Thanks for the answer! I did so yesterday, but I do not understand why when using functions this does not happen, plus is there a variable in which all the Record-Route headers are saved from the query?

None of that should be the case. Record-Route should be added to initial invites only. And then it's the UASs job to copy the RR header into dialog-forming replies (e.g. 2xx).
