I am using the 1.6 FS and facing an issue where the remote end GW suddenly sends incorrect timestamp on the RTP 

like below using PCMU

      seq = 34865, Time=4214993055   

      seq = 34866, Time=4214993215

      seq = 34867, Time=4134149926 

so when it gets the below time totally different (Without Marker) the FS inserts silence in the leg which is actually merging with the real RTP and creating noise. I can see that the remote end seems to be buggy but is there any way we can suppress the silence / noise generated from the FS side.
