I wouldn't answer any calls from this number.  Yes, my opinion is based partially upon instinct, but I have also been observing the calls we get during the day for the past six months. Caller ID showed this call was from Awa Doumbya.  I did not answer the phone as some telemarketing scams track and document numbers that habitually answer phone calls.  Our voicemail message states our number before asking the caller to leave a message.  As soon as our voicemail recording played through the phone number to the part where it asks to leave a message at the tone, the caller hung up.  Suspect they were tracking.
