Nokia 3120 icon question

Archived from groups: alt.cellular.cingular (More info?)

I have a N3120 and lately I notice that there is a
very unusual icon not described in the manual.
When it goes to screen saver mode where it
shows the time, there is an icon at the lower
left corner underneath the lock icon. It has
a right arrow and an handset icon to the right
of the arrow. What is this icon? I thought that
this is for voicemail message waiting icon but
it is not!

Thanks in advance.
