Who called from 5154747120

Called at 8:30 on a Sunday morning!!  Was a fax machine.  Caller ID said "Iowa Call".

I got two from this number at 2am in the freakin morning!!!

Fax tone at 4:01 a.m. Caller ID reported this as "Unknown Name." 411.com says this number assigned to Ogden Telephone, Co., Ogden, Iowa, but Ogden Telephone says they have no 474 numbers, these are in Green Mountain, Iowa. Telephone provider for Green Mountain, Heart of Iowa Telephone Cooperative, is in the 641 area. This is apparently a fictitious number.
