Ring group/follow me stopped working. Calls are disconnected: v. 2.11.0.27

Hi all.

Ring group functionality recently broke on a system that’s been running OK for the last 6 months.

The issue seems to lie with dialparties.agi. In the log snippet you can see that at 15:33:32 dialparties.agi is launched, but seems to never execute, causing the call to eventually time-out.

I tried setting up a new ring group to no avail. The issue also breaks the follow-me feature.

Calls connect OK when sent directly to an extension.

The PBX admin has been altering the order of extensions in the ring group twice a day… Could the config have become corrupt?

Relevant SW versions listed below.

Thanks!
