Avaya Aura® Session Manager communicates with the Avaya Push Notification provider cloud service using HTTPS. To use the Avaya Push Notification provider, your enterprise network firewall and the HTTP proxy server must allow outbound HTTPS connections to the Avaya Push Notification provider address, which is pnp.avaya.com:443.

For applications other than Avaya Workplace Client, you must use a third-party provider. The firewall and the HTTP proxy of your enterprise must allow outbound HTTPS connections to this push notification provider.

For mobile devices running in your enterprise network, push notifications rely on connectivity between mobile devices and the Push Notification service network. For more information about port configuration required to receive push notifications, see the respective push notification service website.
