I think it's entirely possible that you know more than the AT&T engineers that i spoke with. So, you should call them and tell them how to fix this "bug" you found.

Well
of course the "tech" would never just buffalo his way thru it enough satisfy you (just hypothetical of course) because maybe has no idea what the problem is and might be just a service rep not an engineer.
Not saying this is the case but criticizing someone else's theory all because a company that wants your money "said so" is just crazy thinking. (SMH) I hope you don't still decide that things must be true based on one person saying so.. Although, hey if you do would you believe I've got some ocean front property for sale in Arizona at a special low price just for you.. Well, of course I'm telling you the truth. I mean you did read it on the internet didn't you.. and we all know the internet doesn't lie. B-)
 
Has anyone tried updating your roaming capabilities? Seems to have stopped it in my boyfriend's phone (old Nokia.. and yes he's way behind the times Lol) temporarily anyhow. Also activating call forwarding to our home number or even the smsc number (carrier backdoor for messages basically) then deactivating it again seemed to work only temporarily. I have to agree it wouldn't be anything to do with the number you're calling being forwarded as it pops up before it even connects. I believe it is in regards to your call waiting features and while it's connecting hasn't recognized yet that the call waiting is activated due to line being busy. His voicemail is not even set up so doubtful it's anything to do with that either. Seems logical that yes it's a programming glitch that for whatever reason has the system check too soon for call waiting status. Therefore it's checked while it's "busy" dialing out. I'm no expert though just taking a logical and somewhat educated guess.
 
I just recently switched to T-Mobile from AT&T and my friend Caitie still has AT&T and was not getting my voice mail whenever she called me. I read about the call forwarding activation thing on the internet and dialing ##004# and call. I have never heard of this before. I tried it with my phone several times with solving the issue. Then I came across this site and question as why the call forwarding pops up and read the reply. I decided to try it on my friend's phone. Bingo!! She got my voice mail with no problems, however, she continues to get the message call forwarding but without issues. Thank you for your help.
