[Ekiga-list] =?utf-8?q?Hello=2C_ekiga=2E?=


Dear Ekiga,

This is Kang, from Korea. I am currently a student in a college in Korea and studying WLAN and VoIP.

I am writing this mail to ask for some things about ekiga. I and my friends are studying VoIP and preparing my project about

improvement of QoS in VoIP in Linux. I have picked this software as the Application to test my study. I have istalled it manually by using open sources.

Before I ask, please be kind because there is a litte problem to understand what I am saying, I have poor English;;

The first thing I want to ask is that in source i want to find where the packets go through the transport layer after encoding step.

To Improve VoIP QoS, I want to first know the audio packets' path on the sources. I can see many functions on sources so, it is very

difficult to recognize how the packets are passed. Could you please let me know which cpp files cover this mechanism?

Secondly, I have tested ekiga on Infrastructure with two laptops and I got those to connect with an Access Point in my room.

Using 'Wireshark' as you know, Packets capture tool, I captured the packets, but the protocol of packets is H261, video codec protocol

and Type of service is '101' which is video type. I did not even use video function when I call my friend.

I think that ToS should be '111' or '110'.

Lastly, if I had a chance to test by changing sources and apply the changes, which steps should I go through?

I do just ./configure, make and make install. Are there more things I have to do?

That is all what i want to ask you.

Thank you for reading this email and I expect your reply as soon as possble. I will attach a picture about my question.


Sooil, Kang.
