Anonymous caller ID rewrite / rename

Hi @all,

I am trying to rewrite incoming anonymous calls to display the name and number field as “anonymous.”
As this is a regulatory requirement.

I asked the mighty chatgpt and got this answer:

ASTPP allows you to define rules for manipulating and rewriting Caller ID information. To configure ASTPP to display “anonymous” for incoming anonymous calls, you would typically follow these steps:

  1. Log in to the ASTPP web interface with your admin credentials.
  2. Navigate to the “Routing” section or a similar menu option that handles call routing and manipulation.
  3. Look for options related to Caller ID Manipulation or Call ID Rewriting.
  4. Create a new rule or edit an existing rule for incoming calls.
  5. Set the condition to identify incoming anonymous calls. This condition might involve checking the Caller ID field for a specific value (such as “Unknown” or “Anonymous”).
  6. Define the action to rewrite the Caller ID information. In this case, you would set the name and number fields to “anonymous.”
  7. Save the rule and apply the changes.

However I cannot find the coresponding menus / entries.
I have ASTPP v5.0 Enterprise.

Can anyone help with this?

thanks in advance,


ChatGTP does not have the ability to look up for information on the internet. As a result, when lacking information for a response, it will start making up information.

Of course this could be on version 6 of ASTPP Enterprise.

Or you could use Bing Chat which uses ChatGTP with the ability to do Internet searches.


I know that chatgpt does not have ALL the information, but regardless this is what I need to achieve, and I think that Astpp is capable of doing this I just don’t know how.



Using Bing’s ChatGTP, I got a better response as I suggested you use:

I found a web page that explains how to do anonymous caller ID rewrite/rename on ASTPP. Here is the link to the page:

The page provides a step-by-step guide on how to do anonymous caller ID rewrite/rename on ASTPP. It also includes screenshots to help you follow along. I hope this helps!

However, it seems iNextrix has removed that page.


I am a bit lost, I understand you found a better solution but the site is down, still I think ASTPP is capable of doing this. I just hope someone had a similar issue and can provide a pointer on how to achieve this.

Kind regards,


There is the documentation, but contains nothing about any such ability.

If nobody responds on how to, I did find this for FreeSwitch itself

@Tibor, you should modify effective_caller_id_name/number in dialplan accordingly.
