[@kuldeepsharma-nk2ws]

Explanation is good .. its should be little slow ... Seems like reading book fast fast

[@prashumrn]

What is 100 trying?
Why not used 90,20,10 and etc instead of 100???

[@ujjalsamanta5841]

by 183 in progress both parties negotiate codec then why send again sip UPDATE ..pls help me sir .i dont understand this particular point

[@TelecomTutorialinfo]

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

[@indiancreator77]

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.

[@mohanradu]

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.

[@indiancreator77]

Dear, pl go through the sip flow carefully ,when codec negation happened with respect to which msg along with resource reservation .

[@Yoyo-ck9pm]
