I used an open source program to do VOIP tests. Do you have any idea on how to measure the delays? On Sun, Jan 30, 2011 at 5:21 AM, Martin Visser <martinvisser99 () gmail com>wrote:
Vineeth, I think you have you work cut out for you. Skype is a proprietary, unpublished protocol. Skype uses its own encryption scheme to boot. As such you can't really tell a request from a response, (if there is any), so I really think you won't get very far. If this is the beginnings of some sort of research project into voice quality of service, you probably want to concentrate on looking at more open protocols.

Ihaveto measure the latency of the packet from source to destination and for which I need their time stamps. I see that all my voice chat follow theudpprotocol and I am not able to find their time stamps. I just find the arrival time of the packet and not the time at which the packet was send from the destination. I believe the udp message must be converted to RTPinorder to do this analysis am I right? If not can some one tell me abetterway? I am basically trying to collect a real time data of how users chat whenitcomes to a group conversation. I am attaching the captured file with this email. Any help isappreciated.Thank You Vineeth___________________________________________________________________________Sent via: Wireshark-users mailing list <wireshark-users () wireshark org Archives: http://www.wireshark.org/lists/wireshark-users Unsubscribe: https://wireshark.org/mailman/options/wireshark-users mailto:wireshark-users-request () wireshark org?subject=unsubscribe___________________________________________________________________________ Sent via: Wireshark-users mailing list <wireshark-users () wireshark org> Archives: http://www.wireshark.org/lists/wireshark-users Unsubscribe: https://wireshark.org/mailman/options/wireshark-users mailto:wireshark-users-request () wireshark org ?subject=unsubscribe
