Hi everyone,
Recently I have a problem bother me long time, I use pjsua to send a sip call to an ip phone, and then after almost 20 sec, my ip phone start ringing. When this problem occur, I checked the asterisk log, I saw many of sip accounts re-registered.
This problem occur very randomly, last time is 4 months ago, and last 2 time is 6 months ago, I restart asterisk then it work normally, but yesterday this problem occur 10 times in one day, I restart asterisk but few minutes later, the problem occur again.
My system has almost 1700 sip accounts, run in a local network.
My server is Cisco C220 M4, asterisk version is 14.3.0.
Could anyone give me some suggestion?
Thanks!
