datacom introduction
- August 28: went over sylibus and been introduced to Thomas hicks who has a vast wealth of knowledege far beyond much of my conception but i plan to deadicating much of my personal studies into 2 areas including physics and computer sience (datacom) studies
- August 30: installed debian sqeezes on two mechinesa dn using a voip system known as astrisk made a 3rd box hold the main astrisk server and switch board system
- Week in review: interesting and seemly full class dedication to the Voip and astrisk phone project installed sqeezes on two mechines and astrisk@home and a 3rd will connect them eventually to make 2 switch boards and the astrisk box the root for communications with in the lair
- Week enlightenment: very little instructions for a localized phone system using astrisk i have found several im parting to out side communications such as inbound and outbound calling in in regards to accutal tele phone call relays not just a single room communication
Entry 2: September 4&6, 2012
- this is the frist class after a long weekend lets see if were still at all focused on the single room phone project
- this day will prove that those who are intrigued and involved with this endevor will be enthralled and driven to complete the asigned tasks to see this localized lair telephone project to is conclusion. (yes big words [wont do it agian do too many major spelling errors] )
- we have been able to set up two sip phones via a trunkcated mechine with 2 personal lab tops one running OSX and the other a distributation of linux to run sip via pc to pc how ever the cisco sip phone gave the class and instructors complications along the lines of registering the phone with the trunk aka the truckcated machine.
- week in review:good day good progress alot of scripting confgiuering and setting up a small local lan PBX system using asterisk how ever still having problems with accutal phones aka cisco sip phone 7941 model
- week's enlightenment: never use cisco netowkring equipment over priced and limited functionality
Entry 3: September 11&13, 2012
- September 11th i was in history class when the trade towers were hit by two large domestic commerical cracft and 2000+ die i am here in the lair now learning and having fun a full 11 yrs later today i learned that each computer with voice or sipphone has its on extension and and music can also be put into the system
- this is significaant for the fact that we now have a extension system to which we can communicate each other with mutiple calls on a single router/box/asterisk system we can also eventually use google voice to call out of the lair for free
- i am currently waiting for wedge our fearless x-wing piolet to instruct me on the proper documentation to read from for the installation of a commucations system(the script being used and modified to use google voice with asterisk) that connects the Millennium Falcon to the other x-wing squadrands(lair)
- comming up with a adapation to implement to the asterisk project to participate(thinking about apllying custom ringtones as you call some one not as they call you)
- the 13th we goofed off did resreach and tested the load compacity and compatiablity of asterisk with other outside sources aka google chat and skype
- well if you are able to run muytiple calls with out cross connection and as well as connect to an outside sorce like google chat u can eventually connect to the normal land line services
- im some what behind the others i feel that i havent contributed as much and would like to do more modifications of the asterisk systems and other systems
- just the lack of personal contribution i feel i should be douing more but i have very little idea where exactly is this leading or any idea of what we are trying to do

September 18
- What action or concept of significance, as related to the course, did you experience on this date?
- We experinced the frist call to a 10 digit number form asterisk across google talk to the cisco sip phone
- Why was this significant?
- this is great due to the fact that now we have access to at least localy routed 10 digit phones
- What concepts are you dealing with that may not make perfect sense?
- the fact taht we have a 10 digit phone working wouldny it allow us to to call out but for some reason it dosnet
- What challenges are you facing with respect to the course?
- not much minus trying to keep up and follow what Saad is doing he hasnt accutly left any documents to go by (fyi he will always have a job job security at its best right here)

Keywords

VoIP. Voice overlay Internet Proticol
Definition
a system and internet proticol that allows to transmite and receive human voice form one place to another much like the telephone which is analog but in order to use it via computer and the interwebs you need to digitize the sound wave length, tone and pitch of a human voice then transmit via the VoIP system which im not intirely sure of all that happens.

MAC Address
Arp
Definition
Mac address is the physical address put into and on a computer for its entire life this is not an IP which can be change no a Mac Adress is hard coded into the computer or networking device to reference it for future service such as allocating an ip to a network on the computer on either a WAN or a LAN. Media access control address ussaly given in a hexidecimal form
How to Find a Mac Address on a Windows XP Desktop PC or a Notebook PC • Click on START, and then click on RUN • The RUN dialogue box will appear. Type CMD and press ENTER • A DOS window will appear. This is also commonly called a Command Prompt • Now type IPCONFIG /ALL at the command prompt and hit ENTER. This window will now display the configuration of all of your network adapters. If you have multiple network adapters in your PC you'll see multiple addresses. The MAC Address you're looking for will be listed under the heading Ethernet Adapter Wireless Network Connection • Now look for the Physical Address. It should look something like 00-50-BA-D1-BA-71 • To close the window when you are finished, type EXIT at the command prompt and hit the ENTER key

Demonstration
Demonstration of the indicated keyword.
If you wish to aid your definition with a code sample, you can do so by using a wiki code block, an example follows:
/* * Sample code block */ #include <stdio.h> int main() { return(0); }
Alternatively (or additionally), if you want to demonstrate something on the command-line, you can do so as follows:
lab46:~$ cd src lab46:~/src$ gcc -o hello hello.c lab46:~/src$ ./hello Hello, World! lab46:~/src$
Experiment 1
Question
is there a known method to connect two analogue phones together to communicate with out the use of phone services or systems
Resources
no internet resourses how ever this experiment is one that has been done in the past in the same place by multiple inviduales all including the elusive presley suarues who has extensive experince in the home made cob job of analogue phone to phone
Hypothesis
based on observatuions of preveouse atempts and experinces i belive that this is not only achiveable but easaly done knowning the right peramiters (ie an educated guess based on the facts known).
State your rationale.
Proof of previvuse exdperimentation and serveral retests and tests never been recorded however to my knowledge
