My only suggestion would be you could reduce your line count by replacing
your GotoIf statements with ExecIF statements.
exten => addheader,1,ExecIf($["x${ARG1}" !=
"x"]?Set(PJSIP_HEADER(add,Route)=${ARG1}))
same => n,ExecIf($["x${ARG2}" !=
"x"]?Set(PJSIP_HEADER(add,P-Charging-Vector)=${ARG2}))
same => n,ExecIf($["x${ARG3}" !=
"x"]?Set(PJSIP_HEADER(add,P-Visited-Network-ID)=${ARG3}))
same => n,ExecIf($["x${ARG4}" !=
"x"]?Set(PJSIP_HEADER(add,X-C-Params)=${ARG4}))
same => n,ExecIf($["x${ARG5}" != "x"]?Set(PJSIP_HEADER(add,X-URI)=${ARG5}))
same => n,Return()

A human being should be able to change a diaper, plan an invasion, butcher
a hog, conn a ship, design a building, write a sonnet, balance accounts,
build a wall, set a bone, comfort the dying, take orders, give orders,
cooperate, act alone, solve equations, analyze a new problem, pitch manure,
program a computer, cook a tasty meal, fight efficiently, die gallantly.
Specialization is for insects.
