Hi,
Can a UAC send RE-INVITE , if a response is pending from UAS for
UPDATE refresh Request in early dialog .
Is this applicable , if yes can you please point me where/which RFC
explains this.
Here is the Call flow , is the below call flow is acceptable ,
UAC(A) UAS(B)
-----------------------INVITE----------------------------->>
<<--------------------100Trying--------------------------
<<---------------------183/SDP-------------------------
------------------------PRACK-------------------------->>
------------------------UPDATE------------------------>>
<<------------200 OK (for PRACK)-------------------
<<-----------200 OK (for INVITE)---------------------
---------------------------ACK--------------------------->>
-----------re-INVITE without SDP----------------->>
<<------------200 OK (UPDATE)--------------------
<<------------200 OK (INVITE)------------------------
---------------ACK with SDP------------------------>>
Thanks
