I got a call from this number on my cell and no message was left and when you call it back it's out of service.

Only idea as to what this might be is a random number generated auto-dialer to see if a number is in service before a telemarketer calls.  As it has shown up on caller ID multiple times with no message and calling back to what I surmise is a spoofed number gets the "not is service" message.

I've gotten 2 calls from this number on my personal cell phone, one today and one yesterday. I don't answer numbers I don't recognize.

Our caller ID list is growing larger.  Each time phone numbers such as these call relentlessly and hang up we add then to our phones as DNA1, DNA2, etc for DO NOT ANSWER!  Our cell phone provider charges $3 per number to block and with the growing number of 'estranged numbers' that call us we have to deal with it.  When I called this number back it says 'out of order'

I got the same as above.............silence, then "Thank you, good bye."

I keep getting calls from this number and when I pick they hang up .   The caller ID said  Roberta Saddler

How can this number stop calling me? I get this "good bye"  call everyday!

This number keeps calling me i get the same thing when i answer a few moments of silence then an automated voice that sais " GOODBYE"

I got a call from 406-352-3346 on my cell when i was driving my bus when i got done with my shift i called the number back and it says its no longer in service and they left no message. this was on 4/23/2012 3:27pm

Today I was getting maintenence in my home and i got a call from 406-352-3346. It was on my homephone and it showed the person was Saddler, Roberta. Well I answered and said hello a few times then it said "goodbye" in a voice auto-mated machine. I dont know what to think of this call because I get calls all the time from a random number and they dont say anything but this one freaked me out. Oh yeah this call happened at 4/10/2012 4:14 pm
