After about one month of FIOS our phone stopped working but the Internet access continued to work. So I tried to contact Verizon through the web for service. After numerous attempts with no confirmation of receipt I ended up having to call them. To their credit they came the next day. The tech explained that when FIOS was installed the installer failed to disconnect the copper line which blew out. He disconnected it - and voila!
The only fly in the ointment is that if we tried to switch carriers, for instance, to ATT who leases the copper lines from Verizon - we can't because the copper line from our house to the pole is now blown. M thinks that this is all a conspiracy by Verizon to keep its FIOS customers.
