•Dial Plan Commands, page 5-53

•Dial Plan Rules, page 5-54

•Dial Plan Examples, page 5-58

The following list contains commands that can be used to create you own dial plans:

•. —Wildcard, match any digit entered.

•- —Additional digits can be entered. This command can be used only at the end of a dial plan rule (for example, 1408t5- is legal usage of the - command, but 1408t5-3... is illegal).

•[ ]—Range, which means to match any single digit in the list. Use an underscore ( _ ) to indicate a range of digits. For example, [135] matches the digits 1, 3, and 5. Also, [1_5] matches the digits 1, 2, 3, 4 and 5. The pound key (#) and asterisk (*) are not allowed in the Range command. Also, the Repeat (rn) command does not apply to range, and range cannot include the Subrule matching command.

•(subrule0 subrule1 ...subruleN)—Subrule matching. Using the ( ) and operators allows you to specify multiple subrules within a dial plan rule so that a subrule match is reached if the entered digits fit one of the subrules. This can be used to reduce the length of the desired dial plan rule by concatenating the group of the subrules with the common rule.

For example, a dial plan rule of (1900180017..)555.r3 or three dial plan rules of 1900555.r31800555.r317..555.r3 are equivalent. A match is reached if 11 digits are entered and the first three digits are either 1900, 1800, or 17..., and the fifth, sixth, and seventh digits are all 5.

•>#—Defines the # character as a termination character. When the termination character is entered, the dial string is automatically sent. The termination character can be entered only after at least one user-entered digit matches a dial plan rule. Alternatively, the command >* can be used to define * as the termination character.

•tn— Defines the timeout value n, in the unit of seconds, for the interdigit timer. Valid values are 0-9 and a-z, where a-z indicates a range of 10 to 35.

•rn—Repeat the last pattern n times, where n is 0-9 or a-z. The values a-z indicate a range of 10 to 26. Use the repeat modifier to specify more rules in less space.

Note The commands ># and tn are modifiers, not patterns, and are ignored by the rn command.

•—Used to separate multiple dial plan rules.

•^—Logical not. Match any character except the character immediately following the ^ command. The ^ command can also be used as a negation instruction before the range or subrule matching commands.

•S—Seize rule matching. If a dial plan rule matches the sequence of digits entered by the user to this point, and the modifier S is the next command in the dial plan rule, all other rules are negated for the remainder of the call (for example, a dial plan beginning with *S will be the only one in effect if the user first enters the * key).

Note All rules apply in the order listed (whichever rule is completely matched first will immediately send the dial string).

ATA 188, ATA 186 specifications

The Cisco Systems ATA 186, or Analog Telephone Adapter, revolutionized the way traditional telephony interacted with Voice over Internet Protocol (VoIP) systems. Designed primarily for home and small office use, the ATA 186 allows users to connect standard analog phones and fax machines to a network, enabling them to take advantage of the benefits of VoIP technology.

One of the defining features of the ATA 186 is its dual port architecture. It includes two FXS ports, allowing users to connect up to two analog telephones. This functionality means that multiple devices can leverage VoIP services simultaneously without the need for separate adapters for each phone. The flexibility of the ATA 186 helps streamline the user experience, facilitating voice communication over an IP network while ensuring users can still use their existing phone equipment.

The ATA 186 employs various technologies to maintain high-quality voice calls. It supports standard voice codecs such as G.711 and G.729, which ensure efficient bandwidth usage while preserving call clarity. The adaptive jitter buffer technology further enhances call quality, compensating for network variations and minimizing latency, which is crucial for clear and uninterrupted conversations.

Additionally, the ATA 186 provides users with advanced calling features that were traditionally available only on PBX systems. These features include caller ID, call waiting, and voicemail functionality, integrating seamlessly with typical telephony services. The device also supports T.38 fax relay, allowing users to send and receive faxes over the internet, thus addressing the needs of environments where fax communication remains essential.

The security of VoIP conversations is also a priority for the ATA 186. It employs encryption protocols such as Secure Real-time Transport Protocol (SRTP) and Transport Layer Security (TLS), ensuring that voice data is securely transmitted across the network. This focus on security helps protect sensitive information transmitted during calls.

Installation and configuration of the ATA 186 is streamlined, with an intuitive web-based interface that simplifies the setup process. This accessibility makes it suitable for users with varying levels of technical expertise, as frequently required adjustments, such as network configurations and firmware updates, can be easily managed.

In conclusion, the Cisco Systems ATA 186 stands out as a versatile and robust solution for users looking to integrate analog phones into a VoIP environment. With its dual port capabilities, high-quality voice codecs, advanced call features, and security measures, it offers a compelling choice for both residential and commercial users seeking seamless telephony integration. As technology evolves, devices like the ATA 186 remain cornerstones in bridging traditional telephony with modern communication systems.
