(Salem, OR) -- The Oregon Department of Human Services will be upgrading the phone system used for the ONE Customer Service Center this weekend. It's used for providing support with medical, food, cash, and childcare benefits. Access to the call center isn't expected to be disrupted, but there could be longer wait times through August 25th. Instead of using the call center, they're asking people to go online to benefits-dot-Oregon-dot-gov or visit a local office.
