I'm with Lookin4Troubleon this one and think this is an AT&T issue (who I have also been with since Cingular).
New Motorola Atrix HD, working fine, left on a desk in a well serviced area having never left range of the tower to which it is connected. After a period of time although the phone shows full bars and a 4G connection, when a call is dialed from the phone it realizes that it is not on any network and re-initializes it's network connection, going through the various icons and network types until it gets to 4G and then the call goes out. While the phone is in that limbo state (full bars and 4G icon but not actually connected to the network) incoming calls go straight to voice-mail and no alerts for missed calls or voice mails are sent to the phone... until the process of making an outgoing call from the phone forces it to re-find the network - then incoming calls and voice mail alerts function... until the next instance. This happens several times a day and I have been unable to logically connect the problem it to any activity starting at the phone.
In the early days of 3G this used to happen a lot because the phones (referring to Motorola Razer V3xx) were unable to cleanly release a tower going out of range and attach to a tower coming into range as you traveled. Compounding the problem was the fact that the phones would not fall back on a different network band as they should have when the 3G connections were bad... because bad 3G connections were not being detected by the phone.
Same sh!t, different day! The new generation of 4G phones on AT&T are as bad as ever at falling back to the older network type when needed AND somehow the combination of AT&T and Motorola have managed to recreate this problem on stationary phones in good coverage areas. GOOD GRIEF.
