Remote Endpoint Control and NAT
A service provider can remotely modify the configuration parameters in an IP
Telephony device after the unit has been deployed to the customer premises and
upgrade the firmware.
The IP Telephony device accesses the Internet through a router by using network
address translation (NAT). For enhanced security, the router might attempt to block
unauthorized incoming packets by implementing symmetric NAT (a packet filtering
strategy that severely restricts the packets that are allowed to enter the protected
network from the Internet).
Communication Encryption
The configuration parameters communicated to the IP Telephony device can
contain authorization codes or other information that protect the system from
unauthorized access. It is in the service provider's interest to prevent unauthorized
activity by the customer, and it is in the customer's interest to prevent the
unauthorized use of the account. The service provider can encrypt the
configuration profile communication between the provisioning server and the IP
Telephony device, in addition to restricting access to the administration web
server.
