Hi Daniel
after lookup location call, the UA from register is made available in the $location_ua for the contact set in r-uri and $(branch(location_ua)[INDEX]) that gives it for additional branches. Maybe you can get it in branch route as well, if branch index is 0, then is the r-uri, the next branches are built from additional branches after lookup location.
Thank you!
$location_ua is correctly set in the branch route. This saves me having to use the XAVP including associated database overhead.
$(branch(location_ua)[$T_branch_idx]) does not seem to work in branch routes in 5.7
Mit freundlichen Grüssen
