I am looking to update my key responsibilities in my CV for for my previous job to suit the requirements of this new job I am looking for. 
In my previous job I was an IT network engineer. Within that role I managed and monitored remote networks.  This included setting up various services such as DHCP, DNS, VPN's, Firewalls, Routing & Switching, VLANs and networking. I was also tasked with diagnosing network problems within a clients site and had to resolve them quickly. I had to determine the best hardware/software route for clients that would provide them the best value for money. This also meant I had to keep up to date with the latest security patches and how often they are rolled out. Frequently within this role I dealt with customers over the phone as well as being on site. My role also required me to produce high quality documentation into clear and accessible content.

With the above points mentioned about my previous duties, please create a bullet point list of 6 key responsibilities that would suit my new role as an IT Network Engineer within a large organization.
