Release or Identify Stuck Call

I sometimes see calls that have been waiting in excess of several days. Obviously this must be a stuck call. How can I identify that call and release it?

Hi Gordon, for that, you would need to speak to Support as there is nothing customer-facing currently within the platform that will allow you to do this.

We are aiming to include a line viewer in the web interface for the next version (v5.7) that should allow you to do just that…

Sam, Jonathan,
thank yo for the response. I have raised a ticket with support to clear the offending call(s) and am looking forward to 5.7 when we might be able to do this ourselvs.
