PJSIP gives up re-registering when a REGISTER request expires, i.e. after PJSIP_REGISTER_CLIENT_DELAY_BEFORE_REFRESH (5 s). A more robust behaviour would be to re-register after PJSUA_REG_INTERVAL (300 s). However the register callback (regc_cb in in pjsua_acc.c) is never called again when the REGISTER request once has expired. I guess this has something to do with the registration structure being destroyed and that the re-registration timer is also destroyed along with it? This behaviour has been observed when using PJSIP on symbian mobiles phones (symbian_ua), where REGISTER requests can get lost in the network quite often. To temporarily overcome this problem we tried to increase the PJSUA_REG_INTERVAL to 3600. This strangely caused PJSUA to register at least every second. We tried PJSUA_REG_INTERVAL=1800 which worked ok, but this is only a temporary solution. Any suggestions ? -------------- next part -------------- An HTML attachment was scrubbed...
