Thank you for this please back to this channel

Excellent

Good presentation

Really good overview. Thorough, still easy to follow/understand - and this goes to your other videos as well. I have been dealing with VoLTE for a few years now, and it would have been good to have such a good summary back in the days :) Beside engineering, are you also in education/consulting business ?

Brilliant explaination, presentation.....can you plz just make a video about fixing ims not registered issue

Vikas does a great job of taking complicated procedures and protocols in an understandable step-by-step fashion. One thing is for sure, you know your subject matter and know how to relate this to your audience. With my deepest gratitude, thank you!! Vikas, I have one suggestion on the production side. The voice compression on your annunciations on your "s" sounds are sometimes a bit over-powering. It would be a fantastic idea to upgrade to a higher quality microphone. I use the Samson Stage PXD1, a wireless USB lapel microphone. It seems well balanced. You put a lot of work into your presentations, you deserve to have a really good microphone. Please don't get me wrong. You are a great speaker, and I can understand you very well. But the high-pitched ring caused by certain speech patterns limit the amount of time for continuous listening. Also, if you lower the volume on your intro music jingle, at the beginning of your videos, it will also be a significant improvement.

Very Nice

thank you so much

thx u very much👍

Thanks, man!

Hi, Your vidoes are very nice for concepts. Inrefernce to this, our organization has given your website link for core employees to learn the VOLTE concepts.

Hi Vikas, do u have any slides on LTE, as these slides are on VoLTE, or this playlist is good enough to learn both LTE and VoLTE?

Great

thank you for your great work on IMS , could you please provide material pdf or ppt ?

thankyou sir

Nice

Good idea give about ims core, application server and transport layer

You presented CSCF as P-I-S (CSCF). On VoLTE Architecture common scheme (11:45 min) there is no link betwen P-CSCF and I-CSCF. That's way P-S-I (CSCF) may be more correct for inderstanding. What do you think? In any case your video is so good. Thank you very much!

Please make video on python & c Programming ,which is used in protocol development /testing with interview question.

hi I have a question on xcap. Call barring.. Is there a way to have a chat with you mate?

Thank you for the information can you please help me with the standard documentation for announcements flow in IMS by 3gpp

i really have this question, i wanna know where they put the HLR or HSS "server"? like what do they call that place(center, tower, hq)

IT'S GOOD VIDEO

hi vikas can you do more videos on diameter protocol and PCRF

Can you please make a video in LTE explained in depth

Mapping of 4G network with IMS and the connectivity of network elements of 4G with those of IMS? This is a question which we got in class. Can you help on how to answer this question

Sir, Could u pls explain in hindi also....its much easier to others who wants to learn in hindi or searching in hindi @telecomtutorial

ahcha... thanks

Is there any videos for SIP?

Sir, please provide one video for VOWIFI netchnology

When USIM itself having binary (i.e. SIP user agent) capability of deriving IMPI and IMPU, then why we need ISIM? what made ISIM more suitable for VoLTE? Awaiting for your reply. Thanks.

would you explain trans-coding little brief ? Grate video looking forward to watch other videos as well

Can u make something for ims security. Overall

Kindly make this video in hindi for smooth understanding .Thanks in advance..

Very nice explanation but some times your going a bit speed .. reading the sentences fast.

Can u pls explain,what is meant by CODEC?

Please add link to slides!!

✌️✌️✌️✌️👍👍👍

Can you give the pdf of 4g network.

Awesome Vikas ..I need some help . 1. Can some one tell me how many conformance test cases for each architecture element 2. Time it takes to run these test cases for each element of architecture 3. Preferred network simulator for each element of architecture .

Users may be served by various sip server while only one sip server serves the customer.... did not understand this 😕

Hi sir, is there any way that you have a flashcards or quizzes regarding this lesson? Very informative. Also it's good to have some strong sense of knowledge by answering questions. Thank you.
