Pabx Billing System & Hotel Management System 4.4

This is Award-Winning Call Accounting System and Hotel Management System. It is Free for small customer who has equal or less than 18 Extensions or Hotel with less than 6 Rooms.
No duplicate call record, we establish checking tool inside database which rejects any coming CDR which have the same Called Date and Time, Called Number and Calling Number. So, customer can re-import unlimited time the raw log file to try to get new CDR
Supports any call charge scheme and multiple call charge schemes (one per each telephone service provider). Service charge including surcharge and flat charge can be based on calling party or called party.
Customer can define multiple Discount packages and assign to relevant Calling Party/Extension, so that call from these Calling Party/Extension will have defined discounts.
Volume Discount by CallType. For example, Local Call has Volumne Discount, while International CallType has no Volumne Discount. Volumne Discount will be set on Telephone Rate Table, or in other word, it is a property of Telephone Rate Table. Volumne Discount is not set directly by Calling Party/Extension. But because we can have multiple Telephone Rate Tables, and be able to assign Telephone Rate Table to Calling Party/Extension, we can indirectly set Volume Discount for subscribers.
