[OpenSIPS-Users] Help: presence not working.

[Friend_14309]

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:mika at 172.17.100.5 via
sip:mika at 172.16.102.11 on behalf of sip:mika at 172.17.100.5 for event
presence.winfo, to_tag=b11fa29be7deff2756188f5829692e66-e5da, cseq=3"

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

*Please help. Thank you.*
