Hi Tufail
With test call you mean call to a an answering machine which talks all the time (for example exact time). Then you don’t have DTX in DL direction and the RxFull is correct. If you have DTX (normal voice call) then you have periods of silence where nothing is transmitted except the TS code. The RxFull will take into account also the silence with Q = 7; RxSub takes into account only training sequence and this is the correct value.
