Defines the type of IP Group: 
  [0] Server = Used when the destination address, configured by 
the Proxy Set, of the IP Group (e.g., ITSP, Proxy, IP-PBX, or 
Application server) is known. 
  [1] User = Represents a group of users such as IP phones and 
softphones where their location is dynamically obtained by the 
device when REGISTER requests and responses traverse (or are 
terminated) by the device. These users are considered remote 
(far-end) users.

represents an IP-PBX, Application or Proxy server that serves

IP Group is proxied to the Serving IP Group. For registrations, the 
device updates its internal database with the AOR and contacts

Digest authentication using SIP 401/407 responses (if needed) is 
performed by the Serving IP Group. The device forwards these 
responses directly to the SIP users.
