Configuring a Dial Plan Figure 3-5 Upload Ringtone Utility Chapter 3 Managing Linksys 900 Series IP Phones For input, you can use any .wav file less than eight seconds. Configuring a Dial Plan The 900 Series phone allows each line to be configured with a distinct dial plan. The dial plan specifies how to interpret digit sequences dialed by the user, and how to convert those sequences into an outbound dial string. The 900 Series phone syntax for the dial plan closely resembles the corresponding syntax specified by MGCP and MEGACO. Some extensions are added that are useful in an end-point. Dial Plan Digit Sequences The plans contain a series of digit sequences, separated by the | character. The collection of sequences is enclosed in parentheses. When a user dials a series of digits, each sequence in the dial plan is tested as a possible match. The matching sequences form a set of candidate digit sequences. As more digits are entered by the user, the set of candidates diminishes until only one or none are valid. Any one of a set of terminating events triggers the 900 Series phone to either accept the user-dialed sequence and transmit it to initiate a call, or else to reject it as invalid. The terminating events are as follows: • No candidate sequences remain-The number is rejected. • Only one candidate sequence remains, and it has been matched completely-The number is accepted and transmitted after any transformations indicated by the dial plan, unless the sequence is barred by the dial plan, in which case the number is rejected. • A timeout occurs-The digit sequence is accepted and transmitted as dialed if incomplete, or transformed as per the dial plan if complete. 3-22 Linksys 900 Series IP Phone Administrator Guide Document Version 3.0

Configuring a Dial Plan
The 900 Series phone allows each line to be configured with a distinct dial plan. The dial plan
specifies how to interpret digit sequences dialed by the user, and how to convert those
sequences into an outbound dial string.
The 900 Series phone syntax for the dial plan closely resembles the corresponding syntax
specified by MGCP and MEGACO. Some extensions are added that are useful in an end-point.
Dial Plan Digit Sequences
The plans contain a series of digit sequences, separated by the | character. The collection of
sequences is enclosed in parentheses.
When a user dials a series of digits, each sequence in the dial plan is tested as a possible match.
The matching sequences form a set of candidate digit sequences. As more digits are entered by
the user, the set of candidates diminishes until only one or none are valid.
Any one of a set of terminating events triggers the 900 Series phone to either accept the
user-dialed sequence and transmit it to initiate a call, or else to reject it as invalid. The
terminating events are as follows:
•
No candidate sequences remain—The number is rejected.
•
Only one candidate sequence remains, and it has been matched completely—The number is
accepted and transmitted after any transformations indicated by the dial plan, unless the sequence
is barred by the dial plan, in which case the number is rejected.
•
A timeout occurs—The digit sequence is accepted and transmitted as dialed if incomplete, or
transformed as per the dial plan if complete.
