Dial Plan Parameters

Dial Plan Example 2

The following dial plans:

.t7>#

t4-9111t7>#

..........t1-0t4>#.t7-

or

.t7>#r6t4-9111t7>#.r9t1-0t4>#.t7-

consist of the following rules:

•.t7>#r6t4-—You must enter at least one digit. After the first digit is entered and matched by the dial plan, the timeout before an automatic send is seven seconds, and the terminating character # can be entered at any time to manually send the dial string. After seven digits are entered, the timeout before an automatic send changes to two seconds. The - symbol at the end of the rule allows further digits to be entered until the dial string is sent by the timeout or the user entering the # character.

•911—If the dial string 911 is entered, send this string immediately.

•1t7>#.r9t1—If the first digit entered is 1, the timeout before an automatic send is seven seconds, and the terminating character # can be entered at any time to manually send the dial string. After the 11th digit is entered, the timeout before an automatic send changes to one second. The user can enter more digits until the dial string is sent by the timeout or by the user entering the # character.

•0t4>#.t7—If the first digit entered is 0, the timeout before an automatic send is four seconds, and the terminating character # can be entered at any time to manually send the dial string. After the second digit is entered, the timeout before an automatic send changes to seven seconds. The user can enter more digits until the dial string is sent by the timeout or by the user entering the # character.

Dial Plan Example 3

The following dial plan:

R1408([2_9].r5[2_9].r6)R9^(911.r4)X(19001888)F011

consists of the following rules:

•R1408([2_9].r5[2_9].r6)—The prefix 1408 will be added to any call numbers with seven or eight digits where the leading digit is in the range of 2 to 9. For example, 5551234 will become 14085551234, but 555123 does not match this rule.

•R9^(911.r4)— The prefix 9 will added to any numbers except 911 and five-digit numbers. For example, 911 will still be 911, and 51234 will still be 51234.

•X(19001888)— There will be no calls or call forwarding to numbers beginning with 1900 or 1888.

•F011—There will be no call forwarding to numbers beginning with 011.

In Dial Plan Example 3, there are two ‘R’ rules, so the first matched rule is triggered. Therefore, 5551234 becomes 14085551234. However, 555123 will then become 9555123 because it matches the second rule.

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.
