Cannot get original callerid in attended transferred extension

Asterisk Asterisk Dialplan
1

Hello, community.
I have a question about the original caller’s information in a transferred call.

There are three endpoints (A, B, C).

When making a call from endpoint A to endpoint B, CALLERID(num) is for endpoint A and EXTEN is for endpoint B in the extension.

However, if you transfer this call to endpoint C using atxfer in features.conf, CALLERID(num) is for endpoint B and EXTEN is for endpoint C in the transferred extension.

Is there any idea to get the number of endpoint A in the transferred extension?

Thanks.

Howdy! Welcome to the forums.

You might want to look at your Asterisk logs and see what happens when B dials C. Is it possible for you to manipulate the Caller ID there ? One helpful app is DumpChan() to let you look at what’s available at that moment.

Some additional relevant documentation to consider:
