Chapter 7 Upgrading the Cisco ATA Signaling Image

Upgrading the Signaling Image Via Cisco CallManager

Upgrading the Signaling Image Via Cisco CallManager

This feature is supported in Cisco CallManager version 3.2 or later and is the Cisco-recommended method for SCCP. The following requirements must be met:

•XML support must be turned on in the Cisco ATA (default is on). XML support is configured with Bit 31 of the ConnectMode parameter (see the “ConnectMode” section on page 5-13).

•This procedure can only be performed by the Cisco CallManager administrator.

Obtain the latest signaling image from the Cisco web site. See the “Setting Up the TFTP Server with Cisco ATA Software” section on page 3-8for instructions on where to find the software on the Cisco web site and how to place the files onto the Cisco CallManager TFTP server. The image file has the extension of .zup.

This section contains procedures for two different scenarios:

•Procedure for Upgrading all Cisco ATAs at Once, page 7-2

•Procedure for Upgrading One Cisco ATA, page 7-3

Procedure for Upgrading all Cisco ATAs at Once

Step 1 Download the latest Cisco ATA release software for SCCP from the Cisco web site, and store the files on the Cisco CallManager TFTP server. For more information, see the “Setting Up the TFTP Server with Cisco ATA Software” section on page 3-8.

Step 2 Go to the main Cisco CallManager Administration screen.

Step 3 From the System pull-down menu, select Device Defaults. The Device Defaults screen appears.

Step 4 In the Device Type list, find the device type Cisco ATA 186. In the Load Information field next to the device type of Cisco ATA 186, enter the name of the signaling image (the signaling image has an extension of .zup, for example, ATA186-v2-15-ms-020812a.zup) to use for upgrading the Cisco ATAs.

Step 5 Press the Update button at the top of the Device Defaults screen.

Step 6 From the Device pull-down menu, select Phone. The Find and List Phones screen appears.

Step 7 In the area next to the Find button, enter the letters “ata”, then press Find. The Find and List Phones screen reappears, and now contains all the Cisco ATAs connected to your Cisco CallManager.

Step 8 Check the box to the left of the Device Name column (above all listed devices) to select all the Cisco ATAs shown.

Step 9 Click the Reset Selected button at the bottom of the Find and List Phones screen.

Step 10 The Reset Device pop-up window appears. Click Reset Device. The Reset Device popup window appears. Click Reset to complete the procedure.

Step 11 A confirmation box appears. Click OK.

The function button on each Cisco ATA blinks during its upgrade. Once the button stops blinking, the upgrade is complete and the device re-registers to the Cisco CallManager.

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.
