But if it can ring means that the voice should also transport.

Does your mobile operator support SIP at all? Usually in mobile networks the mobile device only gets an private IP address which is firewalled by the mobile operator at the gateway to the internet.
If this firewall is not aware of (or blocked for) SIP traffic it might very well be the case that the outgoing (on UDP port 5060) SIP invite message reaches your asterisk server, thus the phone rings but there is no “return” path for the RTP traffic.
