IXC Softswitch. Functional Characteristics

IXC VoIp Softswitch can be implemented in three possible configurations:

• Standalone softswitch;
  
• Linear cluster;
  
• Starlike cluster.
  

Features:

• Prepaid service using authorization by prefix (IXCPHONE);
  
• Authorization and routing of incoming traffic depending on IP and prefix simultaneously (that is not allowed by Cisco);
  
• Online active calls viewing;
  
• Traffic monitoring using statistical characteristics like call duration, success call ratio, traffic values;
  
• Quality of connection based on analysis of RTP session between terminal devices;
  
• Different detailed elaboration of statistics;
  
• Accounting of cross traffic flow between companies;
  
• Handy generation of tariffs and possibility of calls cost converting if tariff changes had place;
  
• Handly interaction with Gatekeepers;
  
• Four-stage system of traffic flow routing including Least Cost routing;
  
• Generation of reports for CDR checks;
  
• View of routing tables both for a chosen customer, and for all customers together;
  
• Handy system of problematic destinations closing;
  
• Work with deposit customers, possibility of calls breaking when balance is empty;
  
• Work with time-depending tariffs;
  
• Switching h323 and SIP calls.
  

Deal with deposit customers and break calls after the money on deposit runs out you can only with IXC Financial Tools.
