The IPs marked as ''NEW'' were added in August 2014 for room for a planned expansion. Customers should add these additional IPs to their firewall rules as we expect to be using them soon.
'''SIP''' is the call routing information that creates and manages calls. In practice if you allow port 5060 from the outside world you'll see attacks and possibly receive spam phone calls. We do not recommend leaving 5060 open unless you really know what you are doing. Phones rarely use ports as low as 5060 for media.
