Call routing
The call routing capability of GroomerII is a feature that underlines its adaptability, enabling the resolution of many problem scenarios. For example, network providers have installed GroomerII as a means of connecting their enterprise customers’ PBXs, running a variety of disparate protocols, to their networks. GroomerII, operating as a single call routing platform, simultaneously performing the necessary multiple protocol conversions, is employed to connect and route all calls to the provider’s network. Using GroomerII in this way avoids the otherwise excessive cost of upgrading every PBX with the hardware and protocol software needed to connect to the service provider’s network.

GroomerII can be used to provide the following call routing applications:
|
|
Flexible call routing provides full arbitrary routing across multiple incoming trunks and groups to multiple outgoing trunks and groups |
|
Alternative routing, from a prime communications link, for overflow and fallback, may be implemented from a wide choice of scenarios |
|
Least cost routing, with or without call concentration, means calls may be transparently re-routed across specified lower cost routing centres via public or private, TDM and IP networks |
|
Number translation using parameters in call setup messages, such as CLI/ANI or DDI, underpins GroomerII’s ability to perform least cost routing and many other useful operations |
|
Multi-port concentration means a number of incoming timeslots on different trunks, perhaps with different published directory numbers, can be routed to a single outgoing trunk on GroomerII |
|
Address translation is achieved via 3rd party SIP Proxy server interactions, while a look-up table (user populated database) within GroomerII is used for local routing of IP calls |
|
Database connectivity, via an ODBC interface, provides the ability to perform complex queries on external customer database systems, allowing number lists of 100 000+ entries to be checked as part of GroomerII’s routing function |
|
Number portability can be used to provide a cost-effective call re-routing service, via a leased line to the mobile operator, for location independent calls placed initially to a fixed line DDI number or IP phone |
|
CLI (ANI) -based routing can be used if needed to route calls from an authorised or registered user only; if a call is authorised the onward routing is determined by GroomerII’s routing tables |
|
DDI (DNIS) -based routing is used in one of two ways on a route-by-route basis; typically used to prevent access to premium rate or inquiry numbers, it can equally be used to allow access only to certain DDI (DNIS) or IP phone numbers |
|
Time of day scheduling permits GroomerII to route to alternative destinations, dependent on the time of the day or week (e.g., during peak hours or at weekends) the call was placed |
