Description (partial)

Symptom:
In a mixed IPv4/IPv6 environment, a TelePresence Server may attempt to make use of an IPv4 address to contact an endpoint, even if IPv4 is not enabled on the unit. This will result in call failure.

Conditions:
*Mixed IPv4/v6 network.
*TS configured for IPv6 only
*DNS SRV set up serving both address types
*TS set to call direct with a DNS lookup URI
*DNS result returns IPv4 address ahead of IPv6 address
