This section describes PSTN redirection operations associated with the AT&T In-Band Transfer Connect℠ service. Details of the service are described in AT&T Technical Reference 50075
on the AT&T Web site.
NCR provides Information Forwarding support for the AT&T In-Band Transfer Connect℠ network service ISDN D-channel data-forwarding capability. The Information Forwarding feature forwards the UUI that is associated with the call to the redirected-to location. When Call Vectoring and AT&T In-Band Transfer Connect℠ are used to transfer a call and NCR is enabled for the system, the disconnect vector step causes UUI IE information to be inserted into the ISDN DISCONNECT message generated by a successful AT&T In-Band Transfer Connect operation.
Note:
For information on NCR administration and other administration measures that are required when the AT&T In-Band Transfer Connect℠ service is used, see Administering Avaya Aura® Call Center Elite.
AT&T In-Band Transfer Connect℠ operations can be initiated by Call Vectoring after performing the following administration steps:
Administering a route-to number vector step with an announcement extension, where the associated announcement is recorded with Dial Tone Multi-Frequency (DTMF) tones that include a *T followed by a PSTN endpoint number.
Administering a BSR location VDN Interflow field on the BSR Application Plan screen as an announcement extension, where the associated announcement is recorded with DTMF tones that include a *T followed by a PSTN endpoint number.
Administering a BSR location VDN Interflow field on the BSR Application Plan screen as a local switch VDN number associated with a vector that contains an announcement step, where the associated announcement is recorded with DTMF tones that include a *T followed by a PSTN endpoint number.
When the route-to number vector in action 1 is executed or when a queue-to best vector step is executed and the BSR location described in action 2 or action 3 is selected as the BSR best location for call interflow, the AT&T In-Band Transfer Connect℠ operation succeeds, but no UUI IE information is sent to the redirected-to PSTN endpoint by Communication Manager. However, for step 3, NCR can be administered for use with the AT&T In-Band Transfer Connect℠ service and a disconnect hearing announcement none vector added after the announcement step such that UUI information associated with the call is passed to the routed-to endpoint when the call redirection is completed. This UUI information can be used in agent screen pop-ups at the redirected-to PSTN endpoint where the call is interflowed.
