IP phones.

Thanks for all the replies, the project is an intro to VOIP and besides the research the practicle side is to get a voip package talking in a server/ client role and capture some packets and look at them using wireshark. Basically if I can get asterisk on one machine to call another machine and capture some packets. I wanted to use skype and windows but the instructor said that woudl be too easy. I had a laptop and a desktop - so I thought that this would be the best /cheapest implementation

All I want to be able to do is PC to PC calls - is this easy to configure and can it be done with asterisk. Does it use IP or another naming configuration to identify PCs? Yep think I am in over my head

If you just need to capture some SIP traffic, why don't you sign up to something like freespeech.ie, get a SIP client for Linux and capture your traffic that way instead of going through the rigours of setting up a complete Asterisk environment?

Its more fun - setup your asterisk server with FreePBX this is quite simply to accomplish, I wrote this script a while ago to to install asterisk + freePBX you should be able to modify for the latest version, let me know if you have any issues.

Appreciate all the advice guys and ye both seem to know a lot about linux. I am going to use the synaptic package manager to see if I can download the extra packages I need and hopefully that will sort out my installation worries. Can you let me know if it is possible to configrue asterisk to do PC to PC calls and if so how is it done? Two machines, one crossover cable, asterisk on both - set to a 10.1.1.1 and 10.1.1.2 with a headset. Can it be done ?
