Hi Aditya
I think this is valid from protocol and offer answer model .But its
actually driven by use-case.
*Usecase 1* :Normally during call(sendrecv :media flowing both ways) if we
put call on hold (no music on hold) with inactive
then *while resuming ,we put sendrecv*.
*Usecase 2* :But for the scenario where media flowing one way(sendonly)
like Video Share or Image Share from User A to User B
And call is put on hold using inactive then* while
resuming will put sendonly* again .
*Usecase 3 *: *With MOH *
User A(sendrecv) <--------------------In call------------------ > User
B(sendrecv)
A holds(sendonly)------------------one way hold(MOH)--------- - > User
B(recvonly) listening to music
A(inactive) <--------------------------2 way hold--------------- User B
holds(inactive)
*Now 2 cases possible depending who resumes firs*t
*When A resume first:*
A resumes(recvonly)------------------still call held from B--------- - >
User B(sendonly)
A(sendrecv) <--------------------------Both way active--------------
User B resumes(sendrecv)
*When B resume first:*
A (sendonly) <------------------still call held from A--------- - --- User
B resumes (recvonly)
A resumes(sendrecv) -------------------------Both way active-------------->
User B (sendrecv)
*So while resuming call , both users putting recvonly.*
Hope this helps
