M4 EU Roaming Regulations

This gui will show how to bill the call with different Tariff based on the call's CallerID.

Using this functionality (starting from version 1.0.200)

Here we have:

• Use Tariff : XXXXX
  • If CallerID matches Rule-Set: Number Pool Rule Set
    
  • Use CallerID Number from PAI Header if available: No / Yes
    
  • and if Destination: do not use/matches/not matces Rule-Set Number Pool Rule Set
  • Using this option it is possible to Use other tariff if CallerID matched Rule-Set. It is possible to create a Rule-Set at Maintenance - Number Pools. Also, it offers possibility to use CallerID Number from PAI Header if available.
• Default Tariff - Tariff used for OP accounting if previous option is not used.
  

For the calls which come from the EU, you need to create a Number Pool where you will enter prefixes of the EEA countries: https://en.wikipedia.org/wiki/Telephone_numbers_in_Europe#European_Economic_Area

Select Tariff in Use Tariff : XXXXX field for such prices.

For the calls outside EEA, select Default Tariff

It is adviced to check YES on 'Use CallerID Number from PAI Header if available' to take CallerID from PAI field if available. If there is no PAI field, then normal CallerID will be used.

It is important to note that CallerID will not be changed. E.g CallerID from OP will be sent to TP. Example, if CallerID is 'anonymous', and PAI has normal CallerID, the call will be billed based on PAI and CallerID 'anonymous' will be sent to TP.
