Question

Asterisk

Hello.
Asterisk 13.13.1
Through AMI, you can make a call to Astrerisk
I do it like this (call to 101, after picking up the phone it connects to subscriber 105)

Action: login
Username: admin
Secret: passw

Action: Originate
Channel: SIP/101
Callerid: 101
Timeout: 15000
Context: call-out
Exten: 105

AMI CDR outputs call results to console

Is it possible to set some variable when initializing a call through AMI, which could then be seen in the Event CDR ?
What worked and what didn't.
I tried to use
Callerid: 123456789 I
see it in CDR, but at the same time it is visible to subscribers, which is not good.
I noticed that there is a UserField field in the CDR
:
But I can’t get the data to pass there.
I even found a mention that there is / was such a bug
https://issues.asterisk.org/jira/browse/ASTERISK-13744
But, unfortunately, the patch does not apply to the version of Asterisk 13.13.1 Tell me
how can I overcome this problem?
