Re: [sr-dev] [SR-Users] Obscuring SIP traffic and using with NoSIP

by Muhammad Shahzad

The key purpose of ITV encryption is to avoid making a pattern of any sort. If you encrypt same text / packet 10 times you will get completely different encrypted text / packet each time. This happens due to the fact that the encryption key changes dynamically with each new encryption done, see the readme file for more details https://github.com/mshary/itv/blob/master/README.md Secondly with v2.0, it uses non-deterministic random source as well as auto-learning, so it can adopt to new symbols and words encountered while encrypting and update itself to use them. So technically, it can also be used for binary data such as RTP, however RTP uses UDP which has possibility of packet loss and thus not suitable for ITV encryption (at least for now, this is a hot discussion within my researchers circle and we are actively looking for a solution for this). See release notes for v2.0 here, https://github.com/mshary/itv/releases/tag/v2.0 Anyways, the current target is to use kamailio as SIP proxy and doubango as SIP client for iPhone and Android. Once it is achieved it will be available free / open source to public and then it can be actually tested against all possible voip blocking and sniffing scenarios which we hope it would be able to solve with minimal possible overhead. So far the prototype works pretty good in a few voip blocked countries and GSM operators where we have tested it. Thank you.

Dialog module issue on OS/X

by Olle E. Johansson

I could not load the dialog module, because of a linking problem with the symbol destroy_dlg. Found that it's declared "inline" twice which may cause an issue. With this change, that I don't dare to commit myself, I could load dialog and explore it. Can someone take a look at this, someone that understands dialog and stuff? This was on OS/X.
