<br>
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.<br>
<br>
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).<br>
<br>
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.<br>
