We use a hosted PBX system with our 3710. It seems to be hit and miss whether the remote pin works or not. When the intercom makes the call out to the mobile - which works fine we have a 4 digit PIN which is entered followed by #. I am aware there is a short delay before door released. However although it has worked, it stopped working, then it worked and now it’s stopped working again. Don’t believe we have changed anything other than the fact that we do change the guest PIN on a regular basis - but we have not changed any of the other settings.
Anybody aware of any fixes
