I've recently been exploring Oracle's Cloud offerings while looking to migrate a website from an Amazon EC2 instance.  After struggling with troubleshooting connectivity through Oracle's Cloud seemingly straight forward security offerings, I found the default Ubuntu image has iptables configured as well.  It restricts all ingress except port 22 for SSH.Given I rarely dabble in iptables,

I was recently asked to set up a simple telephony IVR with six options and provide the ability to report on which options were chosen by callers.  In UCCX world I would use a Set Enterprise Info step to write a custom variable and then report on it later.  Here, since some of the IVR options were already being served by Webex Contact Center I wanted the IVR and reporting to be a
