Can I configure rules to manipulate the sigalling on input and on output of FS?

on a limited way, like adding and deleting some headers

for a complete control and manipulation of signling, you put a proxy (eg OpenSIPS, Kamailio) in front of FS.

To cope with NAT traversal issues, must I configure FS with a systematic relay of the media streams or is it possible to configure FS so that it relays the media streams only when it's necessary?

FreeSWITCH has best NAT traversal management in industry, and yes, you can configure it to relay media only when needed.
