 # Does PKS do Least Cost Routing (LCR)?
 
 PKS cannot route calls based on the communication costs of SIP providers. This functionality, which is present in PyFreeBilling, has been removed, as it brings greater complexity, both in the scripting part and therefore in debugging, but also in terms of administration.

 # Connecting an IPBX to more than one operator
 
 In order to save money on subscriptions and telephone communications, it may be advisable to use different operators depending on the destinations or numbers required, particularly for international calls. P-KISS-SBC makes it possible to connect several operators to an IPBX and to route incoming calls to the IPBX, whatever the original operator, and to route outgoing calls to the desired operator. Although it is possible to connect several operators directly to an IPBX, it is complex to route calls to the desired operator while integrating a failover function. P-KISS-SBC incorporates a function that allows you to attempt to route the call to a preferred operator and, if this fails, to attempt to terminate the call on a second operator.

 # Connecting an IPBX to more than one operator
 
 For administrations or sites hosting several companies, it is common to use a multi-tenant IPBX, i.e. hosting separate entities that are hermetically sealed from each other. Apart from a hack, it is impossible to connect this multi-tenant IPBX to a telecoms operator via a single trunk. P-KISS-SBC makes this possible:

 # Fail over from a primary to a secondary IPBX
 
 Another simple use case to implement with P-KISS-SBC is IPBX high availability. 2 scenarios are possible. Firstly, failover enabling requests to be sent from the main IPBX to the secondary IPBX without any manual action. The telecoms operator(s) see no change and have no knowledge of the internal telephone infrastructure.
