New Icon - missed call?

[bergman]

Two or three days ago my iPhone 5 began displaying a new icon at the top to the right of the AT&T and signal bar. It looks like an old style telephone handset with an arrow pointing to the right. I've never seen this display previously. I'm guessing it might be a missed call indicator of some kind, but it doesn't go away after looking at the recents. Anyone know what it really is? This is my 5th iPhone and I've never seen this icon.

Call forwarding is enabled.

Thanks. Some sort of glitch. Call forwarding wasn't actually enabled and calls were coming in just fine but opening the settings for CF made the icon disappear.

If you're jailbroken, apps like IntelliscreenX and Lockinfo use a similar icon for missed calls. So if you have one of those installed it could be that.
