Due to the tree search algorithm implemented in the call router very large routing tables can be scanned very quickly with minimal impact on the call setup delay. The SmartWare call router supports the following routing criteria:

•Calling party number (calling-e164); also called source-Nr, A-Nr, MSN, DDI, or CLIP

•Called party number (called-e164); also called destination-Nror B-Nr

•Calling and called party number type

•Calling and called party number plan

•Calling and called party name, the display name

•Calling and called party IP address (for VoIP calls)

•Calling and called party URIs (for SIP calls)

•Presentation indicator; whether the number shall be presented to the other party

•Screening indicator; whether the number has been screened

•Information transfer capability; also called ISDN bearer capability or ISDN service
