Bug#1060275: asterisk: Codec translation notice

[Daniel]

Package: asterisk
Version: 1:20.5.2~dfsg+~cs6.13.40431414-1
Severity: normal
Tags: upstream

Dear Maintainer,

after upgrading from Debian11/asterisk 18.20.2 compiled from source to Debian12/Asterisk 20.5.2 from unstable, we receive lots of NOTICE logs like

[2024-01-08 11:35:31] NOTICE[58221][C-0000028a]: translate.c:603 ast_translate: 18182 lost frame(s) 48240/30057 (alaw at 8000)->(ulaw at 8000)
[2024-01-08 11:35:31] NOTICE[58710][C-00000298]: translate.c:603 ast_translate: 1253 lost frame(s) 1254/0 (slin at 16000)->(slin at 8000)->(alaw at 8000)

doesn't matter IAX2 or PJSIP endpoints. We are surprised to see such notice between alaw & ulaw. Codecs used for PJSIP and IAX customers EP are
!all,g722,ulaw,alaw and for providers !all,ulaw,alaw

We checked translation and tried by adding slin,slin16 on both sides, no changes. On 18.20.2 we didn't have this behaviour.

Answer we get from asterisk community list "If you’re using the Debian package, then that includes patches which are not present in Asterisk mainline.
Those log messages, and some codec translation behavior, is from one of those patches."

Thanks for your support
