Automatic Number Identification 

If your switch contains a voice-synthesis board, ACA referral calls are 
accompanied by an audible message identifying the type of ACA infraction 
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.

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 voice or data connection. 
(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 

, your trunk group receives 

*5553800*81120*. If the field is set to 

, 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.

Refer to 

‘‘Trunk Group’’ on page 967

 for information about setting Inband ANI 

on the trunk group form.
