In the UX system, 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 Servers, fax machines and analog phones.
In order to route any call to or from a call system connected to UX, 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 UX 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 UX system to an internal Lync 2010 server or analog phone or fax devices connected to a Tenor Analog device.
UX Call Logic Steps
- An outside call comes through the ISDN PRI line connected to the UX system and is routed to the ISDN Signaling Group.
- In order to route the call, the UX ISDN Signaling Group system engages the Call Route Table attached to it.
- UX processes the Call Route Table entries and their attached Transformation Table entries, looking for a match to the called number.
- UX finds a match for a 4xxx local extension managed by a Lync 2010 Server.
- UX finds a match for a x2001 or x2002 local extension analog device, managed by a Tenor Analog system.
- UX routes the call to the appropriate Signaling Group and the receiving system processes the call.
