Provd upgrades for Cisco

I need to have some phone plugins upgraded

SPA 112 and 122 from 1.3.5(004p) to 1.4.1SR5

SPA8000 from 6.1.11 to 6.1.12SR1

Cisco 7975 to 9.4.2SR4

These are the latest Cisco firmwares and include many fixes including vulnerabilities.

If there is a guide that explains how to create plugins please let me know.
