I forgot to write, the remote asterisk has:

[internal]
...
include => extensions

[extensions]
exten => 4,1,Dial(SIP/4,15,trw)
exten => 4,n,GotoIf($["${DIALSTATUS}"="BUSY"]?vmail:line2)
exten => 4,n(line2),Dial(SIP/54,20,rw)
exten => 4,n(vmail),Voicemail(4)
exten => 4,n,Voicemail(4)
exten => 4,n,Hangup()

So on the remote asterisk there is context [internal]

I even noticed starting asterisk-16.30 is much slower than starting Asterisk-16.16
