Chapter 8 Upgrading the Cisco ATA Signaling Image

Upgrading the Signaling Image Manually

•image_id is a unique 32-bit integer that differs with each upgrade. You can determine this 32-bit integer value by using the build date on the image file name and prepending it with "0x". For example, if the image_file_name is ata186-v2-14-020514a.kxz, then the build date is 020508a, and the image_id is 0x020508a).

•image_file_name is the firmware upgrade-image file name. The image_file_name format is: ata186-v{M}-{N}-{yymmdd}{a-f}{ext}

–- M is the major version number

–- N is the minor version number (always two digits)

–- yymmdd is a two-digit year, two-digit month, and two-digit day

–- a-fis the build letter (- yymmdd and a-ftogether form the build date of the image)

–- ext must be ".kxz" for upgrading from version 2.11 and below, and can be ".zup" for upgrading from version 2.12 and up for the Cisco ATA186, but it must be ".zup" for upgrading the Cisco ATA188.

Process

Whenever the Cisco ATA administrator stores a new signaling image (denoted by a change to the image_id), the Cisco ATA upgrades its firmware with the new image_file. To contact the TFTP server, the Cisco ATA uses the TFTP server IP address that is contained within the value of the upgradecode parameter.

Example

The upgradecode parameter value could be:

upgradecode:3,0x301,0x0400,0x0200,192.168.2.170,69,0x020723a,ata186-v2-15-020 723a.zup

This instructs the Cisco ATA to upgrade its firmware to ata186-v2-15-020723a.zup by downloading the ata186-v2-15-020723a.zup file from the TFTP server IP address of 192.168.2.170. This download occurs after the Cisco ATA downloads its configuration file that contains the directive from the upgradecode parameter. Also, the upgrade occurs only if the internally cached image_id in Cisco ATA is different from the value 0x020723a.

Upgrading the Signaling Image Manually

This section describes how to manually upgrade the Cisco ATA with the most recent signaling image. The executable file that you need is called ata186us.exe, and is bundled in the Cisco ATA release-software zip file.

ATA 188 specifications

The Cisco Systems ATA 188 is a versatile Analog Telephone Adapter designed to facilitate the integration of traditional telephone systems with Voice over Internet Protocol (VoIP) networks. This device has been key in bridging the gap between legacy telephony and modern IP-based communication, allowing users to leverage their existing analog phones while enjoying the benefits of digital connectivity.

One of the main features of the ATA 188 is its ability to connect regular analog phones to a VoIP network, enabling users to make and receive calls over the internet. This significantly reduces calling costs, especially for long-distance and international calls. The ATA 188 supports two phone lines, allowing simultaneous voice calls. This dual-line capability makes it a suitable choice for small businesses or home offices that require multiple lines without the need for extensive infrastructure.

The device is equipped with various technologies that enhance its functionality. It supports the Session Initiation Protocol (SIP) and H.323, making it compatible with a wide range of VoIP service providers. Additionally, the ATA 188 features Quality of Service (QoS) settings, which prioritize voice traffic over the internet, ensuring clear voice quality without interruptions or delays. This is essential for maintaining a professional communication experience, especially in business environments.

Another characteristic of the ATA 188 is its user-friendly configuration interface. It allows users to easily set up and manage their devices through a web-based portal. The configuration process is straightforward, with options to adjust settings such as codec selection, call features including call waiting, and call forwarding functionalities.

Security is also a priority for the ATA 188, as it provides robust protocols to protect call data. The device supports Secure Real-time Transport Protocol (SRTP) and Transport Layer Security (TLS) to encrypt voice traffic and manage signaling securely. This ensures that sensitive conversations remain confidential.

Overall, the Cisco Systems ATA 188 is a reliable and efficient solution for users looking to transition from traditional telephony to VoIP. Its dual-line capacity, compatibility with multiple VoIP standards, user-friendly configuration, and built-in security features make it a valuable asset for both personal and professional communication solutions. In an ever-evolving telecommunications landscape, the ATA 188 remains a relevant and practical choice for integrating legacy telephony with modern internet-based services.
