If you are having difficulties making or receiving calls on your JT landline, then it could be because of a problem with the network. As part of your rental agreement with us, if the fault is on the JT network we will send out an engineer to fix it, and you will not be charged.
However, some faults may be caused by a problem with your internal wiring or equipment. JT is responsible for the line up to and including the NTP (Network Terminating Point) - The point in which our network cable enters your home or premises. If an engineer visits and the source of the problem is proved to your internal wiring or equipment, you will be charged for the visit.
