Routing calls to a station and forwarding unanswered calls to voice mail
EXAMPLE 1:
5300, cfwd=vm25300
An incoming call through this line interface causes station 5300 to ring. If there
is no answer, the call is forwarded to the voice mail server on line interface 2,
mailbox number 5300. The time interval is determined by the value
Cfwd No
Ans Delay
field, which is located below the
Contact List
field on the
Voice >
Line
page. The default value is 20 seconds.
EXAMPLE 2:
4085550122:5001|4085550123:5000,cfwd=aa
An incoming call to 408-555-0122 causes station 5001 to ring. An incoming call
to 408-555-0123 causes station 5000 to ring. If station 5000 does not answer
its call, the call is forwarded to the Auto Attendant. The time interval is
determined by the value
Cfwd No Ans Delay
field, which is located below the
Contact List
field. The default value is 20 seconds.

Routing a call with a hunt rule
EXAMPLE:
530?,hunt=ra;10;2,cfwd=vm25404
An incoming call through this line interface causes one station in the group
5300 through 5309 to ring. The station is chosen randomly (
ra
). After 10
seconds, if the call is unanswered, then another station is chosen randomly
from the remaining stations. The system cycles through the list two times. If the
call is unanswered, it is forwarded to the voice mail server on line interface 2,
mailbox 5404.
NOTE
A hunt rule in the contact list applies only to calls on the selected line
interface. You also can create hunt groups that apply to all lines. For more
information and additional examples of syntax that can be used in a hunt rule
in the Contact List, see
“Managing Inbound Calls with Hunt Groups,” on
page 92

Supporting Multiple DID Numbers Per Line Interface
An ITSP can provide a block of DID numbers, for example with a main number of
4085553000, and additional DID numbers from 4085553001–4084443009. The
ITSP can identify the local client stations to which an external incoming call should
be routed. Linksys recommends including this information in the TO header of the
incoming INVITE while the request-URI is addressed to the line interface user-id. In
the INVITE, the ITSP indicates the DID number in the TO header user-id field.
