Aastra Telecom 41-001343-02 User Manual

41-001343-02 REV04 – 05.2014

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.

For more information about Basic SIP Settings (for authentication and network), see 

.

For more information about Advanced SIP Settings, see 

 on 

Specific parameters are configurable on a global and per-line basis. You can also configure specific parameters using the IP 
Phone UI, the Aastra Web UI, or the configuration files. If you have a proxy server or have a SIP registrar present at a differ-
ent location than the PBX server, the SIP parameters may need to be changed.

The IP phones allow you to define different SIP lines with the same account information (i.e., same user name) but with dif-
ferent registrar and proxy IP addresses. This feature works with Registration, Subscription, and Notify processing. This fea-
ture also works with the following types of calls: incoming, outgoing, Broadsoft Shared Call Appearance (SCA), Bridged 
Line Appearance (BLA), conference, transfer, blind transfer.

The following tables identify the SIP global and per-line, authentication and network parameters on the IP phones.
