Check the line using an old conventional plug in phone. You should always keep one for power cuts. Also, get someone to phone your number.
One a three handset system, the signal to all three are driven by the main unit, the bit with the answering system. Check that is plugged in to the mains wall socket and if it is, check for power at the socket. If that checks out, you need to check that little plug in power supply unit. Best way is with a test meter. If the lights are on on the unit and the answer machine works, then you know you have power at that unit, so you need to check the power supplies in the slave units.

First you should try a "Reset' on each phone, if this doesn't remedy the issue, than that conclusively proves that they have been damaged due to some electrical power borne problems. When, this happens, usually the phones are a total loss, as the damage done, is often weird and unpredictable damage has been done, often to the power supplies inside the units and or the main control boards, I have found usually they are an uneconomic repairs. In saying that however i see no harm in one contacting the manufacturer and asking for a referral to an authorized service center, and then when referred, then ask them, for a "Quote" before proceeding with any repair.
Toll Saver is the most confusing option with little or no information about it anywhere.
It overrerides the number of rings settings so that the answering voice mail cuts in after 4 rings or 3 if there are new messages. If you want to set rings to 6 or 7 or more, or have a consistent number of rings before voice mail cuts in, you have to turn off "Toll Saver".
Does the phone base receiver also have power? If so, then it sounds like a phone wire may have been cut. How extensive was this electrical work? If an electrician cut your phone wire by mistake they should take care of the problem at no charge.
To eliminate any problems with your cordless phone, try plugging in a standard phone where your cordless unit is to see if the line works.
it may be setup to block outbound calling, remember also, you have to dial a 9 to get dial tone on a centrex line, so in this case if your phone system is setup to dial 9 as a line access code you will actually have to dial 99. hope that helps
