I just noticed recently that my phone kept rebooting after resync. In the config, i set the resync period for 86400 sec or 24 hours so i didn't pay attention to this issue until i came to my desk and found that my phone was rebooted. Then i change the resync period to 120 sec to experiment and i found that every time, the phone was rebooted immediately after resync happened. It is hard to check what paramter in the config that tricks the phone to reboot but luckily, i found that. It is the below parameter which is for Solicited Voicemail Updates
We were having the same issues, and I resolved 'em by doing a wholesale delete on configuration options (never quiet tracked down *which* one it was). I don't know if this is the only option, but fwiw, I can replicate it now :-)
Actually, I found another issue when i set that Message Waiting Indicator parameter to No. Everything looks good so far when there is no voice mail. After i left a voice message to that phone, the notify msg (message summary) has toggled the light on. Once the phone downloaded the config file, it reboots again. I assume that when the Notify msg toggles the light on, it changes the Message Waiting Indicator parameter to "Yes". Then when the phone downloads the config which has "No" for this parameter, it will reboot because there is an update paramter in its config. This happens to both 7.4.6 and 7.4.7.
Also the problem also happens to these two parameters as well. (I have Call Feature Sync with Broadsoft).
Whenever i press DND or CFWD always key, the phone will reboot every time that it downloads its config file. To avoid this, i have to delete those two parameters in the config file. It is also true for the Message Waiting Indicator paramter too. When i delete it from the config file, it solves the problem.
