Chapter 3 Configuring the Cisco ATA for MGCP

Configuring the Cisco ATA Using a TFTP Server

Configuring the Cisco ATA Using a TFTP Server

The TFTP method of configuration is useful when you have many Cisco ATA because you can use a TFTP server for remote, batch configuration of Cisco ATAs. A TFTP server can host one unique configuration file for each Cisco ATA.

This section contains the following topics:

•Setting Up the TFTP Server with Cisco ATA Software, page 3-8

•Configurable Features and Related Parameters, page 3-8

•Creating Unique and Common Cisco ATA Configuration Files, page 3-9

•atadefault.cfg Configuration File, page 3-17

•Configuring the Cisco ATA to Obtain its Configuration File from the TFTP Server, page 3-18

Setting Up the TFTP Server with Cisco ATA Software

This section provides the procedure for the Cisco ATA administrator to obtain the correct Cisco ATA software and set up the TFTP server with this software.

Procedure

Step 1 If you are a registered CCO user. go to the following URL:

http://www.cisco.com/cgi-bin/tablebuild.pl/ata186

Step 2 Download the zip file that contains the software for the applicable release and signaling image you are using. The contents of each file are described next to the file name. Save the zip file onto a floppy disc.

Note The file that contains the protocol signaling image has an extension of .zup.

Step 3 Extract the signaling files onto the TFTP server. This should be the same TFTP server that will contain the binary Cisco ATA configuration file that you create (either ata<macaddress> with a possible file extension or atadefault.cfg). For information about possible configuration file names, see the “Configuration Files that the cfgfmt Tool Creates” section on page 3-13.

Configurable Features and Related Parameters

For a list of all required MGCP parameters, see the “Required Parameters” section on page 4-2. These parameters must be properly configured for the Cisco ATA to work.

For descriptions of important Cisco ATA MGCP services that you can configure, and references to their configuration parameters, see the “Important Basic MGCP Services” section on page 4-2and the “Additional MGCP Services” section on page 4-3.

Table 4-1 on page 4-5lists, in alphabetical order, various features that you can configure for the Cisco ATA. Table 4-1 on page 4-5also includes links to the related parameter that allows you to configure each of these features. Each link takes you to a detailed description of the parameter that includes its default values.

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.
