find out your phone number by dial several numbers on the phone.
I need to replace a phone line from the NID to my home.
The NID outside my home(5-story) has about 12 phone lines connect to
it.
I don't want to dissconnect my neighbour's phone line when replacing
it.
Last week, when verizon(NY) came to my workplace and did some repair.
I saw them just connect a test tool and dial several numbers on the
phone to retrieve the number that belong to that line.
I saw they also successfully retrieve it using a regular phone.
Does anyone know what number to press in order to retrieve the phone
number?
