asterisk users - Jun 2019 - can Asterisk 16 handle silence suppression from ITSP

Hi:
     my ITSP use G.711 with VAD and it can not change the settings. I
was using Asterisk 13 but the voice quality is not very good. I don't
know if asterisk 16 is good enough to handle this kind of situation?
or I still need FreeSWITCH in front of Asterisk to get good voice?

     thanks a lot for help!!

Regards,
