[cisco-voip] re-genarate certifications

[Brian Meade]

You still are going to have issues with phones that were offline when the
new cert was pushed.  For a large regen project, we just plan to have
everyone make sure their phones are online but you can't do this every
couple of months.

With websites, people don't have persistent connections as well so it's
easy to switch certs.

Anyone know of any persistent services able to use technology like
Let'sEncrypt without dropping connections?
