   git remote add upstream git://github.com/dhublerSIPfoundry/sipxecs.git (note the read-only url, there is no chance to write on upstream)
   git remote
   return: origin
           upstream

git checkout master-4.2 //move to master-4.2 branch
git fetch upstream //get latest code from upstream
git rebase upstream/master-4.2 //rebase your local master-4.2 branch repository with upstream
git status //to verify if your local branch has something that needs to be pushed to origin
git push origin +: //push on origin

NOTE: In order to automatically update a specific branch (master-4.2)),
instead of git fetch upstream it is recommended to use:
git pull upstream master-4.2
This command will automatically align your master-4.2 branch with the upstream master-4.2 performing automatic rebase

git checkout master-4.2  //move to master-4.2 branch
git rebase TEST //push TEST changes on top of your master-4.2 branch
git push origin +: //push your local master-4.2 branch on origin
