Hi Jorge,
The error generated by udp_send usually translates into a local iptables
blocking the destination or source IP of that message. Maybe the
re-INVITE gets some wrong IPs in the RURI (when routed via OpenSIPS).
You can simply check where OpenSIPS will try to route the re-INVITE by
adding after the loose_route() :
xlog("after loose route ru=<$ru>, du=<$du>\n");
Check if the du or ru do point to something impossible to route to.

Hi all,
I have a OpenSIPS between SBC and Asterisk PBX. This SIP Proxy relay
outbound calls from PBX to SBC.
Some calls when it is answered SIP Proxy receives from SBC a REINVITE
or INVITE in-dialog, sometimes those REINVITES make fail SIP Proxy and
it doesn't relay.
- In log:
ERROR: core: udp_send: sendto (sock, 0xb5ec5464,938,0,0xb5f4950c, 16):
Operation not permitted (1)
ERROR: tm: msg_send: udp_send failed
ERROR: tm: t_forward_nonack: sending request failed
- In pcap I can see that SIP Proxy does not relay REINVITE and it
returns "477 Send failed (477 / TM)"
I have checked REINVITE SIP traces OK and KO but i can not see any
different.
What could be the problem?
Thanks
Regards.
