Hi all, i'm going crazy with an issue with WiFi VoIP users. Our VoIP server, Opensips 1.11.9, was inside DMZ with public IP address 193.x.x.110 and WiFi network is 10.x.x.x. VoIP fixed phone are inside a separated network 172.20.x.x and firewall allowed traffic in both directions between those nets.
When i call from a fixed phone (172.20.1.90, as example) to a client connected to WiFi network (ex. 10.101.8.71) it works perfectly. But, on other side, SIP signalling fail on a PRACK sent to 193.x.x.110 instead of 10.101.8.71, printing out "WARNING:rr:after_strict:no socket found for match second RR" error. 5004 was the CALLED user, 5009 the calling one, on WiFi network (10.10.1.22): /usr/sbin/opensips[29845]: 8EhpJFUAhqwKXTay3zK9S.B3nGLBWUub - Route RELAY INVITE To: 5004, From: 5009, RURI: sip:[email protected]:45802 /usr/sbin/opensips[29845]: 8EhpJFUAhqwKXTay3zK9S.B3nGLBWUub - Route NEW BRANCH To: 5004, From: 5009, RURI: sip:[email protected]:45802 /usr/sbin/opensips[29844]: 8EhpJFUAhqwKXTay3zK9S.B3nGLBWUub - Route RELAY PRACK To: 5004, From: 5009, RURI: sip:193.x.x.110;lr; /usr/sbin/opensips[29849]: 8EhpJFUAhqwKXTay3zK9S.B3nGLBWUub - Route MISSED CALL INVITE To: 5004, From: 5009, RURI: sip:[email protected]:45802 /usr/sbin/opensips[29845]: 8EhpJFUAhqwKXTay3zK9S.B3nGLBWUub - Route RELAY ACK To: 5004, From: 5009, RURI: sip:voip.xxxx.it;transport=udp;lr Oh the 5009 phone i did a tcpdump where i saw: * SIP/2.0 489 Bad Event v: SIP/2.0/UDP 10.0.8.1:34209;rport=53951;received=10.101.8.71;branch=z9hG4bKPjDD2mDOwI11dIEIX-FY-72lpXL2jS9Qvz Record-Route: <sip:193.*x*.*x*.110;lr;ftag=V41fxeL-v5HuRwE4rUnVN-XRVBTsVal3> i: 6znDCyifz4jVTBUDMGe07e2UQrdr2qCl f: <sip:5009@voip.*xxx*.it>;tag=V41fxeL-v5HuRwE4rUnVN-XRVBTsVal3 t: <sip:5009@voip.*xxx*.it>;tag=1eC1ckc8ts5OH4mJhMwZ-RgHxEFUgMJw CSeq: 27800 SUBSCRIBE l: 0 PRACK sip:5004@193.*x*.*x*.110:26892 SIP/2.0 v: SIP/2.0/UDP 10.0.8.1:34209;rport;branch=z9hG4bKPjghFr0FmAkMHZhWMcfUtl1mUxj-IdkyQg Max-Forwards: 70 f: <sip:5009@voip.*xxx*.it>;tag=KgJWD-2L-MlmTD0FyxgXhlnUeIIOhYbM t: <sip:5004@voip.*xxx*.it>;tag=aewrc0nu91 i: 8EhpJFUAhqwKXTay3zK9S.B3nGLBWUub CSeq: 13112 PRACK Route: <sip:193.*x.**x*.110;lr;ftag=KgJWD-2L-MlmTD0FyxgXhlnUeIIOhYbM;did=b8.6fcc5694> RAck: 1 13111 INVITE l: 0 SIP/2.0 404 Not here v: SIP/2.0/UDP 10.0.8.1:34209;received=10.101.8.71;rport=53951;branch=z9hG4bKPjghFr0FmAkMHZhWMcfUtl1mUxj-IdkyQg f: <sip:5009@voip.*xxx*.it>;tag=KgJWD-2L-MlmTD0FyxgXhlnUeIIOhYbM t: <sip:5004@voip.*xxx*.it>;tag=aewrc0nu91 i: 8EhpJFUAhqwKXTay3zK9S.B3nGLBWUub CSeq: 13112 PRACK Server: VoIP Content-Length: 0 *Any hints how to solve this issue ?
