is this a coincidence
my hh5 router seams to reboot every 14 day

I think I can say it's no coincidence. My HH5 on Infinity is doing the same. It was 14 days before the last pair of reboots (this morning), and 14 days before that again. I even had several reboots in one night just like your logs show before the 14 day cycle.

(The log doesn't record any dialling home before the reboot, and the firmware is never updated anyway. OpenRG is just software running on the router itself.)

BT are still denying there is any such issue!

OpenRG looks to me to be exactly the sort of software that would dial home periodically to check for updates. From wiki:-

Cisco Videoscape OpenRG (formerly Jungo OpenRG): Our Residential Gateway Software is the world's most widely deployed gateway software. Cisco PrimeHome (formerly Jungo Panorama): The connected Home Manager, let's service providers manage the digital home in its entirety. Cisco Videoscape Service Application (formerly Jungo Rainbow): This is a platform for gateway-integrated services. It lets service providers deploy and support unified applications across different CPE.

Why have you added 2 extra things?
I think the summary of OpenRG you quote says almost exactly what I wrote.
I don't think I said OpenRG couldn't oversee dialling home anyway.
If it did, there is still no reason for the router to reboot when there is no update and this is an issue that needs fixing as the whole local network and internet shuts down for 3 minutes interrupting the end user.

(As an actual HH5 user, I can see from the logs that there are dialling home entries recorded - these do not need a reboot and do not mention OpenRG. When there was a real update, the hub rebooted and this log still didn't mention OpenRG. I don't think there is evidence this is an update/dialling home issue, though it might be related - that's for BT/the manufacturer to sort out anyway)
