Hello Klaus,
I had already two sockets bound each to two independent physical interfaces. I have added the force_send_socket at each rtpproxy
It is necessary to use the cwie / cwei flags in the rtpproxy_manage call?
Currently audio does not flow back to the softphones, it gets lost at Kamailio.
Thank you for your help

The next test has been to comment out the rtpproxy_manage at NATMANAGE function and to put it both at route[RELAY] and onreply(route) following your post in this list from January 2013:http://lists.sip-router.org/pipermail/sr-users/2013-January/076254.html.
Now the media flows from Phone1 to Kamailio, from Kamailio to Asterisk and back, but it gets stuck at Kamailio. I cannot see it flow towards the public IP of the Phone2.
The force_send_socket you used could be of any use here?
That's what I recommend:
- use 2 sockets, one for communication with internal nodes, one for
external clients
- in your Kamailio config check the direction of every message: i->e or
e->i (for requests and responses). Depending on the direction set the proper IP when calling manage_rtpproxy and force the send socket:
