I have been assigned to establish Voice Over Internet Protocol

Server “VOIPS”

---------------

-On 19 of October I have a dissection with my supervisor En.Bander in SabaFon  about

establishing VOIP Server project . During the dissection my supervisor explained to me with details what is wanted exactly

1-What VoIP Server they want..?

2-What is the purpose of this server..?

3-Where this server will be used..?

4-Does the server need to be access from outside the network or only in the ring of the Lan..?

The upshot of this dissection and the details i get about this project was as follow:

First, the VoIP server needed in order to facilitate the mobile means of communication among the staff,  the wanted server will be used for making a communication network with the staff Mobile cell phones.

Second, there must be a unique number for each Mobile phone of the Staff, these numbers are giving and managed by the VoIP server ,means that there is not two staff used the same number.

Third, the server must not used any internet connection, only Wifi signals should be used for transmitting the voice and video and connect all the staff mobile phones to the network of VoIP server

Fourth and last, the project must be done within two weeks start by 19 October end with 30 October ,and i have to set this server up with all of the details ,then implement it as a pre_implementation with some of the staff in the department to make sure the server works well and there is no any vulnerability.

So, since my supervisor clearly explained to me what is wanted,

also advice me about some points and references will help me such as SIP protocol.

Since that, I start to read about session initiation protocol "SIP" and find more resource about it.

-19-20 October Read about Sip protocol .

-21-23 October Read about VoIP and find out Sip server .

-24-26 October Read and watch YouTube videos on how to set up OfficeSip server, as well installing and configure OfficeSip server.

------------------------

I found OfficeSip server which provide good quality of

communication, I watched YouTube videos and read some references about VoIP including OfficeSip server, find out  how to install, how to add and manage users for the clients, also how OfficeSip server works.

So far, OfficeSip  server installed and run the service, then i set up the configurations such as opening the used ports by OfficeSip server which are: Tcp5060 Udp5060 and adding the users in the server to be accessed by the clients.

----------------------

What still left are,

a-  Finding a router and configure it in order to connect the clients to the server network  that happning after

passing the identifying and verifying process, as well giving an IP for each client, means  the DHCP has to be active on the router.

b- Finding the client software which going to be installed and configured on the staff phones.

c- Test the server with the staff.

Almost 60% of the project done.

I assigned for a task which is establishing and finding more details about voice over internet protocol server , this task  should be done within two weeks start by 19 October end with 30 October. So when i finish  this task i will explain with details Inshallah...

This day we understood how the intelligent network in the company helps in managing many services moreover, having knowledge about these services.

Defination the term of "intelligent network" is a system which manage and control a group of software, the

main aim of the intelligent network is, providing the latest telecommunication service to the subscribers.   The intelligent network in the company manages many tasks some of them are as follow:

1- Prepared card service “PPS”

This service allows the subscribers “after entering the card No” making the local and international calls.

So the value of the entered card “credits” depreciates equally with the cost of the call.

The subscribers also can with this service check up their remaining balance..etc

The advantage of this card is, losing its value after a fixed times of wrong card Number entering.

2- Prepaid phone service “PPT”

This service we can define it as, credit is purchased in advance of service use, means as pay as you go, and depends on the customer paid amount.

The advantages of this service are,

a- Alerting the subscriber within the call that his/her balance is not sufficient to extending the time of the call.

b- After the phone hang up from the other party, the subscribers can have voiced report about their call.

3- Postpaid phone service, the subscriber in this situation is billed after the fact according to his/her use of mobile services at the end of each month.

The disadvantage of this service is the high bills that customer get at the end of each month.

4- Free phone service “FPH”

This service is used from some companies in term of business, marketing advertisements as well it used from some of official bodies, for providing information and helping people like police station..ect ----------------------- Read at home about these services:-

5- Voice mail system service “VMS”

6-Vot- Tele voting service

This day we have an idea about the balling system. This system process the accounts, balance of all the postpaid customers, this system get the data feeds from the smart network system or what called CDR. the CDR after each call has to do the following tasks: a- generate the calls time b-generate the ph.number of calling c- generate the ph.number of customer d- generate the calling time by seconds e- the real duration f- the calls cost So. as it explained the billing system gets the data "calls time, number of calls, calls cost...etc from the CDR then the system of billing process this data in order to manage the balance of the customers as well generates the bills

In this day we visited the server room and there was a a brief  explanation from one of the staff then, we back to the IT operation unit ..

Today they gave me a task to be solved, which is the questions in the paper down...

in this day we visit the unit of Vlaue-added service which is for non-core services or in 
short we can say it's the unit which is in charge for all the uncore services or extera 
services such as song ringtone, sending SMS to the TV..etc
