[cisco-voip] Unity Application Error and Unity Ports

[Pat Hayes]

You can test an individual port by calling it directly. You would just need
to change the CSS on the phone you are calling from as, presumably, your
user facing CSSs can only call the pilot, not the individual ports.

You might want to also think about proactively applying the latest ES posted
on CCO.
