In your case need 1) increase ptime value to 40; 2) use codec without compression; 3) need to enable VAD feature; Also you can route torrent client network traffic via VPN together with VoIP traffic. This will mask VoIP packets and not allow math your traffic to VoIP profile on ISP equipment. вт, 19 февр. 2019 г. в 19:53, Bipin Patel via FreeSWITCH-users < freeswitch-users@lists.freeswitch.org>:

i would like the ask the community about VoIP encryption, currently in few middle east countries VoIP is officially blocked. The isp are so aggressive that they use all sorts of fancy tools to block it including skype calls, whatsapp calls etc and are very successful in doing it. So far companies like voipswitch and recently few others have been providing tunneling mechanisms to get over this but recently UDP traffic is heavily filtered and they go to the extreme of checking packet length and pattern and artificially introduce delay, jitter or simply block it if the number of hits are high. Switching to TLS/SRTP also doesnt help, it works with some isp but as soon as you try same using mobile data it stops working coz they match packet length and block based on the profile. ZRTP doesnt work coz a normal RTP streams needs to start and then it starts encrypting it but those initial RTP get blocked.
With lack of any more VoIP encryption protocols its almost getting impossible to bypass block so has anyone have any ideas of any other modern form of encryption which can be used for VoIP (btw VPN are also blocked and more over if packet size increases then nothing works on mobile data).
The market demand of skype replacements is also extremely high coz skype, hangouts, whatsapp video, instagram video, viber etc etc, u name it and its blocked.
