2.4 parking lot issues

when i hit ## (trixbox 2.2.10), using freepbx 2.4, and i dial 70 for the destonation, it says “that feature is not available on this line”

check to make sure that you have the latest parking module, the latest framework module and then make sure that your features.conf file got replaced by the new one that should be linked from core. The framework update is suppose to remove your old one so the linking is successful. The parking features got moved, they used to go in parking_additional.inc, now they go into features_general_additional.conf.
