@ Vikas .. It's really worth watching your videos. I have noticed that Prack & SIP update message not specified by Ericsson and Nokia Documents you explained very well ..Keep it up !!
Thanks for the video, very informative. One thing need to be confirmed: there should not be a "2nd offer" in the PRACK from A to B. In RFC 3312, there is no SDP Offer/Answer in PRACK/200 OK (PRACK).
sir ji understand thanks ...sir pls make a video with wireshark ..if you kindly clear how to route header file attach during reg time ...how enum quey has done plss give a deep knowledge sir..god bless you
Great Video , Superb content on volte .. It's Comprehensive & complete volte guide at one place . I was looking for such a detailed explanation on volte sip call flow since long , appreciating your efforts . also tell me when your next video will be coming
sir make a video of prtocol testing ims nodes how tester analysis these pprotocol through wireshark and QXDM. and what is deployeement and how to deployee these nodes. waiting for your response
Nice explanation, Can you also explain VOLTE call flow between ENodeB, MME and SGW. Like how the dedicated bearers are established in the above manner. Would be much helpfull.
Originator (A) Party user sends 3rd Offer Request to B party with Update Request depicting Resource Reservation status . Here , Originator will perform critical Task of Reserving resources & Will send Update request without changing rest of Parameters such as Codec etc.. . Since Codec have been already Agreed between both Parties via PRACK Message discussed Earlier , Same Selected Codec will be used in this Offer without Any further changes
Little easier.... Invite - Contains A-Party supported codecs,183 Progress - contains B-Party supported codec list & Update - Finalized/Agreed codec list which will going to use in particular that session. Great graphical VDO Vikash sir.
Still don't understand why this can't be done in a two way process: SIP invite from A with list of codecs and also resource reservation on A side. SIP reply from B with selected codec (based on what it received from A) also with resource reservation on B side.

by 183 in progress both parties negotiate codec then why send again sip UPDATE ..pls help me sir .i dont understand this particular point
Originator (A) Party user sends 3rd Offer Request to B party with Update Request depicting Resource Reservation status . Here , Originator will perform critical Task of Reserving resources & Will send Update request without changing rest of Parameters such as Codec etc.. . Since Codec have been already Agreed between both Parties via PRACK Message discussed Earlier , Same Selected Codec will be used in this Offer without Any further changes
Little easier.... Invite - Contains A-Party supported codecs,183 Progress - contains B-Party supported codec list & Update - Finalized/Agreed codec list which will going to use in particular that session. Great graphical VDO Vikash sir.
Still don't understand why this can't be done in a two way process: SIP invite from A with list of codecs and also resource reservation on A side. SIP reply from B with selected codec (based on what it received from A) also with resource reservation on B side.
