W52P - VPN Reboot

[mkeuter]

Hi,

I am using a W52P (FW: 25.73.0.25) through a OpenVPN tunnel with Asterisk 11.
All works fine, but when I reboot the phone, it seems as if the phone tries to send registration messages out of the tunnel to Asterisk shortly after I start the reboot. I always get these ACL errors on reboots of this phone. E.g.

Code:

Nov 18 13:49:49 asterisk local0.notice asterisk[1798]: NOTICE[1828]: acl.c:748 in ast_apply_acl: SIP Peer ACL: Rejecting '31.19.xx.xx' due to a failure to pass ACL '(BASELINE)'

Asterisk is configured to allow only registrations from the virtual 10.8.x.x OpenVPN address range.
All other Yealink phones I tested (T42G, T38G) behave fine. But they have an option "unregister on reboot" which is disabled. I don't know if that is the reason. I have a SIP trace which I can send you privately.
