When configuring a Reverse Proxy for the Avaya Aura® Web Gateway (AAWG) in the Avaya Session Border Controller for Enterprise (ASBCE), the Server Address field is used to specify the IP address or FQDN and port of the AAWG server. The port used in this field shouldmatch the listen port on the AAWG server that is used for all WebRTC call signalling. The default listen port on the AAWG server is 8444, which is also used by default in the Server Address field of the ASBCE Reverse Proxy configuration. The Reverse Proxy allows external clients to access the AAWG server securely and transparently through the ASBCE

 tracePS is a CLI tool that allows you to capture and analyze XMPP traffic between Avaya Aura® Presence Services and other XMPP servers or clients. You can use this tool to troubleshoot issues related to presence, instant messaging, federation, or integration with third-party applications. You can also use this tool to generate reports on XMPP traffic statistics, such as message count, message size, message type, and message direction

When configuring the Avaya Call Park and Page snap-in, the Call Park Extension Group attribute is used to specify the extensions that can be used to park calls. The format of the Call Park Extension Group attribute is as follows:

():,,…

The location ID is a numeric value that identifies the location where the Call Park and Page snap-in is deployed. The number of digits is the number of digits in each extension. The extensions are the actual extensions that can be used to park calls. For example, 3(1):4000,4001,4002 means that the Call Park and Page snap-in is deployed in location 3, each extension has one digit, and the extensions are 4000, 4001, and 40021

To access the TSAPI Test from the Application Enablement Services (AES) menu, you need to select Utilities. The TSAPI Test is a basic application for making a call using TSAPI, which is a high-level API for CTI applications based on CSTA I standard. TSAPI allows access to the third party call control capabilities of CM through AES. The TSAPI Test application can be used to verify that the TSAPI client is correctly installed and working on AES. If the TSAPI Test application fails to make the call, an error message is provided to aid in troubleshooting the cause of the failure. To access the TSAPI Test from the AES menu, you need to follow these steps:

• Log in to the web interface of AES using your username and password.
• Click on Utilities on the left side menu.
• Click on TSAPI Test under Utilities.
• Enter the parameters for making a call, such as device name, destination number, user ID, and password.
• Click on Make Call.

The Avaya Breeze® cluster type determines the functionality and features of the Avaya Breeze® platform. There are four cluster types: General Purpose, IM_Presence, Core Platform, and Presence Services. The Core Platform cluster type is required to install the Avaya Aura® Presence Services snap-in, as it provides the basic services and components for the Avaya Breeze® platform, such as security, clustering, management, and routing. The other cluster types are either deprecated or not compatible with the Presence Services snap-in.

An H.248 signaling link connects the Internet Friendly (Edge) Gateway to Avaya Communication Manager (CM) by tunneling H.248 messages using TCP port 2944 and securing them using TLS. H.248 is a protocol that defines how media gateway controllers control media gateways for supporting multimedia streams across different networks, such as IP networks and PSTN networks. An H.248 signaling link is a logical connection between an H.248 controller and an H.248 gateway that allows exchanging H.248 messages for controlling media streams. In an Internet Friendly (Edge) Gateway scenario, CM acts as an H.248 controller and ASBCE DBE acts as an H.248 gateway. To connect an H.248 signaling link between CM and ASBCE DBE, these steps are performed:

• CM initiates a TCP connection to ASBCE DBE using port 2944, which is reserved for H.248 over TLS.
• CM and ASBCE DBE negotiate TLS parameters and exchange certificates for mutual authentication and encryption.
• CM and ASBCE DBE establish a secure TLS session over TCP port 2944.
• CM and ASBCE DBE exchange H.248 messages over TLS session for controlling media streams.

