How To Register An Ata To Avaya Site Administrator

Set up to Install the ATA 191 on Your Network

Interactions with Other Cisco Unified IP Communications Products

The ATA 191 enables you lot to communicate using vox over a information network. To provide this capability, the ATA 191 depends upon and interacts with several other central Cisco Unified IP Telephony and Network components, including Cisco Unified Communications Manager, DNS and DHCP servers, TFTP servers, media resource, and so on.

To function in the IP telephony network, the ATA 191 must be connected to a networking device, such every bit a Cisco Goad switch. You must also annals the ATA 191 with a Cisco Unified Communications Director arrangement before you lot tin can transport and receive calls.

Interaction with Cisco Unified Communications Managing director

Cisco Unified Communciations Managing director is an open industry-standard telephone call process system. Cisco Unified Communications Managing director software sets upwardly and tears downwardly calls between analog phones that are connected to the ATA, and thus integrates traditional PBX functionality with the corporate IP network. Cisco Unified Communications Director manages the components of the IP telephony arrangement: the phones, the access gateways, and the resources necessary for features such as call conferencing and route planning. Cisco Unified Communications Manager also provides:

Firmware for devices
Authentication and encryption (if configured for the telephony system)
Configuration and CTL files via the TFTP service
Phone registration
Call preservation, and so that a media session continues if signaling is lost betwixt the primary Communications Manager

For information about configuring Cisco Unified Communications Managing director to piece of work with the IP devices described in this chapter, see Administration Guide for Cisco Unified Communications Manager and IM and Presence Service, System Configuration Guide for Cisco Unified Communications Manager, and Security Guide for Cisco Unified Communications Director.

Power Guidelines

The ATA is powered with external power. External power is provided through a separate power supply.

The following power type and guideline applies to external ability for the ATA:

Power Type—External power (provided through the Universal Ac external power supply).
Guidelines—The ATA uses the Universal AC power supply 100/240V.

Power Outage

Your accessibility to emergency service through the phone depends the phone being powered. If in that location is an interruption in the power supply, Service and Emergency Calling Service dialing will not function until power is restored. In the instance of a power failure or disruption, you may need to reset or reconfigure equipment before using the Service or Emergency Calling Service dialing.

Phone Configuration Files

Configuration files for a phone are stored on the TFTP server and define parameters for connecting to Cisco Unified Communications Manager. When yous make a change in Cisco Unified Communications Manager that requires the ATA 191 line to be reset, the telephone configuration file is automatically updated. If a organisation reset or restart is required, both lines must reset or restart at the aforementioned fourth dimension.

Configuration files also contain data about which paradigm load the ATA 191 should be running. If this image load differs from the one currently loaded on an ATA 191, the phone contacts the TFTP server to request the required load files. These files are digitally signed to ensure the authenticity of the file source.

If the device security mode in the configuration file is set to Authenticated and the CTL file on the ATA 191 has a valid certificate for Cisco Unified Communications Manager, the phone establishes a TLS connection to Cisco Unified Communications Manager. Otherwise, the ATA 191 establishes a TCP/UDP connection. Y'all can become to on the ATA 191 spider web GUI, where the SIP Ship should represent to the transport type in the Phone Security Profile in Cisco Unified Communications Manager.

If you lot configure security-related settings in Cisco Unified Communications Manager Administration, the phone configuration file contains sensitive information. To ensure the privacy of a configuration file, configure it for encryption. For detailed information, see the "Encrypted Phone Configuration Setup" chapter of the Security Guide for Cisco Unified Communications Director at: https://www.cisco.com/c/en/usa/support/unified-communications/unified-communications-manager-callmanager/products-maintenance-guides-list.html.

If the ATA 191 has registered before, the ATA 191 accesses the configuration file named ATA<mac_address>.cnf.xml, where mac_address is the MAC address of the phone. If the ATA 191 cannot access that configuration file, so it accesses the default XMLDefault.cnf.xml configuration file.

If autoregistration is not enabled and you did not add the ATA 191 to the Cisco Unified Communications Director database, the ATA 191 does non attempt to register with Cisco Unified Communications Managing director.

For the ATA 191, the TFTP server generates these SIP configuration files:

SIP IP Telephone:
- For unsigned and unencrypted files—ATA<mac>.cnf.xml
- For signed files—ATA<mac>.cnf.xml.sgn
- For signed and encrypted files—ATA<mac>.cnf.xml.enc.sgn

The filenames are derived from the MAC Address in the Phone Configuration window of Cisco Unified Communications Manager Assistants. The MAC address uniquely identifies the phone. For more than information, come across the Assistants Guide for Cisco Unified Communications Manager and IM and Presence Service.

For more information about how the phone interacts with the TFTP server, encounter the "Configure TFTP Servers" chapter of the System Configuration Guide for Cisco Unified Communications Manager at: https://www.cisco.com/c/en/us/support/unified-communications/unified-communications-managing director-callmanager/products-installation-and-configuration-guides-list.html

ATA 191 Startup Procedure

When the ATA 191 connects to the VoIP network, it goes through a standard startup procedure. Depending on your specific network configuration, non all these process steps may occur on your ATA.

