[cisco-voip] 'interesting' EMCC behavior

[Erick Wellnitz]

I always forget about doing a packet capture on the phone.

I'm thinking it is cert related because on this one cluster the Publisher
is set up under servers using it's hostname instead of IP while all the
others are using IP.

We're going to change this once we get approval then re-export, consolidate
and import.
