“Whitelist” Proxy Support for Sylantro Servers

To protect your IP phone network, you can configure a “whitelist” proxy feature

that screens incoming call requests received by Aastra IP phones. When this

feature is enabled, an IP phone accepts call requests from a trusted proxy server

only. The IP phone rejects any call requests from an untrusted proxy server.
