Allowed and Denied Lists
Allowed and Denied Lists are used to restrict dialing of long-distance and international numbers. A number is blocked if its prefix matches any entry in the Denied Lists. On the other hand, a number is allowed to go through if it matched with any entry of Allowed List. This provides flexibility of allowing only specific numbers while blocking all others.

Automatic Call Distribution
Eternity offers different schemes to select destination port for an incoming call. They are First Free and Round Robin.

Automatic Number Translation
The Eternity modifies the dialed number or part thereof so that it matches with the numbering plan of the destination networks like PSTN, GSM/CDMA and VoIP. For example on VoIP network, if a user dials the number (223344) to call www.abc.com, the Eternity adds appropriate access code (*777) specified by the ITSP and dials out the number - *777223344 instead of 223344. In the case of GSM/CDMA network, when a user dials the local number, Eternity adds respective country-area codes as an appropriate prefix.
