=> No, if FS doesn't act as server (from a TCP perspective - not SIP), FS doesn't need and has no certificates at all. Connecting to a trunk via *flows* (this is standard 
(here) for trunks for home / private or small business internet customers (usually behind NAT)) doesn't need any server part at all.

That's exactly what's used by homer (heplify-server). Or sngrep. See my other post regarding those tools.
