messages ( using sip MESSAGE request ) or sending call invites.
Sometimes it works well and fast, sometimes it doesn't, sometimes
messages are delivered very slowly. With two last options ( doesn't
work at all and/or messages are delivered slowly ), I get the
following errors:
ERROR:core:tcp_blocking_connect: timeout 10 s elapsed from 10 s
ERROR:core:tcpconn_connect: tcp_blocking_connect failed
ERROR:core:tcp_send: connect failed
ERROR:tm:msg_send: tcp_send failed
ERROR:tm:t_forward_nonack: sending request failed
My devices are behind NAT ( mobile phones ) and I am using pjsip with
tcp connection.
Moreover I am trying to set up a persistent connection and hope, that
server will reuse it, when it needs to send something. I am sending
keep-alive packets every 600 seconds and I am not using any STUN or
TURN servers.
My opensips and rtpproxy are running on EC2, so are behind NAT as well.
And I don't have any STUN or TURN servers intalled ( should I install
any of it? )
Any help, advice or suggestions would be highly appreciated!
