Week 2

12 April 2010:

Today I did research on Session Initiation Protocol (SIP). It is a signaling protocol, widely used for controlling multimedia communication sessions such as voice and video calls over Internet Protocol (IP). The protocol can be used for creating, modifying and terminating two-party or multiparty (multicast) sessions consisting of one or several media streams. The modification can involve changing addresses or ports, inviting more participants, adding or deleting media streams. I am suppose to focus on codes g.729, g.726 and g.711

SIP Proxy Server

13 April 2010:

Today I was asking to create a SIP account on asterisk and setting up X-Lite. First I need to log in my company asterisk server to create a user account. Then I need to download soft phone X-Lite from internet. My extension number is 1234. At last, I can call other user. For mail box message, can dialed 8888. Other than that, I also did some research on Host Media Processing (HMP). It is a software-based technology which replaces hardware telephony boards. These boards did all the media processing work and had special interfaces for connection with PSTN. Gridborg HMP, since it is software-based, requires no special hardware and runs on PC. Connection with PSTN is established using VoIP technology.

Soft phone X-Lite

HMP was introduced, telephony boards can be replaced with a software running on PC and using VoIP for PSTN connectivity.

Week 1

6/4/2010 :

Today we learnt how to use wave pad and virtual PBX. Firstly, we use AT & T Labs Text-to-Speech or IBM to generate voices by typing the text in the message box. Next we can download the voice and browse into wave pad. IN wave pad we can modify the signal and editing accordingly.

7/4/2010:

Today we learnt about asterisk and asterisknow. Asterisk is most popular open source telephony project. It also a software that turns an ordinary computer into a feature rich voice communication server. Asterisk includes all the building blocks needed to create a PBX system, an IVR system or virtually any other kind of communications solution.

AsteriskNOW makes it easy to create custom telephony solutions by automatically installing the "plumbing". Much of the complexity of Asterisk and Linux is handled by the installer and the administrative GUI. Application developers and intergrators can concentrate on building their solution. AsteriskNOW was built for application developers, systems integrators, students, hackers and others who want to create custom solutions with Asterisk.
