Agent status doesn't change to available activity while doing outbound call

[AmyKHwho]

When we use this outbound dialpad plugin, we found sometimes the agent status doesn't change to availalbe activity automatically, thus the outbound task can't be set up successfully at agent end, meanwhile at client's end it looks like the call is holding. When issue happens, agent also can't end the call since the hang up icon disappears, agent has to refresh the page to end it.
There are suspicions that sync map update doesn't always happen.
The issue is intermittently.

I know we ran into similar issues at some point and think we found a workaround. We weren't sure if there was something we added on our end to cause this to happen but it sounds similar to an issue we saw. To resolve it we modified the file
plugin-flex-outbound-dialpad/dialpad-functions/functions/outbound-dialing/callStatusUpdateHandler.protected.js

And removed the if statement here,

// We dont need to know about calls that are completed as this is the natural part of the life cycle after the call has been answered
  if (event.CallStatus !== "completed") {
    updateSyncDoc(context, event).then(() => callback(null, response))
  } else {
    callback(null, response)
  }

to just always call
updateSyncDoc(context, event).then(() => callback(null, response))

I have a feeling that the sync doc wasn't properly updated everytime a call was completed so when another was trying to be made it wasn't handling it properly. Would be curious to get @jhunter-twilio feedback though
