Configuring Network and Session Initiation Protocol (SIP) Features

The IP phone uses the information in the Global Session Initiation Protocol (SIP) 
settings to register at the IP PBX. 
The IP phone configuration defines network and user account parameters that 
apply globally to all SIP lines. Since not all SIP lines are necessarily hosted using 
the same IP-PBX/server or user account, additional sets of per-line parameters 
can also be defined for network and user account.
You configure and modify these parameters and associated values using the 
configuration files, the IP phone UI, or the Aastra Web UI. The Aastra Web UI 
and configuration file methods configure global and per-line SIP settings on the IP 
phone. The IP phone UI configures global SIP settings only.
On the IP Phones, you can configure Basic and Advanced SIP Settings. The Basic 
SIP Settings include authentication and network settings. The Advanced SIP 
Settings include other features you can configure on the IP Phone.
