AMI Action ATXFER setting Variables not working

Asterisk Asterisk APIs

I’m trying to set some variables on AMI atxfer action command the following way

ami.action({
                'Action': 'Atxfer',
                'Channel': channel_id,
                'Exten': `Local/${to}@${rec.context}`,
                'Variable': {
                    'IFI_UUID': session_id,
                    'IFI_AGENT': rec.username,
                    'IFI_DID': rec.caller_id,
                }
            }

Call is being transferred correctly, but newly set variables are not working, instead it’s carry-forwarding the previous variables. Any way to set new variabless by any means?

Update: The call is not routing through rec.context valiable I passed. Instead, it’s going through internal context. I’m getting log like this Local/9999999999@from-internal-xfer-00000dc3

I also tried to inherit the variables key as @khamlichi.khalil suggested. But, no luck.

I believe a transfer is carried out on a newly created channel, so you newly set variables are set there and not in the new where the transfer is actually made, you could try to :
1/ add __ to all the vars (IFI_UUID → __IFI_UUID) to allow inheritance of those variables.
if this does not solve it you could try :

1/ set variable TRANSFER_CONTEXT = “my_attxfer_context” on the call
2/ add __ to all the vars (IFI_UUID → __IFI_UUID)
3/ inside my_attxfer_context reset the vars again or do any logic you see fit

None of these worked. I updated the question with what I tried and the update.

That AMI action[1] has no such functionality to set variables. It would need to done some other way. As well it’s exten and context, in the dialplan.

I think that error comes from the common failure to understand that an extension, in Asterisk, is only what appears to the right of “exten=>” in the dialplan. Almost everyone here uses extension to refer to devices, as does FreePBX.

after this comment :

you can use manager action SetVar along with TRANSFER_CONTEXT (you need to create this context in your dialplan)

Yes, I did the same to achieve my goal, finally.
