[cisco-voip] PSA: Hunt Groups and Alerting Names

[Anthony Holloway]

I tried the double quote trick at first, based on a forum post I saw, but
it didn't work for me.

In the same post, someone posted a sample Lua script, but that also did not
work for me, so I wrote my own.

Post in question:

YMMV.
