Unsure if this is related to upgrading FPBX to newer version but I'm finding our box is now reporting extensions as lagging. Have run connectivity tests, and mtr, cannot find issues with remote phones or connectivity at data center. FPBX is in Atlanta on linode, has worked fine until these recent problems. Please have a look and give me your thoughts.
