asterisk users - Oct 2019 - different logs in messages vs syslog

Hello,

I am logging into messages and also to syslog.
Here is my /etc/asterisk/logger.conf:

     messages => notice,warning,error,verbose
syslog.local0 => notice,warning,error,verbose

But the logs look different:

[2019-10-20 12:02:06] VERBOSE[7609][C-00000013]  pbx.c:
            Executing [1111 at fullaccess:1]
Answer("SIP/2222-0000000c",
"") in new stack
vs.

 2019-10-20 12:02:06  VERBOSE[7609][C-00000013]: pbx.c:2925 in
pbx_extension_helper: Executing [1111 at fullaccess:1]
Answer("SIP/2222-0000000c", "") in new stack

specifically, the messages coming from syslog have extra information
(which I am not interested in):

such as:

pbx.c:                              Executing ...
pbx.c:2925 in pbx_extension_helper: Executing ...

or,

netsock2.c:                    Using SIP RTP CoS mark 5
netsock2.c:661 in ast_set_qos: Using SIP RTP CoS mark 5

(I have aligned them for better readability)

How can I get rid of the unwanted extra information ?

thanks,
