At 26:24 SDP = Source Description Packets ? How it get Email Address of the sender ? Instead its known as SIP URI and SDP is actually Session Description Protocol that contains info about Call behaviour and codecs details etc. Please consult proper resource instead of memorising literature.
Question: when you're going over the RTP header notes you stated that "RTP itself does not provide any mechanism to ensure timely delivery of packets", but when you're discussing the Time Stamp you make note that it looks at the timing sampling the first byte to remove jitter, which the excessive timing between packets. Would be able to clarify? It seems that the two statements contradict each other. Wonderful video's by the way. Keep up the good work.. :-)
Brian Thomas hey not sure if you still don't have this answer but hopefully I can clarify. Basically what the prof said is true RTP does not have any mechanism to ensure timely delivery itself but you will find most VOIP phone manufactures implement something called a jitter buffer to remove unwanted jitter. This jitter buffer is implement in addition to standard RTP and it relies on the RTP time stamps to know what to do. So RTP is not ensuring the timely delivery of packets but it is making it possible to remove jitter if you would like too.
Abdi Bulle thank you very much for the clarification. I'm always learning it it's very helpful for someone like yourself to aid in putting the pieces of the puzzle together.
that was the clearest explanation about RTP , thank you
I have no works to thanks you. Your way of explaining is excellent. Thanks a lot.
Thanks for the lesson. Still valid in 2020.
Also in 2024.
very helpful video.....takes a lot of effort..well done

Good one.. worth spending 50 mins.. Thanks
Very Good conceptually.

Brian Thomas My pleasure. This has always been an job/interest of mine and I love to see people show interest in telecommunications and engineering
Thanks for the Explanation

how do you watch this? IT says WMG content, cannot watch it.
Great lecture!
Thanks professor.
sir thank you.i am waiting for your IMS network.
lecture
nice bro
