[SR-Users] Topoh module configuration for SIP proxy and SIP registrar

[Christian Conus]

Hello Daniel, 

The headers in the callee logs contains encrypted data which is exactly what
I expect but when I look at the caller logs I can see that the headers are
partially encrypted and they contain the ip address of the registrar that I
want to hide in clear.

In the following message from the caller log, the Record-Route contains the
ip 10.3.3.26 which is the registrar. I would expect at least this ip address
to be encrypted.

The behavior that I expected from the topoh module (enabled on the proxy)
was to encrypt headers for all SIP messages for both caller and callee so
that the ip address of the registrar never appear in clear in any SIP
message going from the SIP proxy to a SIP client.

Thanks, 
Christian
