Hi,
I'm going crazy with this problem, so maybe anyone here can see any
error or can give a hint how to debug this.
I've two clients behind (the same) NAT. INVITE goes thru, so does 100
and 180. But the 200 isn't relayed because of the following syslog error:
./sbin/openser[23933]: ERROR: udp_send:
sendto(sock,0x81816a8,814,0,0xb5b7f168,16): Operation not permitted(1)
./sbin/openser[23933]: msg_send: ERROR: udp_send failed
I can't find any error (the two Via headers are exactly the same), so
here is the 180 which is relayed without problems, and below the 200,
which causes the error:
