@kezo I was thinking the alarm needed to be plugged into the new router, is this not the case? Do we still need a phone line, we don’t use the phone for anything else, we don’t even have a physical phone plugged into the wall socket, it’s just the router and alarm system.
Does your existing alarm setup use a phone line or internet?
It’s hard wired into the back of the BT wall box using the phone line.
Even though you don’t use a landline, you still actually have a phone number and pay line rental and you use your alarm through this?
Therefore you still require a landline or in the case of FTTP you would use VOIP. As far as I know BT include line rental in the price of their packages, unless you specifically state you don’t want a home phone line. The issue going this way is you would need a digital, such as Texecom Monitor, rather than analogue speach dialer for your alarm. The other problem apart from cost, is will AMCO still be able to communicate ovver digital.
The most straight forward option would be BT’s digital voice adaptor as, described previous. This would allow you to use analogue equipment.
