How to transfer the called subscriber to the extension with music?

Question

Asterisk

I am making test calls, I need to transfer the called subscriber to an extension, so that both I and he can talk.
At the moment I made such a configuration, but there is a problem: everyone hears the music, but the interlocutor does not hear me, but I do not hear him

[from-internal]
exten => _[0-9].,1,MixMonitor(${EXTEN}_${STRFTIME(,GMT+3,%F_%T)}.WAV,W(1));
exten => _[0-9].,n,Dial(SIP/${EXTEN}@trunk,30,G(music^s^1))

[music]
exten => s,1,Answer()
exten => s,n,MusicOnHold(music)
exten => s,n,Set(TIMEOUT(absolute)=30)
exten => s,n,Hangup()

Answer 1

In a nutshell, try this:
Where confbridge is context, s is extension
