Normally I don't answer these calls b/c I don't recognize the numbers but I did just to see who it was and to let them know not to call my home again.  The guy on the phone claimed to be taking donations for the police department; police do NOT take donations that way.  I explained to him it's Sunday morning and I'm trying to get to church, never call me again!  This is a scam people, do NOT fall for this scam!

Answered the call after three rings and all it was is silence.

no message, caller id reported baltimore, md which is not a 667 #

Check again. Area code 667 is an overlay for the same codes used by 410 and 443 that started in operation back in 2012.