The output from the show mgc command (issued on a G430/G450 Gateway CLI) can indicate whether the G430/G450 is operating as an Internet Friendly (Edge) Gateway or an Enterprise Gateway. An Internet Friendly (Edge) Gateway is a device that provides secure and reliable connectivity between endpoints on different networks, such as the public internet and a private enterprise network. An Enterprise Gateway is a device that provides connectivity between endpoints on the same network, such as a LAN or a WAN. The show mgc command displays information about the Media Gateway Controller (MGC), which is the entity that controls the media gateway functions of the G430/G450, such as call processing, routing, and signaling. The MGC can be an Avaya Communication Manager (CM) server or an Avaya Session Border Controller for Enterprise (ASBCE) server. The output from the show mgc command includes these fields:

• Management Link Mode: This field indicates how the G430/G450 communicates with the MGC for management purposes, such as configuration, monitoring, and troubleshooting. The possible values are Direct or Tunnelled. Direct means that the G430/G450 communicates with the MGC using a direct IP connection over TCP port 5022. Tunnelled means that the G430/G450 communicates with the MGC using a tunnel over TCP port 2944 and secured using TLS. This mode is used when the G430/G450 operates as an Internet Friendly (Edge) Gateway and communicates with ASBCE as the MGC.
• H.248 Link Mode: This field indicates how the G430/G450 communicates with the MGC for media gateway control purposes, such as controlling media streams, allocating resources, and creating connections. The possible values areEGW or IFG. EGW means that the G430/G450 communicates with the MGC using H.248 protocol over UDP port 2944. This mode is used when the G430/G450 operates as an Enterprise Gateway and communicates with CM as the MGC. IFG means that the G430/G450 communicates with the MGC using H.248 protocol over TCP port 2944 and secured using TLS. This mode is used when the G430/G450 operates as an Internet Friendly (Edge) Gateway and communicates with ASBCE as the MGC.
• H.248 Link Status: This field indicates whether the H.248 link between the G430/G450 and the MGC is up or down, and whether it is encrypted or not. The possible values are UP/Encrypted, UP/Unencrypted, DOWN/Encrypted, or DOWN/Unencrypted. UP means that the H.248 link is established and functional. DOWN means that the H.248 link is not established or not functional. Encrypted means that the H.248 link is secured using TLS encryption. Unencrypted means that the H.248 link is not secured using TLS encryption.

Therefore, to determine whether the G430/G450 is operating as an Internet Friendly (Edge) Gateway or an Enterprise Gateway, you can look at these two fields in the output from the show mgc command:

• If the H.248 Link Mode displays IFG, it means that the G430/G450 is operating as an Internet Friendly (Edge) Gateway and communicating with ASBCE as the MGC using H.248 over TCP port 2944 and secured using TLS.
• If the H.248 Link Status displays UP/Encrypted, it means that the G430/G450 is operating as an Internet Friendly (Edge) Gateway and communicating with ASBCE as the MGC using a secure and functional H.248 link.

If the customer requires High Availability (HA) for the Avaya Session Border Controller for Enterprise (ASBCE), the minimum number of servers or virtual machines that are required is 2. High Availability (HA) is a feature that provides redundancy and fault tolerance for the ASBCE server by deploying two ASBCE servers in a pair, either in the same location or geographically dispersed. The two ASBCE servers act as a single logical entity and share a common configuration and license. One ASBCE server is designated as the active server and handles all traffic, while the other ASBCE server is designated as the standby server and monitors the status of the active server. If the active server fails or becomes unreachable, the standby server takes over and becomes the new active server, ensuring continuity ofservice. The two ASBCE servers synchronize their configuration and state information using a dedicated HA link between them

When installing the identity certificate and encryption key files on the Avaya Session Border Controller for Enterprise (ASBCE), you need to follow this rule: The filename of the identity certificate (.pem or .crt file) must be different from the filename of the encryption key (.key file). An identity certificate is a file that contains information about the identity and public key of an entity, such as a server or an endpoint. An encryption key is a file that contains information about the private key of an entity, which is used to encrypt and decrypt data. The identity certificate and encryption key files are obtained from a Certificate Authority (CA) or generated by yourself using tools such as OpenSSL. When installing these files on the ASBCE server, you need to make sure that they have different filenames, otherwise they will overwriteeach other and cause errors. For example, you can name them as sbce-cert.pem and sbce-key.key respectively.

