It depends a lot on how large your organization is and how you are using your telecom system.
Some common ways to reduce data use:
- Block youtube, facebook, twitter, and similar social media oriented sites. These use a lot of data, but are not really work oriented. If people want to use these, they can use their cell phones and the associated data costs themselves.
- Block porn sites
- Block sports channels and sports games
- Block news sites that tend to play videos - example yahoo, nbc, etc.
- Block pop ups on the browsers
- Use browsers that don't support as much spyware, such as firefox and get rid of chrome
- Block most internet forums - I know - pretty painful, and some are actually quite useful.
- If someone really needs to use one of these site for a "work' reason, consider to have one computer available at the place of business that has access to these sites.
- Buy a television for the office and use an antenna or very basic cable service. In many areas, an antenna works just fine with digital TV.
Phone use:
- Consider to drop your internal phone system and give your internal users a flat rate per month to use their cell phones (maybe $20 - 30 / month)
- Use a service that allows central dial in and can route the calls to the individuals cell phones if needed.
Email:
- Outsource your email to a professional email supplier
Software as a service
- Skip these, they use a ton of data, cost a lot per month per user, and you loose control of your data
Computer software
- Consider to switch to Linux Mint or similar vs Apple or Windows. Linux Mint is very stable and widely used by firms and organizations.
- Consider to switch to LibreOffice and aware from MS Office. It is also very stable and most anyone can use it that knows how to use MS Office
- Many companies and organizations that are needing to reduce their cost (such as my company) have moved to Linux Mint and LibreOffice. It is quite a large savings compared to the user fees.
- There could be a few applications that will not run. For those, just setup one "central use" computer with those capabilities and ration it to 15 minutes per user per day. Sometimes people need a little help to move off of their traditions, but it saves a lot of money.
Consider to setup an internal "internet forum"
- Examples - CPF - a lot of data can be organized very fast, eliminating a lot of emails
- Behive makes a very low cost internet forum software pacakge that is easy to manage.
