Add function to update TRAU muxer after assignment or handover
E1 based BTS use TRAU muxer to decode TRAU frames. After changing channel from one timeslot to another (due to handover or assignment), the TRAU muxer must be updated. The call reference of the call is disconnected from the old channel and connected to the new channel.
