Digit Manipulation of Inbound Calls
 

Hello;

I need to set up some digit manipulation in my AACM (not SIP trunks, no session manager) that will truncate the first 5 digits of the inbound ANI and route based on the last 5 digits. How do I remove the first 5 digits of an inbound call? Doesn't ARS only work on outbound calls?

HI Ley1,

You have to make the entry in the "inc-call-handling-trmt trunk-group" & do what you want to delete or where you wanna to route the call.

If you send the calls to A vector you can also set up a variable that would be a set length and start at position 5 then route based on tha variable in a later step.

Why Use ANI to Route Calls
 

I'm just curious as to why you do not route calls based on DNIS digits. I have found that we do not always get the ANI string. So would that not be unreliable?

I do use ANI for time to time. But I use it to "dump" callers who regularly spam or harrass our staff by using a vector routing table (VRT). I route these specific calls to a vector called Dump. It plays the intercept tones and an anouncement I recorded that says: "Your call cannot by completed as dialed ..." twice and drops the call.:cool:

You can also change the trunk preferences (page 2):

Digit Handling (in/out): overlap/overlap
Digit Treatment: insertion
Digits: 0*

Then change ars digit-conversion:

*123456000 min: 10 max: 10 del: 6 add 987 ext

This way, an incoming call to 123456000 will be changed to 9876000
