rewrite the IP address in the SDP but that's about it. Technically<br>
that counts as "topology hiding". Other SDP parameters, however, will<br>
pass through and leak various bits of information about the endpoints<br>
behind the SBC:<br>
<br>
- Codec support<br>
- Payload types<br>
- Other "random" various SDP parameters<br>
<br>
Most real SBCs will rewrite the entire SDP (as FS does by default).<br>
<br>
Another thing to consider - the vast majority of FS users do not use<br>
proxy media (and most that do use it incorrectly). This leaves you<br>
open to the possibility that you'll experience strange edge case bugs<br>
using a media mode different from the majority of the rest of the FS<br>
user base.<br>
