[Freeswitch-users] SIP REFER - URI Parameters

I’m trying to use FS (1.5.8b from last week) as an SBC and load-balancer (using mod_distributor).
It is load balancing between several FS conference nodes.
It’s working a treat, apart from one scenario :
Say conference xyz is already running on conf-node-1.
Next incoming call is sent to conf-node-2, pin is collected, and conference xyz is identified as the required conference.
Conf-node-2 checks presence, and sees the conference is already running on conf-node-1, and does a deflect.
We add some query params to the refer-to URI to tell conf-node-1 not to collect the pin, but put the caller straight into the conference.
e.g <action application="deflect" data=“sip:1234 at 10.1.1.2;conf=xyz" />
In the REFER I can see the params :
Refer-To: <sip:1234 at 10.1.1.2;conf=xyz>
But they are not present on the request URI or To header in the INVITE to conf-node-1.
So conf-node-1 requests the PIN again.
Is there any way I can pass this info to the other conference node by using the REFER?
Thanks for your help.
