Exactly correct, as I posted in my last message. The CDR structure is created in memory when the channel is created, and the accountcode field in the CDR is populated.

Because it not passed over IAX2, ever, even in this softphone situation. They are completely different situations.

If the Asterisk server receiving the call from the other server has 'accountcode' set in the type=user entry for the server sending the call, then that value will be in CDR(ACCOUNTCODE) on the receiving server. The value that was in CDR(ACCOUNTCODE) on the sending server is never transferred and will not be visible on the receiving server.
