Hi Guys, I'm using FusionPBX version 4.4.5 with freeswitch 1.8.5. I've a Yealink phone, I registered it and registration expiration time is 3600 seconds. Now at very next minute I turned of my yealink phone but on fusionpnx under registration it will show phone is still registered for next 3600 seconds. I tested it on Grandstream and samething happened. If I set expiration time on yealink 120 seconds then it shows registered for 120 seconds and then gone. My concern is system should check after every 30 seconds or a minute and see if phone is not responding so delete the logs from registration.
