Hello Everybody, when my iOS4 App (iPhone4, iOS4.1, PJSIP 1.8.5) is put in background, everthing (e.g. KeepAlive re-regstrations) works as expected (or hoped, rather :-)) for about two hours. Then, all of the sudden, the re-registration fails. This happens, without the device even being touched... Attached is the relevant part of the debugger log. It seems, as if the keepAliveFunction() kicks-in with it's re-registration disturbing the process of UDP socket replacement. - My implementation of "KeepAlive while in backgound" is copied from the pjsua-reference-implementation. It would be very nice, if someone could shed some light on this. - And, how can this situation be avoided? Thanks in advance! -Thomas 05:15:28.957 ioq_select Attempting to replace UDP socket 16 05:15:28.957 ioq_select UDP has been replaced successfully! 05:15:28.957 ioq_select Attempting to replace UDP socket 17 05:15:28.957 ioq_select UDP has been replaced successfully! 05:15:28.957 ioq_select Attempting to replace UDP socket 8 05:15:28.963 ioq_select UDP has been replaced successfully! 05:15:37.158 tcpc0x868014 TCP client transport created 05:15:37.161 tcpc0x868014 TCP transport 192.168.1.102:50312 is connecting to 87.230.73.56:5060... 05:15:37.162 pjsua_core.c TX 599 bytes Request msg REGISTER/cseq=15699 (tdta0x84ac00) to tcp 87.230.73.56:5060: REGISTER sip:sip.finotel.com;transport=tcp SIP/2.0 Via: SIP/2.0/TCP 192.168.1.102:50312;rport;branch=z9hG4bKPjlvyPHfXBGzgkdHr.XJ.gR9b-s9s8vStO Route: <sip:sip.finotel.com;transport=tcp;lr> Max-Forwards: 70 From: <sip:1234567890@xxxxxxxxxxxxxxx>;tag=VSVH1a93g6a0F3U0mxbHZQ-CZMHnSwph To: <sip:1234567890 at sip.finotel.com> Call-ID: MnwrxqSE1aQrm.7clhFkCgJkTBM4Xcv7 CSeq: 15699 REGISTER User-Agent: SIP01 Contact: <sip:1234567890 at 82.113.104.242:25238;transport=tcp> Expires: 300 Allow: PRACK, INVITE, ACK, BYE, CANCEL, UPDATE, SUBSCRIBE, NOTIFY, REFER, MESSAGE, OPTIONS Content-Length: 0 --end msg-- 05:15:37.179 tcpc0x865214 TCP transport destroyed with reason 70016: End of file (PJ_EEOF) 05:15:45.966 ioq_select Attempting to replace UDP socket 10 05:15:45.966 ioq_select UDP has been replaced successfully! 05:15:45.966 ioq_select Attempting to replace UDP socket 11 05:15:45.966 ioq_select UDP has been replaced successfully! 05:15:45.966 ioq_select Attempting to replace UDP socket 12 05:15:45.967 ioq_select UDP has been replaced successfully! 05:15:45.967 ioq_select Attempting to replace UDP socket 13 05:15:45.967 ioq_select UDP has been replaced successfully! 05:15:45.967 ioq_select Attempting to replace UDP socket 14 05:15:45.967 ioq_select UDP has been replaced successfully! 05:15:45.967 ioq_select Attempting to replace UDP socket 15 05:15:45.967 ioq_select UDP has been replaced successfully! 05:15:45.967 ioq_select Attempting to replace UDP socket 16 05:15:45.967 ioq_select UDP has been replaced successfully! 05:15:45.967 ioq_select Attempting to replace UDP socket 17 05:15:45.967 i2010-11-24 05:15:45.972 SIP01[1173:307] keepAliveFunction --- BEFORE re-registration : timeout = 600 acct.expires = 0 oq_select UDP has been replaced successfully! 05:15:45.967 ioq_select Attempting to replace UDP socket 8 05:15:45.973 sip_reg.c Unable to send request, regc has another transaction pending 05:15:45.976 ioq_select UDP has been replaced successfully! 05:15:45.987 tcpc0x868014 TCP connect() error: Connection refused [code=120061] 05:15:45.987 tsx0x885464 Failed to send Request msg REGISTER/cseq=15699 (tdta0x84ac00)! err=120061 (Connection refused) 05:15:45.987 pjsua_acc.c Unable to create/send REGISTER: Object is busy (PJSIP_EBUSY) [status=171001] 05:15:45.987 pjsua_acc.c SIP registration failed, status=503 (Connection refused) SIPStack::__registrationStateChanged(SIPAccountID 2) Status = Service Unavailable --- Expires in -1 seconds 05:15:45.988 pjsua_acc.c Account id 2 deleted 05:15:45.988 tcpc0x868014 TCP transport destroyed with reason 120061: Connection refused 2010-11-24 05:15:45.988 SIP01[1173:307] keepAliveFunction --- AFTER re-registration : timeout = 600 acct.expires = 0 05:25:46.074 ioq_select Attempting to replace UDP socket 10 05:25:46.074 ioq_select UDP has been replaced successfully! 05:25:46.074 ioq_select Attempting to replace UDP socket 11 05:25:46.074 ioq_select UDP has been replaced successfully! 05:25:46.074 ioq_select Attempting to replace UDP socket 12 05:25:46.074 ioq_select UDP has been replaced successfully! 05:25:46.074 ioq_select Attempting to replace UDP socket 13 05:25:46.074 ioq_select UDP has been replaced successfully! 05:25:46.074 ioq_select Attempting to replace UDP socket 14
