Local number for me. Called on 11/11/15.
Also called from:
360-667-5263 on 12/02/15
360-841-7115 on 12/05/15
360-268-8118 on 12/05/15
360-886-3284 on 12/05/15
All local. All have caller ID "SSI."
I never answer and they never left a message.
BUT, a quick Google search turns up SSI as a market research company.
