Hey there. It was a great video with clear explanation, and thank you for making this video. Just a quick question: At 9:14 after the IPv4 address what does the "/127" mean? If it's an IPv4 address, it should be the subnet mask, that is below 32, right?
Actually, I looked this up, and it said it is a TTL Limit, so we can avoid a packet being circulated between routers, because when the TTL of the packet gets to 0 (after 127 hops), it gets dropped by the router.
Is SIP a part of the session layer? all I can find online say the application layer, even within the OSI model, but this to me makes no sense as SIP deals with initiating, maintaining and terminating real-time sessions.
Thanks for watching everyone! I hope you enjoyed this series.

My pleasure!
I have been taking the 'SIP SCHOOL' SSCA course. The quality of your content is amazing as a free version :)
Thanks Keith, that's great to heat :)
@@NetworkDirection so is it application layer or session layer? What's the difference between origin and c fields in SDP
Outstanding overview
Thank you for your clear explaination!

Yeah, I thnk so. I just think of anything that high up as 'upper layers'
First of all thank you so much!
Can you share any source about voice networks (books etc )?
