Advanced IP Phone Operational Features
Advanced Operational Features MAC Address/Line Number in REGISTER Messages
The IP phones can send the MAC address and line number in the REGISTER
packets making it easier for the call server when a user configures the phones via
the Aastra Web UI or the IP Phone UI. The following two configurable headers
send this information to the call server:
Aastra-Mac:
Aastra-Line:
The MAC address is sent in uppercase hex numbers, for example,
00085D03C792. The line number is a number between 1 and 9.
The following parameters allow you to enable/disable the sending of MAC
address and line number to the call server:
• sip send mac
• sip send line
These parameters are disabled by default. The parameters are configurable via the
configuration files or the Aastra Web UI.
