We have had an rather annoying, but not show stopping, issue with FOP2. Sometimes, calls which are parked "disappear" from the parked call list in FOP2. The call is still parked, and can be picked up by dialing the appropriate parking extension, but FOP2 does not show the call. Also, sometimes calls which were parked, do not clear from the park slots list when they are picked up, until you refresh your browser.

We are using the built-in Asterisk blind transfer to put calls in the parking lot (#1)
We are using an Asterisk system installed from source, our versions for Asterisk and FOP2 are:
Asterisk 1.6.2.14
FOP2 2.11

Thankfully, this is the only issue we are having, and any assistance in resolving this would be appreciated.
