<p dir="auto">topoh was designed for interconnect, where redirects are usually not allowed. Propagation of contact header can disclose the topology on redirect, usually being a telephone number @ the domain/IP of the server hosting the target user.</p>
<p dir="auto">Anyhow, I see potential usefulness in specific cases if that is fine from privacy point of view for whoever runs the service, so I added the option to turn on propagation of contacts in the 3xx replies. See the commit referenced above, mask_mode param has to be set to 1.</p>
<p dir="auto">This is a new feature and is not going to be backported. If it is not working, open a new issue providing relevant data using the latest master branch.</p>
