File does not exist in any format

file  /var/lib/asterisk/sounds/custom/*           

Don’t worry linux is poly-glottal

output of
file /var/lib/asterisk/sounds/custom/: "/var/lib/asterisk/sounds/custom/Hang_001: RIFF (little-endian) data, WAVE audio, Microsoft PCM, 16 bit, mono 8000 Hz
/var/lib/asterisk/sounds/custom/Hang_001.wav*: RIFF (little-endian) data, WAVE audio, Microsoft PCM, 16 bit, mono 8000 Hz"

well, somehow you have it as

/var/lib/asterisk/sounds/custom/Hang_001.wav*

it should be

/var/lib/asterisk/sounds/custom/Hang_001.wav

so

mv /var/lib/asterisk/sounds/custom/Hang_001.wav\* /var/lib/asterisk/sounds/custom/Hang_001.wav

For sanity remove the confusing file with

rm /var/lib/asterisk/sounds/custom/Hang_001

I tried everything but it doesn’t work😭

Saying ‘it doesn’t work’ is just not helpful and saying you ‘did everything’ just plain incorrect, post logs and other details as per this thread, yes post them all again.

When I say to asterisk: “core reload”, I get 86 error messages

Do you want me to guess what they are, or are you going to post them ?

“Trunk limited to 32,000 characters; number of characters entered: 105478.” (I can’t do that :blush:)

post some maybe , no mind-readers here :wink:

[2022-04-22 19:41:03] WARNING[57377]: pbx.c:8551 ast_context_verify_includes: Context ‘app-callwaiting-cwon’ tries to include nonexistent context ‘app-callwaiting-cwon-custom’

That’s not an ERROR, it is a WARNING.

And has nothing to do with the asterisk filling the sounds?

No, ERRORs are a problem WARNING’s not so much, post your 86 ERROR’s

This is it: [2022-04-22 19:41:03] WARNING[57377]: pbx.c:8551 ast_context_verify_includes: Context ‘app-callwaiting-cwon’ tries to include nonexistent context ‘app-callwaiting-cwon-custom’

But this not an error

Again, (patiently) that is NOT an ERROR.

grep ERROR /var/log/asterisk/full|tail -86

Each is just a warning

Then stop doing core reload and post your ‘not working’ bits from /var/log/asterisk/full

if you are not using ari or ldap ignore those

Likely you have more than one transport bound to the same port and chan_pjsip will not work if chan_sip is similarly bound, either untangle that or best disable chan_sip
