Active Call stuck on system

[liftow]

Weird issue - and not really an issue at all.
One set called another yesterday afternoon at 4:00 PM and had a brief conversation. Call still shows as Active in Call Assistant and in the Live Calls admin section.
It doesn't show up on either phone.
I've rebooting both phones but the call is still there.
Will try rebooting Allworx server tonight which I'm assuming should clear it up.

It doesn't appear to be affecting anything at all, and isn't using up any outside lines. Just odd.

Allworx 48x v7.5.3.2
Both sets are 9212L v2.5.5.9
Both are at a remote WAN site.
One runs G.711, one G.729 - that's the only thing out of the ordinary... but they've called each other before.

Didn't get around to rebooting the server last night, but that stuck call is now cleared.
Maybe there is a 24 hour call duration limit or something...
