I am investigating an issue with the alarm system at a community hall which I help with technical issues. I am not sure who provides their phone service
If the alarm is 'triggered' it sends a text message to a number of Mobile phones - it does this via an access number [Removed]. This does not seem to be working.
I was doing some investigation at home - when I dialled this number from my landline - it was unobtainable but when I dialled it from my mobile it answered in much the same was as a dial up modem or a fax machine.
My question is - is it likely that this number is blocked from landlines? If so why? Is it possible to unblock it?