A field engineer runs the Installation Wizard during the deployment of the Avaya Session Border Controller for Enterprise (ASBCE). The Installation Wizard is a tool that guides the engineer through the initial configuration of the ASBCE server, such as setting the hostname, IP addresses, passwords, and time zone. During the Installation Wizard, one of the steps is to configure a Domain Name System (DNS) server address for the ASBCE server. A DNS server is a server that resolves domain names into IP addresses and vice versa. The ASBCE server needs a DNS server address to communicate with other entities that use domain names, such as SIP servers or endpoints. The Installation Wizard allows configuring both a Primary DNS server address and a Secondary DNS server address for redundancy purposes. However, only a Primary DNS server address is mandatory, while a Secondary DNS server address is optional. Therefore, the statement that is true about configuring a DNS server address during the Installation Wizard is that a Primary DNS server address needs to be configured.

The statement that is true about the Application Enablement Services (AES) certificate management is that AES is shipped with a default certificate which is valid for one year, and a customer-provided server identity certificate must be installed before the default certificate expires. A server identity certificate is a file that contains information about the identity and public key of a server, such as AES. A server identity certificate is used to authenticate the server to other entities that communicate with it using HTTPS or SIP over TLS. A server identity certificate is signed by a Certificate Authority (CA), which is an entity that issues and verifies certificates. AES uses certificates for various purposes, such as securing web access, enabling HTTPS-based APIs, encrypting SIP signaling, and supporting mutual authentication with endpoints or servers. AES comes with a default self-signed certificate that can be used for testing or demonstration purposes. The default certificate is valid for one year from the date of installation. After one year, the default certificate expires and needs to be replaced with a valid customer-provided certificate from a trusted CA. To install a customer-provided certificate on AES, you need to use tools such as OpenSSL or Keytool to generate a Certificate Signing Request (CSR), submit it to a CA, obtain a signed certificate from the CA, and upload it to AES using the web interface or CLI.

If the Avaya Session Border Controller for Enterprise (ASBCE) does not trust the Certificate Authority (CA) that signed the WebLM server identity certificate, you can use the sbceconfigurator.py fix-weblm-cert command issued from the EMS CLI to fix the trust issue. The WebLM server is a web-based licensing application that manages licenses for various Avaya products, such as Communication Manager, Session Manager, Presence Services, or Breeze Platform. The WebLM server uses an identity certificate to authenticate itself to other entities that communicate with it using HTTPS or REST APIs. The identity certificate is signed by a CA, which is an entity that issues and verifies certificates. The ASBCE server needs to trust the CA that signed the WebLM server identity certificate in order to communicate with it securely and obtain licenses from it. If the ASBCE server does not trust the CA, you can use the sbceconfigurator.py fix-weblm-cert command to install the CA certificate on the ASBCE server and establish trust with it. The sbceconfigurator.py tool is a Python script that runs on the EMS component of the ASBCE server and performs various configuration tasks. The EMS component is responsible for managing and monitoring the ASBCE server. You can access the EMS CLI using SSH or Telnet and run the sbceconfigurator.py tool from there.

To associate the Avaya Call Park and Page snap-in to an Avaya Workplace Client, you need to perform the following key configuration steps:

• Add a Service Profile: A Service Profile is a set of parameters that defines the features and capabilities of a user or device in System Manager. You need to create a Service Profile for the Call Park and Page snap-in, under Users > User Management > Service Profiles. In the Service Profile, you need to specify the name, type, domain, and SIP Entity of the Call Park and Page snap-in. You also need to enable the Call Park feature and configure the Call Park activation and deactivation feature codes1
• Configure a Call Park activation and deactivation feature code: A feature code is a numeric sequence that activates or deactivates a specific feature on Communication Manager. You need to configure a Call Park activation and deactivation feature code on Communication Manager, using the change feature-access-codes command. The Call Park activation feature code allows a user to park a call on a specified extension, while the Call Park deactivation feature code allows a user to retrieve a parked call from any extension2

When deploying the Avaya Aura® Presence Services on Avaya Breeze®, you can check the status of the Presence Services snap-in in System Manager, under Elements > Avaya Breeze> Service Management > Services. The status indicates the state of the snap-in on the Avaya Breeze® cluster. The status Active means that the snap-in is running and ready to support Presence and IM. The other statuses are either intermediate or error states that indicate that the snap-in is not fully functional or operational.
