I receive Invite from vendor with i  need to forward to a destination ip set in special header X-Dest without changing the RURI.

When I try to bridge this invite 

  <action application="bridge" data="sofia/external/${destination}@${sip_h_X-Dest}" />

It changes the RURI. I need to preserve the RURI but set destination to X-Dest header. 

How can i forward call to that IP without changing the RURI. 

Best Regard.
