Hello,


We would like to use FreeSwitch to test interoperability with our sip registrar platform - as our registrar doesnt handle NAT Traversal we would like to use FS as a mirror proxy .


If a call goes through, FS should transparently handle nat traversal functionalities while forwarding the REGISTER/INVITE requests to our registrar server.


Below some detailed requirements:
Upper Registration is the capability of a SBC to proxy Registrations towards an upstream Registrar. While it is necessary that all SIP requests traverse the SBC for NAT continuity, Registrations should be allowed to be relayed towards our upstream Registrar while the SBC retains a copy of the AOR and masquerade on behalf of the UA that send the registration request.


Please let us know the best way to configure FS to achieve this type of configuration.


Thank you

FreeSWITCH is a B2BUA and NOT a proxy and will not proxy any requests (REGISTER or INVITE) If you want a Proxy you should look toward OpenSIPS From: sylver_b <sylver_b@yahoo.com> Reply-To: <freeswitch-users@lists.freeswitch.org> Date: Wed, 26 Aug 2009 17:14:55 -0700 (PDT) To: <freeswitch-users@lists.freeswitch.org> Subject: [Freeswitch-users] upstream Registrar / Mirror proxy Hello, We would like to use FreeSwitch to test interoperability with our sip registrar platform - as our registrar doesnt handle NAT Traversal we would like to use FS as a mirror proxy .

A proxy won't do what the original poster is asking for. Upper registration is a special type of function performed by SBCs and not defined by any RFC yet but there are drafts out there. This question comes up quite often in various mailing lists and has been asked this list before. The answer is no freeswitch can't be configured to do this as it stands today.

The only opensource SBC I know of that attempts to do upper registration at the moment is OpenSBC.  Otherwise there's vendor SBCs like ACME packet, Nextone (now Genband -  they call it Mirror Proxy mode) etc which do it.

Steve
