Hi Herve,
please check your mediaproxy process, is it running properly (ps -ef |
grep mediaproxy) and listening on your public IP ?
If the client is behind nat, please make sure it's not using any kind on
STUN server to discover its own public IP, or ICE or whatever, NAT
stuffs are handled by NGCP.

Try to run ngrep-sip and check the SIP messages. SDP part of INVITE to
provider and of 200 OK to the client should contain the mediaproxy's
public IP.
