It can be done with or without media. FS does not relay SIP messages transparently as OpenSER, but act as a SIP UA to each call leg. This gives an oportunity to place rtp in between streams, do call recording and all other softswitch stuff. I use FreeSWITCH as hosted PBX solution, basically hosting multiple SIP domains each of them representing a separate PBX for a different company with separate dialplans etc.

This is also interesting for me, as I love freeswitch, and maintaining a
single platform is easier, than handling various different ones.
In the past years I did a couple of projects with OpenSER /openSIPS.
These projects comprised:

   * registrar for the SIP user agents
   * handle invite messages (+ ringing, bye, ok, etc also of course)
     between registered user agents and user agents at external domains
   * rtp payload was a bit different from usual VoIP traffic (video
     parts, application sharing, file downloads etc.), but SDP was fine
     according to RFC, and OpenSER mediaproxy worked also
   * handling of peer-to-peer presence (SUBSCRIBE, MEASSAGE, OPTIONS)
   * The number of messages to handle was not that much (some thousand
     subs).

For my understanding this should also be possible with Freeswitch with
bypass_media. Right?

Best regards
