You can use a property having an array of Strings as value:

MERGE (a:Person{number:'123'})
MERGE (b:Person{number:'456'})
MERGE (a)-[r:CALLED]->(b)
ON CREATE SET r.duration = ["100-200->500"]
ON MATCH SET r.duration = ["100-200->500"]

Later on when adding the second duration value, use

MERGE (a:Person{number:'123'})
MERGE (b:Person{number:'456'})
MERGE (a)-[r:CALLED]->(b)
ON MATCH SET r.duration = n.duration + "200-100->600"

N.B. the "+" operator on an array amends a new element to the array.
