VoIP ID Installation
● Follow installation instructions
– Things to remember before starting
● There are 12 steps that need to be followed correctly and in order
● The manual is for Ubuntu server 14.04 or 15.04 so you need to prepare one of
them. I suggest not to waste your time by asking the manual for other distro, you
can always try them on your own once you have experience completing this
manual
● I was using VirtualBox when writing the manual, you might consider using it too
(vs install on real server)
● You need to connect to the Internet, you will download lots of packages
● Again, follow the manual correctly and in order. Stop if you don't understand or
need to discuss something or experiencing errors. Join the VoIP ID Facebook
group and discuss your problem there
