Hi,

You do not need pua (Presece User Agent) to simply do presence between end-points.

Could you run opensips in full debug mode (set debug=6) and send me (off list) the entire log generated by opensips ?

Hello,

No, there no NAT in my test network, just simple static routing.
also, No. There is no other Error message before that "udp_send" ERROR message.

One thing that I would like to ask is, I did not install "pua" modules. Are they necessary if I am implementing simple presence server i.e. everyone is allowed to see the presence of each other.

Thank you.

    Hi,

    Do you have any kind of NAT in your used network (like one of the
    clients behind a NAT) ?

    Also, before the "udp_send" ERROR, do you see any other error from
    the same process ?

    Hi. I am new to this world, so please help.
    I am trying to set up a lab. I have 2 DHCP servers and a SIP server.

    My DHCP server ans OpenSIPS are working fine. But, when I
    register my clients to SIP server, I can not see there presence,
    though I can make call between clients.

    I get these messages,


    "INFO:presence:handle_expired_subs: notify"

    "INFO:presence:send_notify_request: NOTIFY sip:[email protected]

    "ERROR:tm:msg_send: udp_send failed"
    "ERROR:tm:t_forward_nonack: sending request failed"

    *Please help. Thank you.*
