WEEK 2 (12-16 APRIL)

This week was kinda exciting. Beginning of the week, I did some research on Session Initiation Protocol (SIP). SIP is a signaling protocol used for establishing sessions in an IP network. The protocol can be used for creating, modifying and terminating two-party (unicast) or multi-party (multicast) sessions consisting of one or several media streams. SIP responses are the codecs used by SIP for communication. The codecs that I focused was g729, g726 and g711.

After doing some research on SIP, the next day task was involving application on SIP. Firstly, I logged in into AsteriskNow server of this company and created an user extension. My extension number is 1115. Next, I downloaded free softphone XLite from the internet and configured the settings of the softphone. Finally, I tested the softphone by making calls to networked users. To hear the mail box messages, extension number 8888 can be dialed.

Besides that, I also learned about Host Media Processing (HMP). Dialogic HMP software performs media processing tasks on general-purpose servers without requiring the use of specialized hardware.


The next day, I was exposed to Welltech 6500 and Wellrec 5600. Welltech is the IP PBX system to operate on a variety of VoIP applications. The Welltech WellCIP 6500 series SIP Telephony server is the best choice to convergence VoIP network which convert the requirements from enterprise to service provider. Wellrec 5600 is a VoIP recoder for Welltech SIP network architecture.

My last task for the week was building a custom Interactive Voice Response (IVR). IVR is a technology that automates interactions with telephone calls. I downloaded Zoiper softphone from internet and configured the settings with my user extension. Then, I connected the IP phone and made phone calls from the IP phone to the softphone and vice versa.

WEEK 1 (6 - 9 APRIL)

Since this was just my first week, I learned the basics of telecommunication. Firstly, I learned how to use wavepad. Wavepad is an audio editing software that allow us to make and edit music, voice and other audio recordings. This software was kinda cool. It had many features like amplify, trim, reverb, echo, pitch change, equalizer and many more. We can change a voice to a totally different voice by doing some editing.

After that, I was assigned with my first task. My first task was to create an operator service (Virtual PBX). PBX used to calls answered with a custom business greeting, offer an audio scroll-through of your employee directory, provide a connection directly to a specific person or department, play music while the system is in hold, and even take voice mail for emloyees. Firstly, I google AT&T TTS and IBM. TTS is the creation of audible speech from computer readable text. Then, I typed out a speech text and clicked download. Next, I opened the downloaded wavefile in wavepad and edited the voice. Finally, the edited voice was uploaded in uniceed demo account under UC settings in multilevel Virtual PBX.

Besides that, I also learned about Web ticketing and online chat system this week. This was done by creating an account in supportuniceed/staffs and browsing the system. Other than that, I learned about Asterisk and AsteriskNow. Asterisk is an open source telephony project. It turns an ordinary computer into a feature-rich voice communications server. Asterisk includes all the building blocks needed to create a PBX system, an IVR system. AsteriskNow creates custom telephony solutions by automatically installing the "plumbing".

End of the week, I was required to create an user manual for uniceed. My friends and I divided the task to parts. I wrote the manual for UC settings which includes Multi-level PBX, call diverts to voice mail and Find me/Follow me. I was also required to edit the manual that I did previously to suit the VOS manual (Virtual Office Suite). The editing was done by replacing the relevant screenshots from UNICEED to VOS.

FIRST DAY OF INDUSTRIAL TRAINING (5 APRIL)

Today is my first day of my internship. I'm gonna do my 3-months internship at DARE BPO Sdn.Bhd. This company is situated at Plug & Play Technology Garden, Level 7 of The Gardens South Tower Mid Valley City. This company is based on Telecommunication. The product that DARE BPO offers is Unified Communication Service (UNICEED).

My working hours is from 10am to 7pm. Since it's my first day, I left my house early and arrived at the Gardens South Tower lobby at 9.30am. At the lobby, I met 3 of my friends who also got the same placement. After reaching the office, Mr. Jeffrey, CEO, gave us a brief introduction about the company and the services. Since it's a new branch, the office is very small and not many staffs. The main branch is at Cyberjaya.

Our Workstation for 3 months

After the briefing, we were allowed to log in into a demo account to try out the service from customer's perspective. I typed a message from the account and send it to my phone. I also tried other applications such as Find me/Follow me. If "Find me" is selected, incoming calls can ring simultaneously on three user-defined numbers. Whereas, if "Follow me" is selected, incoming calls will ring sequentially through three user-defined numbers. Besides that, I also tried the Virtual PBX. For example:
Welcome to ABC company!
For sales, press 1
For customer service, press 2
For technical, press 3

Trying out the service

After trying out the service, my friends and I went out for lunch at 12.30pm. After lunch time, Mr. Jeffrey went to the other branch in Cyberjaya. Before he left, he gave us the office key to lock the office at 7pm.
