asterisk users - Dec 2018 - Connected line update prevented

I am seeing the following type of error in the console and verbose log.

Connected line update to PJSIP/mlc296-00000000 prevented

It is happening after a Dial command [Dial("PJSIP/mlc296-00000006", 
"PJSIP/mlcx450,25,IktT")] before the other party answers the phone.

This happens to be dialing from a Digium phone to a soft phone, but I 
also get the message when dialing the other way.
I am using the latest Asterisk 16 and DPMA.

There doesn't seem to be any damage - everything works OK, but I'd like 
to figure out what this means and fix it or prevent it.

I did find 
https://wiki.asterisk.org/wiki/display/DIGIUM/Digium+Phones+and+Connected+Line+Updates
and applied those changes but it did not help.

Any ideas?

That message is not an error.  It is a verbose log stating what it did.  It
is a result
of you telling the Dial application to block the initial connected line
update because
you set Dial's 'I' option flag.
