Hi all, On analyzing PJSIP could see TCP and UDP socket uses same port. But in PJSIP 2.7 there is no option of SO_REUSEPORT.How UDP data is received when TCP socket is closed. +++++++++++++++++++++ Registered an U.E with IMS network.Then I do a un-register(ru) .Later should I need to do a register to re-register with IMS network?? Tried rr but Re-register is not working. ++++++++++++++++++++++++++++++++++++++ Any suggestions? Thanks P.S.Manika Vasagam

Hi, this is a portability issue, but basically, SO_REUSEADDR does the same. Did you configure tcp switching ? Check the file: pjsip/include/pjsip/sip_config.h TCP Switching can be enabled/disabled at config state. E.g: pjsip_cfg()->endpt.disable_tcp_switch = PJ_TRUE; A really good explanation can be found here: https://stackoverflow.com/questions/14388706/how-do-so-reuseaddr-and-so-reuseport-differ Best regards Franz ________________________________ Von: pjsip <pjsip-bounces@lists.pjsip.org> im Auftrag von Manika Vasagam <psmanik@gmail.com> Gesendet: Dienstag, 11.

TCP and UDP are separate protocols. Binding/closing/whatever a TCP socket on port X has nothing to do with a UDP socket on port X. Just think about a socket being locally identifiable by its {protocol, address, port} triplet.
