I am facing SIP Account setting reset issue with some of GRANDSTREAM GXP 1625 phones at one of our client site.
Some working IP Phone’s account settings are getting reset. It happens on random bases and on random phones. It happens on multiple phones at a time.
Whenever this issue occurs, all the account details of that phones are getting cleared automatically. It needs to reconfigure all the SIP account details. After reconfiguration it works fine. But this issue occurs frequently with random phones.
We have checked the phone’s firmware on which issue reported and we have also tried upgrading the firmware of that phone but issue still remains same.(Previous Firmware 220.127.116.11 Upgraded Firmware 18.104.22.168). Please note that, this issue occurs on random phones at a time which have different firmwares.
We have checked all the settings on that phone related to SIP Configurations, like Unregistered on reboot. Tried rebooting the phone after changing the settings, but still no luck.
