Hello! I occasionally can see warnings like these during *idle* times in asterisk log (asterisk 13.7.2):
[2016-06-05 06:11:51] WARNING[27817] pjsip: sip_transactio Unable to register REGISTER transaction (key xists) [2016-06-05 06:11:51] WARNING[27817] pjsip: sip_transactio Unable to register REGISTER transaction (key exists) Nothing more. The third REGISTER package works as expected. What's going on: My phone regularly (each 7.5 minutes) sends REGISTER. Sometimes, those REGISTERs are denied like seen above (mostly already the second REGISTER works and no third REGISTER is needed). The reRegistering of the phone normally works like this (as seen in wireshark): -> REGISTER 06:04:19:285 <- 401 Unauthorized 06:04:19:287 -> REGISTER 06:04:19:316 <- 200 OK 06:04:19:376 If warnings happen like the one mentioned above, the following can be seen in wireshark: -> REGISTER 06:11:49:359 <- 401 Unauthorized 06:11:49:362 -> REGISTER 06:11:49:392 Unable ... -> REGISTER 06:11:49:876 Unable ... -> REGISTER 06:11:50:868 <- 200 OK 06:11:51:634 The second, third and fourth register package look completely identical to me according wireshark regarding SIP. Notice the big latency between the fourth register and the following 200 OK: there are nearly 0.8 seconds in between in the problem case - but normally, there are just 0.06 seconds between REGISTER and 200 OK! What happened during these 0.8 seconds? Asterisk (and the complete machine) has been completely idle at this time - there wasn't any call or anything other to process. I've got the complete wireshark trace of the situation described above. Any idea?
