Hello Daniel,
Do you have an idea why the SIP messages header are only partially encrypted for the caller ?
Since both SIP clients connects to the same SIP proxy it means that SIP messages go two times through the same proxy (client -> proxy -> registrar -> proxy -> client), is it possible to configure topoh to encrypt headers only for outgoing messages on a particular network interface ?
this is possible only in current development version, you need to add an event_route and based on the target ip or local socket ip you can decide to apply topoh or not:
https://kamailio.org/docs/modules/devel/modules/topos.html#idp44483268
Current development branch will be released as v5.1 in few weeks.
It is not clear if partially encrypted messages means that the proxy has decryted the already encrypted header parts and encrypted the parts in clear ?
I will have to look at the code, not remembering by heart what can happen in case of a spiral... The overall goal was to hide the details of caller and callee from each other...
Cheers, Daniel
