No sound coming

Hello

I called my mailbox using my ata and even the tho Asterisk says which sounds are playing, I don’t hear anything

Here is my users.conf

[6000] fullname = Joe User email = joe@foo.bar secret = 1234 host = dynamic dtmf = auto hasvoicemail = yes vmsecret = 1234 hassip = yes hasiax = no hash323 = no hasmanager = no callwaiting = yes context = google-in

and my voicemail

What can I do to fix it?

Thanks
