An Incoming Call To The Main Number Is Answered By The Auto-Attendant, While Calls To The Other Nine Did Numbers Are Routed To Dedicated Private Extensions; Supporting Direct Inward Dialing To Phone Extensions - Linksys SPA9000 Administration Manual

Configuring Phone Lines and Calling Routing Behavior
An incoming call to the main number is answered by the Auto-Attendant, while calls to the
other nine DID numbers are routed to dedicated private extensions.

Supporting Direct Inward Dialing to Phone Extensions

Direct Inward Dialing allows the external users to dial directly any phone extension in the LVS
system, without passing through the Auto Attendant or the receptionist.
Before proceeding with the configuration you need to have the full correspondence between
the external (DID) number and the extension number.
DID number
408-555-5550
408-555-5551
408-555-5552
408-555-5553
408-555-5554
408-555-5650
NOTE:
• Direct Inward Dialing requires network support for SIP trunking DID.
• It is important that the DID number format match exactly the format of the number
signaled in the SIP trunk.
• Please check with your Service Provider to confirm the availability of this feature and the
correct DID number format, before proceeding with this configuration.

• Enter a plus (+) or a minus (-) before the extension number to achieve the desired results
for caller ID and call routing:
– The extension will be alerted when there is an incoming call to the DID
+ <Extn1>
number, and the DID number will be used as the local user-ID in outbound SIP
requests, along with the display-name of the extension.
