Codec error, although I have allowed all codec

I am using PJSIP and my call is dropping due to code, I already installed opensource G729 codec too. But I found there are many translation paths unavailable. How can I install not available translation paths

I am getting the following error in calls

Channel.c:5707 set_format: Unable to find a codec translation path: (jpeg|png|h261|h263|h263p|h264|mpeg4|vp8|vp9|red|t140|g723) -> (ulaw)
[Apr 3 14:00:47] WARNING[24155]: channel.c:5707 set_format: Unable to find a codec translation path: (ulaw) -> (jpeg|png|h261|h263|h263p|h264|mpeg4|vp8|vp9|red|t140|g723)

And when I used command

core show translation paths ulaw
Than I get following result, there are many No Translation Path

Could you tell me what would be solution for it

2

The code may not handle allowing absolutely every codec possible. Normally people limit to the ones they expect, which I believe works fine.

3

But I have put all allowed, so whatever codec is coming should it not work? and how can I solve this problem by specifying one codec?

You would configure in the endpoint the codecs:

allow=!all,ulaw,g722,g729,opus

Etc.
