The issue of Cisco ACLs in and out may frustrate many users of Cisco hardware. When a packet first comes into an interface (leaving aside NAT and con table), it inspects the I bound ACL on that interface. To prevent internet access from Azure virtual machines you can either trust a host level firewall (ie Windows Firewall or Iptables) or you can simply remove the endpoints (which will also remove the ability to get to the machine externally). Workforce management is difficult enough in an inbound call centre, but when you go outbound it can become a lot more complex. If you implement these scenarios as described in the documentation, you'll use the default network access control list (ACL), which allows all inbound and outbound traffic.
