Slicing and Aggregation
Being able to group call data according to business-relevant criteria is key to many use cases. For example, enterprise customers of CSPs are increasingly demanding voice quality SLAs. With Qrystal you can obtain the data by defining a SIP trunk for each customer using the IP address of the SBC terminating the traffic of that customer.
A different example is given by a wholesale carrier who wants to report on call quality by origination and destination. This is done by introducing a numbering plan, which defines number prefixes, for example for countries and mobile networks. A-party and B-party numbers are matched to entries in the numbering plan. The link between calls and numbering plan entries can be used in a variety of ways, for example to report on the call quality of a business customer for calls to Singapore.
The configured trunk and numbering plan grouping is applied to each call and thus to all correlated streams. Throughout Qrystal, you may use these groups and aggregates to select a subset of calls or media streams to analyze or report on.
