1165Automatic Number Identification
20
If your switch contains a voice-synthesis board, ACA referral calls are
accompanied by an audible message identifying the type of A CA infr action
encountered. The message is “Automatic circuit assurance <long> or
<short> holding time threshold has been exceeded for trunk group <#>
member number <#>.”
■Voice Message Retrieval
If you use Voice Message Retrieval, you can assign a nondisplay telephone
as a referral destination.
■Wideband Switching
ACA treats wideband-trunk calls as a single-trunk call and therefore
triggers a single referral call. The call information shows the lowest
B-channel trunk member associated with the wideband channel.
Automatic Number Identification
Inband Automatic Number Identification
Your switch uses Inband Automatic Number Identification (ANI) to interpret
calling party information, such as a calling party number or a billing number.
Inband signaling is when information such as the address digits for the called
party is delivered over the same trunk circuit used for the v oice or data co nnection.
(Out-of-band or ISDN signaling is when signaling information passes through a
different signaling path than the one used for the voice or data connection.)
When a call is made from 555-3800 to your display phone at 81120, and the
Incoming Tone (DTMF) ANI field is set to *ANI*DNIS*, your trunk group recei v es
*5553800*81120*. If the field is set to ANI*DNIS*, your trunk group receives
5553800*81120*. In both cases, Call From 555-3800 appears on your display.
If you do not use Inband ANI, the incoming trunk group name appears on your
phone display.
