IP Phone Administrator Guide
SIP Settings
The following paragraphs describe the SIP parameters you can configure on the IP
phone. SIP configuration consists of configuring:
• Basic SIP Authentication Settings
• Basic SIP Network Settings
• Advanced SIP settings
• RTP Settings
• Autodial Settings
Notes:
1. 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 different location than the PBX server,
the SIP parameters may need to be changed.
2. The IP phones allow you to define different SIP lines with the same
account information (i.e., same user name) but with different registrar and
proxy IP addresses. This feature works with Registration, Subscription,
and Notify processing. This feature also works with the following types
of calls: incoming, outgoing, Broadsoft Shared Call Appearance (SCA),
Bridged Line Appearance (BLA), conference, transfer, blind transfer.
