  • This feature works only when the phone is idle: i.e, there is no active call
    If one is in speech with someone, and another call arrives, Auto-Answer will not function
    The Second call will be treated as Call Waiting and a Call Waiting Tone Will be heard and Ringer LED Will blink
  • UDP: A Network Protocol for Transmitting Data that does not require acknowledgement from the recipient for
    the Data that is sent, hence comes under the category of connectionless protocol
  • Security Enhancement: Implementing dynamic NAT automatically creates a firewall between your internal network and outside networks, or between your internal network and the Internet. NAT only allows connections that originate inside the stub domain. Essentially, this means that a computer on an external network cannot connect to your computer unless your computer has initiated the contact. You can browse the Internet and connect to a site, and even download a file; but somebody else cannot latch onto your IP address and use it to connect to a port on your computer.
  • NAT Router replaces source IP (Private IP) with its Own public IP before passing the traffic to the destination on Internet
    When a response is received, NAT Router searches its translation tables for Original Source Address from which device has started the Connection and then passes the response to that Device
    NAT is also called as ‘IP Masquerading’
    Traffic Passing through NAT is called as ‘NAT Traversal’
