For those interested in learning more about "Amanda", the Echo software used to make these calls: http://cironline.org/reports/when-it-comes-fundraising-shes-machine-5546
MrNumber.com shows a lot of "Amanda" calls from this number (mostly solar panel scams). Whycall.me has only one complaint about this number and it's the "student debt relief" scam. So it's either one scammer running several cons or just several scammers spoofing the same phone #. My money's on the latter.
