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.
