In the (SBC), all call routing occurs between Signaling Groups.
Signaling Groups are the logical representations of call-handling systems such as private branch extensions (PBX), Microsoft Lync 2010/2013 Servers, fax machines and analog phones.
In order to route any call to or from a call system connected to SBC, you must first configure a Signaling Group to represent that device or system. The following list illustrates the hierarchical relationships of the various Telephony routing components of a SBC call system:
Signaling Group — describes the source call and points to a routing definition known as a Call Route Table
Each call routing entry describes how the call should be routed and also points to a Transformation Table which defines the conversion of names, numbers and other fields when routing a call.
The diagram below illustrates possible paths of a call from an external call from a ISDN PRI service line connected to the SBC system to an internal Lync 2010 server or analog phone or fax devices connected to a Tenor Analog device.
