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,

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.

Regards,
Ognjen (sekil on #freeswitch).

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
Peter

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.
