Blocking a number from Landline

I'm in a rented property; and the home's alarm system dials a 13 number approximately once per week, which is the base of the security company the previous owner used.

 

This costs me a small, but annoying charge each time.

 

The security company has confirmed the call does nothing as there is no account with our residence any more. The only way I've been told to fix this is to have the security system re-programmed NOT to call. Unplugging the phone line will just cause an error.

 

It requires an expensive service call to have the unit re-programmed; and the real-estate & I are now engaged in an arguement as to who'se responsibility that is.

 

One way to resolve it is if the landline in question can be set to block that specific outbound number, thus defeating the security system without re-programming it.

 

I cannot find anything online about how to do it.

 

Is it possible?

 

How do I do it?

 

Thank you.

Re: Blocking a number from Landline

I don't believe it can be done however that would theoretically cause the same error as just unplugging the phone line anyway I would think... because the error is going to come about based on not being able to get through to its base and confirm details....

Re: Blocking a number from Landline

Hello, I can't see any reason why you simply don't unplug the phone line plug. It does not matter if there is an error, because the alarm is out of service,    You can also unplug the power source, eith electricity plug or battery, as the battery will discharge unless it is topped up by electricity

Thanks