Table i. ATA 191 Startup Process
Task		Related Topics
ane	Obtaining ability. The ATA 191 uses external ability.	See Power Guidelines .
2	Loading the Stored Image. The Cisco ATA 191 has nonvolatile wink memory in which it stores firmware images and user-defined preferences. At startup, the ATA 191 runs a bootstrap loader that loads an ATA 191 prototype stored in wink memory. Using this image, the ATA 191 initializes its software and hardware.
3	Obtaining an IP Address. If the Cisco ATA 191 is using DHCP to obtain an IP address, the device queries the DHCP server to obtain one. If you are not using DHCP in your network, assign static IP addresses to each device locally.
4	Requesting the CTL file. The TFTP server stores the CTL file. This file contains the certificates necessary for establishing a secure connection between the device and Cisco Unified Communications Managing director.	See the "Cisco CTL Client Setup" affiliate of the Security Guide for Cisco Unified Communications Manager at: https://world wide web.cisco.com/c/en/us/support/unified-communications/unified-communications-manager-callmanager/products-maintenance-guides-listing.html
v	Requesting the Configuration File. The TFTP server has configuration files, which define parameters for connecting to Cisco Unified Communications Manager and other information for the ATA 191.	See Telephone Configuration Files .
6	Contacting Cisco Unified Communications Manager. The configuration file defines how the ATA 191 communicates with Cisco Unified Communications Managing director and provides a device with its load ID. After obtaining the file from the TFTP server, the device attempts to make a connection to the highest priority Cisco Unified Communications Manager on the list. If the device is configured for secure signaling (encrypted or authenticated), and the Cisco Unified Communications Manager is set to Mixed (security) style, the device makes a TLS connection. Otherwise, it makes a nonsecure TCP/UDP connection.	Run across Phone Configuration Files.

Start upwardly Procedure with Standby Image

The ATA 191 has ii images or partitions in permanent storage. The second epitome allows the device to recover if the initial image is corrupted.

Printing the PRT button when the power is on, and you lot switch to the standby partition. Startup is similar to the normal procedure, except that the LED for Phone 2 flashes bister indicating that the second partition is being used.

Improver of the ATA 191 to the Cisco Unified CM Database

Earlier you install the ATA 191, choose a method for calculation the devices to the Cisco Unified Communications Manager database.

The following table provides an overview of these methods for adding the ATA 191 to the Cisco Unified Communications Director database.

Table two. Add the ATA to the Cisco Unified Communications Manager Database
Method	Requires MAC Accost?	Notes
Autoregistration	No	Results in automatic assignment of directory numbers. Not bachelor when mixed style is enabled.
Using the Cisco Unified Communications Manager Administration	Yep	Requires phones to be added individually.

Add-on with Autoregistration

Past enabling autoregistration before you brainstorm installing the ATA 191, you can:

Automatically add devices without start gathering MAC addresses from the ATA 191.
Automatically add an ATA 191 to the Cisco Unified Communications Manager database when you physically connect the phone to your IP telephony network. During autoregistration, Cisco Unified Communications Manager assigns the next bachelor sequential directory number to the phone.
To change any settings, apace enter devices into the Cisco Unified Communications Managing director database and modify settings, such as directory numbers, from Cisco Unified Communications Director.
Move autoregistered devices to new locations and assign them to different device pools without affecting their directory numbers.

Note

Back up exists for autoregistration for several devices in the Unified CM at the aforementioned time.

Autoregistration is disabled past default. Sometimes, you may not want to employ autoregistration. For case, if y'all want to assign a specific directory number to the telephone or if you plan to employ secure connection with Cisco Unified Communications Managing director. For information well-nigh enabling autoregistration, see the Enabling Auto-Registration in the Cisco Unified Communications Manager Administration Guide.

Annotation

For mixed style, autoregistration is automatically disabled and cannot exist changed. For nonsecure mode, autoregistration is disabled by default merely can be enabled manually.

Addition with Cisco Unified Communications Director Administration

Yous can add the ATA 191 individually to the Cisco Unified Communications Managing director database using Cisco Unified Communications Manager Administration. To practice so, start obtain the MAC accost for each device.

Subsequently yous have collected MAC addresses, in Cisco Unified Communications Managing director Administration, choose Device > Phone and click Add New to begin.

Note

The ATA 191 has two FXS ports, and each port has its ain MAC address. The start ATA 191 port uses the MAC address and the second ATA 191 port uses the shifted MAC address (example, AABBCCDDEEFF to BBCCDDEEFF01). You can add ii devices (either an analog phone or a fax machine) from the Unified CM administration page.

For complete instructions and conceptual information almost Cisco Unified Communications Manager, run across the Cisco Unified Communications Manager Administration Guide and the Cisco Unified Communications Manager Organisation Guide.

Make up one's mind the MAC Address of the ATA

Procedure

Cull one of the following methods to determine the MAC accost:

Expect at the MAC label on the back of the ATA.
Go to on the web page of the device and bank check the MAC accost.
