• Outgoing Line
Specifies which outgoing line this IP phone uses for outgoing calls. The term
"outgoing line" refers to one of the 6 FXO ports that are located on the back
of the AastraLink device.
The default is Any. Alternatively, you can specify that this phone may only
use a specific outgoing line for its calls. This is useful if different FXO lines
have different originating CLID, and is usually used in combination with the
Configuration->Dialplan->Private Line feature so that incoming and
outgoing calls are routed using the same FXO line.
• Phone Type
Specifies the model of this Aastra IP phone. Select the applicable phone from
the list.
• MAC Address
Specifies the MAC Address assigned to this IP phone.
• SIP DID Number
Specifies the SIP Direct Inward Dialing (DID) number to this IP phone. A
DID number is an individual telephone number assigned to this phone that
allows an outside caller to dial directly from incoming SIP trunk calls to the
users extension, without having to route via the Operator or IVR menu
system.
