[cisco-voip] Naming conventions for Expressway-C / E

I try to stay away from uppercase, numbers and hyphens /special chars in hostnames (just superstitious like that).

Example Edge:

expedgea.domain.tld
expedgeb.domain.tld

This is the FQDN that will resolve to LAN2 on the inside with internal DNS and then the outside public address in external DNS if you're doing an Exp deployment going with CVD best practices, using the dual interface.

Example Control:

expcontrola.domain.tld
expcontrolb.domain.tld

Beyond that, it's really whatever makes sense for the business. I try to stay away from "themeing" (I.e using Greek Mythology in hostnames ... Ex. expasgard.domain.tld, thor.domain.tld). Aside from the novelty, it's like getting a bad tattoo.... you end up regretting later or trying to cover it up with alias records in the SAN field of the certs.
