A bill collector getting info.  Probably Receivable Performance Mngmt.  Located at 10501 SE Main St Portland, Or.

this is a scam outfit have been getting random calls I believe they are trying to get personel info

Have been receiving calls from this number for more than a few weeks.  When I answer there is a long delay before someone picks up the phone (3-5 seconds) and it sounds like a call center environment.
