On Thursday 27th November 2014 at 14:00 GMT we will be performing an upgrade of our Yealink provisioning service.
We don’t envisage this causing any appreciable downtime. Just please be aware that if you are deploying phones at this time there may be a delay in provisioning.
The good news is that once this has been done, we will be able to offer an extra layer of security using HTTPS client certificates in Yealink phones that support this.
Regards,
The ProVu Technical Team.
