Hi Bogdan and all, > I will post the issue at the eyebeam support forum.
After many struggles I now come back to the OpenSIPS mailing list, because I think now that it is a problem of OpenSIPS and not that of the SIP clients. The problem is, that the clients use an ephemeral port for outgoing TCP connections which is (as far as I have seen always) different from the port they advertise for incoming connections. The problem for the inbound proxy is to setup a separate TCP connection in this case. I did not have a NAT environment; therefore the existing connection has not been re-used. The problem gets obviously an additional complexity as in case of TLS a separate TLS connection has to be setup (now in the reverse direction). OpenSIPS in this case has problems to setup this second TLS connection showing: ERROR:core:tls_blocking_write: too many retries with no operation ERROR:core:tcp_send: failed to send ERROR:tm:msg_send: tcp_send failed ERROR:tm:t_forward_nonack: sending request failed I think now, that this is still an open issue in the implementation. regards Franz _______________________________________________ Users mailing list Users@lists.opensips.org http://lists.opensips.org/cgi-bin/mailman/listinfo/users
