The advanced routing algorithm within the Stillink system is carried out in four steps:
The same routing algorithm is applied for both TDM and VoIP calls.
»»» Incoming A-Party Analysis (optional)
Incoming A-Party (calling-party) analysis is the first (optional) step in Routing Analysis. It is applied to each originating or incoming interface. In order to facilitate this analysis, an incoming A-party analysis table is assigned to the originating user (TDM or VoIP). The incoming A-party analysis is done by analyzing the calling-party`s Number (up to 32 digits), Category, Nature of Address (or type of number), Numbering Plan, Presentation Status, Screening Status, etc. after which any or all of these parameters may be translated and then selected for a called-party pre-analysis table.
»»» Called-Party Pre-Analysis (optional)
The Pre-Analysis is carried out prior to the main called-party analysis to truncate some called-party prefixes or reject certain addresses (destinations) altogether. Telesis has developed pre-analysis in order to simplfy the main analysis, especially for when a Stillink system services several operators in transit mode. Pre-analysis is applied to as many as 16-digit called-party prefixes.
»»» Main Analysis
The main called-party analysis is carried out on the called-party prefixes resulting from the pre-analysis. Up to 16-digit-long prefixes may be analyzed. It is possible to define the minimum and maximum digits for starting the analysis. This analysis is date- and time-dependent, i.e., for different days of the week and different times of the day, the analysis may result in different outcomes:
The route that is decided on after this analysis may be:
»»» Outgoing A-Party Analysis (optional)
Outgoing A-party (calling-party) analysis is the last (optional) step in the routing procedure. It is applied to the terminating or outgoing interface. In order to facilitate this analysis, an outgoing A-party analysis table is assigned to the called subscriber/outgoing trunk. The outgoing A-party analysis is done by analyzing the calling party`s number (up to 32 digits), Category, Nature of address, Numbering Plan, Presentation Status, Screening Status, etc. and, additionally, the Called-Party`s Nature of Address, after which any or all of these parameters may be translated.
