sipx 4.2.0, using UK ITSP Gradwell.
We have had a number of cases where outbound calls produce a phantom call approx 30 minutes later. This continues until we restart SIP Trunking service. The key seems to be found in sipxbridge.log "2011-04-13T13:24:19.674000Z":21194:sipxbridge:ERR:ha1.testonrelay.local:ReInviteSender-7:00000000:sipXbridge:"Cannot aquire ACK semaphore" "2011-04-13T13:24:19.675000Z":21196:sipxbridge:ERR:ha1.testonrelay.local:ReInviteSender-7:00000000:sipXbridge:"Could not send re-INVITE time out ClientTransaction" "2011-04-13T13:24:19.689000Z":21198:sipxbridge:DEBUG:ha1.testonrelay.local:ReInviteSender-7:00000000:SipListenerImpl:"Timed out processing SESSION_TIMER" "2011-04-13T13:24:19.793000Z":21201:sipxbridge:INFO:ha1.testonrelay.local:ReInviteSender-7:00000000:sipXbridge:"[StackLoggerImpl.java:132][UDPMessageChannel.java:688][MessageChannel.java:255][SIPTransaction.java:745][SIPClientTransaction.java:476][SIPDialog.java:2240][SIPDialog.java:365][ThreadPoolExecutor.java:886][ThreadPoolExecutor.java:908][Thread.java:619]" "2011-04-13T13:24:19.793000Z":21202:OUTGOING:INFO:ha1.testonrelay.local:ReInviteSender-7:00000000:sipXbridge:"Sent SIP Message :\n----Remote Host:212.11.94.100---- Port: 5060----\nINVITE sip:*771065296#[email protected] SIP/2.0\r\nVia: SIP/2.0/UDP 217.37xx.xx:5080;branch=z9hG4bK506ce9c9bf5e99fa9cb713cc27a83a73343031\r\nCSeq: 3 INVITE\r\nFrom: \"sipxbridge\" <sip:[email protected]>;tag=4991709908329197483\r\nTo: <sip:[email protected];user=phone This re-invite happens about 30 minutes after the call and the ITSP interprets this as a new INVITE and places the call.
