This customer want to use the Cloud desktop chat.
But, this customer doesn't use Cloud desktop chat.


<Customer firewall policies for Cloud desktop chat>

Permit port : TCP 443(does not permit TCP 5222)


This URL is written is the following.
"If 5222 is not available, use 443."


Log of Customer firewall has recorded "drop TCP5222 packet to".
