Phone reboots on Resync when using Open VPN

[ipcsolutions]

When phones are connected via Open VPN to a SIP server, performing a resync on the phone will make it reboot, even if there have been no configuration changes.
I believe that it did not do it on previous firmware releases.
This release is 66.81.0.110.

This is obviously annoying so I would like to know if this is a bug and if not what I can do to fix it.

Thanks
Mike

It appears to also do the same thing when connected at another site over a VPN. Strange.

Would it be possible to know what parameters cause the phone to reboot?

Thanks

Dear Mike,

This is Johnson from Yealink Technical support team.Nice to work with you.
For this question,please kindly change the "sip.notify_reboot_enable" value via
auto provisioning.

sip.notify_reboot_enable 0, 1 or 2

Description:
Configure the IP phone behavior when receiving a SIP NOTIFY message which contains the header “Event: check-sync”.

0-The IP phone will reboot only if the SIP NOTIFY message contains an additional string “reboot=true”.
1-The IP phone will be forced to reboot.
2-The IP phone will ignore the SIP NOTIFY message.

Any update,please feel free to let me know.
