Avaya Aura® MS only processes SIP traffic from trusted nodes, for example, proxies. Avaya Aura® MS rejects requests from nodes that are not trusted. All proxy servers and registrar servers that interact with Avaya Aura® MS must be trusted nodes.
Perform the following procedure to configure trusted nodes for each proxy server and registrar server:
Procedure
Navigate to EM > System Configuration > Signaling Protocols > SIP > Nodes and Routes.
In the Trusted Nodes section, click Add to add a new SIP trusted node.
On the Add SIP Trusted Node page, enter the address of the SIP node in the Host or Server Address field.
