The VoIP Interface
The Voice-over-IP (VoIP) Interface routes over the Internet, all the outgoing and incoming calls made or received
by the extensions of the ETERNITY NENX and extensions of other System that are networked with the ETERNITY
NENX.
The VoIP Interface supports Session Initiation Protocol (SIP), the industry standard VoIP.
The VoIP Interface supports SIP Trunks and SIP Extensions.
With SIP Trunks users can make IP calls using the SIP Server of the Internet Telephony Service Providers (ITSPs).
The VoIP Module has an in-built Registrar Server that allows any SIP enabled device like a Wi-Fi mobile handset, a
PDA or an IP-Phone to be registered with it and function as the 'SIP Extension' of the ETERNITY NENX. The SIP
Extension users can make and receive calls to any extension user of the ETERNITY as well as any external
