"Telcos Announce Digital Network Rollout:-
Both Optus and Telstra have announced that they have commenced rolling out their digital networks that will see the closure of PSTN switched networks using copper infrastructure and replacing it with fibre to the pit or the curb and voice over IP for the telephone communication. This will mean that Security Alarm Diallers using DTMF format may be effected from today. Please be aware that loss of communication or multiple call costs could result and be the only sign that rollout has occurred near your premises.
So check your phone bills. Your alarm could be running up huge bills!!"
