NE #81 SIP Call Conference Explained

In this video, we are going to use Wireshark to look at a SIP 3-way conference call. The call flow will be, A calls C, then B calls A, followed by A conferencing with B and C. We will be using our SIP testbed we built in video #65 for this testing.

I ftp'd all the wireshark traces to: muxall.com/docs. The call conference trace is: AcallsCBcallsAAcnfBandC.pcapng

[@kanishkjain2767]

Then what is the significance of JOIN header
is that not required for SIP conference

[@abhishek-xv5ow]

cool

[@anotheryoutuber7122]

I guess you didn’t explain what happens in background when it elevates from peer to peer call to conference, there is crux n more interesting stuff to explore mate. 👍

[@nizarworld2020]

Two things missing.refer messages and confrence url.ple elaborate in detail.conceptual intersting one.thanks appreciated

[@anshularora5403]

How many Call-Id will be there for the conference call?

[@muxallopeniot9194]

That is a good question. I guess it depends on the SIP phone's capabilities.

[@rdineshtadikonda8825]

Hi, I am not able to download the traces.. can you please help me?

[@muxallopeniot9194]

Hello Raja, Sorry about that. We move hosting providers and I guess we broke the doc section. I'll see if we can get it fixed and I'll let you know. Thank you for letting me know that link is broke.
