[Freeswitch-users] Sofia recover and wrong Sip fields when sending re-invite

Hello list
I was able to setup HA cluster with two FS boxes, and if my primary crashed
sofia recover is triggered on the second box. However i have noticed that
second FS box sending the Re-Invite incorrectly.

My FS boxes setup is extremely simple, when i receive a call i forward it
to the Opensips proxy, so i use bridge like this: (public dialplan)

   <condition field="${sip_to_user}" expression="(123456789).*$"
      <action inline="true" application="eval" data="URI=${sip_to_user}"/>
      <action application="set" data="domain_name=$${domain}"/>
      <action application="bridge"
data="{absolute_codec_string=PCMA}sofia/internal/987654333 at"/>

So what FS does, its sends the INVITE to the opensips like this: (stripped)

INVITE sip:987654333 at SIP/2.0
Via: SIP/2.0/UDP;rport;branch=z9hG4bK5N320Bvar00ZN
Max-Forwards: 68
From: "Grigoriy Dobrovolskyy" <sip:33811740 at>;tag=3jNgatZH4D92Q
To: <sip:987654333 at>

The call is answerred, and all is going fine, i crash this box and trigger
box2 to reinvite the call,  FS2 gets the same ip and send Re-Invite like

INVITE sip:;transport=udp SIP/2.0
Via: SIP/2.0/UDP;branch=z9hG4bK62a7.6041d237.0;rport
Max-Forwards: 68
From: <sip:987654333 at>;tag=B2B.511.202
To: Grigoriy Dobrovolskyy <sip:33811740 at>;tag=3jNgatZH4D92Q

Notice the FROM and To field, we are sending the invite to a proxy, from
this proxy, this has no sence, it should be:

From: Grigoriy Dobrovolskyy <sip:33811740 at>;tag=3jNgatZH4D92Q
To: <sip:987654333 at>;tag=B2B.511.202

Is there any way i can fix this with some kind of param ?
