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. Ognjen On Fri, May 22, 2009 at 2:37 PM, Peter P GMX <Prometheus001@gmx.net> wrote:

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?

Hello,

FS by design is B2BUA, and it cannot route INVITEs and other SIP methods. It can however, bridge a-leg to b-leg with or w/o media and doing plenty other cool stuff much better than commercial projects. I suggest joining us on irc to detail your setup so we can help you.

Hi all,

I want to use FreeSWITCH as a SIP transparent proxy in session border controller application. Please let me know the changes in configuration files required to achieve this behaviour

Thanks very much for the help.

Regards, Sridhar
