Description (partial)

The TCP connection to the Expressway may drop. This may drop all active dialogues across this TCP connection including, but not limited to calls and registrations.

This will occur if the Expressway receives a warn-agent header where the value matches a pseudonym and not a hostport as defined in the as defined in RFC 3261. This commonly means that characters that are not allowed are included or the warn-agent starts with a number. Only alphanumeric characters and hyphens are allowed and the value cannot start with a number.
