We removed self compiled stock asterisk with "make uninstall" which keep 
our configuration and installed

Asterisk 20.5.2~dfsg+~cs6.13.40431414-1 built by nobody @ 
buildd.debian.org on a unknown running Linux on 2023-12-22 12:58:28 UTC

We place a SIP call to a mobile phone using a SIP provider with codecs 
set to "allow=!all,alaw", our codecs being "allow=!all,g772,alaw", both 
using PJSIP. Output is below.

We did the same before removing our self compiled stock asterisk and 
didn't had this translate NOTICE, so problem is effective with Debian 
Asterisk package.

Why slin is involved ? We also see it on our production server running 
same Debian version of Asterisk
