1. Allow registration for Account

The Allow Registration function in the Account menu allows you to perform Authentication based on VoIP Login and VoIP Password parameters using the SIP secure digest authentication method. If the field is unchecked, it disables registration and SIP secure digest authentication, but it does not disable Authentication based on the Authentication Rules associated with each account.


2. Authenticate the call by Incoming CLI/ANI

Account Lookup by "Incoming CLI/ANI" works only if it is setup in Accounts --> Account XXXX --> Authentication Rules

3. Two Way Callback

Feature available only when the Web Callback module is purchased.

This feature connects two destinations together from the Account's self-care interface.

Login as Account and access Callback under the Services section.


Note. Web-callback module must be installed.

4. Allow Free On-Net Calls

By default, the Softswitch rejects the free-of-charge On-Net calls when either the Account's or sub customers balance is below zero. 

Starting from 5.2 a new option called "Allow Free On-Net Calls" was added to the Advanced Parameters of Account preferences and to the Calling Features section of Account Class.

Selecting the checkbox allows you to change the behavior and pass the free On-Net calls regardless of the Account's balance.  The option can be altered via xmlapi and our upload resource.

The feature was partially backported to 5.0 and 5.1 versions but full support is only available from 5.2.
