Introduction

The Oracle® Enterprise Session Border Controller (ESBC) includes a Personal Profile Manager (PPM) proxy feature. PPM is a web service that runs as part of Avaya Aura Session Manager and Aura System Manager. Local and remote SIP clients may download configuration data from the PPM proxy using SOAP messages over HTTP or HTTPS, enabling soft keys to be customized and contact lists to be loaded. In enterprise networks, certain messages may refer to private IP addresses that are not routable from the remote clients. You can configure the ESBC as an application proxy in the for this traffic. This proxy can:

• Replace the "internal IP addresses" with the ESBC external SIP interface IP address
• Replace the "internal IP addresses" (Public) with a NAT address

Remote clients accessing the PPM proxy are authenticated by HTTP digest authentication, using their SIP credentials. The PPM proxy forwards such challenges and responses transparently to the PPM web service for which it is configured.

Additional ESBC configuration includes:

• Configure DoS rules to protect the proxy port as part of standard configurations
• Configure the PPM proxy for Transport Layer Security (TLS) to support HTTPS
