Since CDR function is deprecated in Asterisk 13.
How to set a custom variable in realtime Database using CHANNEL(Mycustomfield)
I keep getting "func_channel_write_real: Unknown or unavailable item requested: Mycustomfield"
Before "CDR(Mycustomfield) = newvalue" used to work. and now "CHANNEL(Mycustomfield) = newvalue" does not.
I am using asterisk 13.6.0
