Alright - so I had it working for a while this afternoon and I just got on to test after playing with the pipeline for a bit and got this:
8:31:25 PM PhoneCall Error executing call 'sBq69OT5-1367980255861@Thing1.mtregional.org’
java.lang.InterruptedException
at java.lang.Object.wait(Native Method)
at com.inductiveautomation.alarming.notification.sip.call.CallManager$PhoneCall.run(CallManager.java:335)
Any ideas? Is this a Skype issue or internal?
