The phone line won't respond when the TiVo unit dials out, even though phone service is available.

1. If this is the first time you have noticed a failed phone connection, it is best to simply wait a few days and allow the DVR to continue to make its automatic connections to the TiVo service.

2. To resolve the issue, perform the following steps:

    a. Power cycle the DVR by unplugging both the phone cord and the power cord from the back of the DVR. This will release the phone line and reset the modem. Wait at least 15 seconds, then reconnect both cords and test your connection to the TiVo service. If the test connection fails, continue with Step 2. To test the connection, refer to the following:
         i. Software version 3.0 - 3.2: Go to TiVo Central by pressing the TiVo button on the remote control. Highlight Messages & Setup; then Recorder & Phone Setup; then  Phone Connection; then Make Test Call. Press SELECT to begin the test.
         ii. Software version 4.0 and later: Go to TiVo Central by pressing the TiVo button on the remote control. Highlight Messages & Setup; then Settings; then Phone & Network Setup; then Test connection. Press SELECT to test the connection.

b. Check the Phone Dialing Options:

        i. Software versions 3.0 - 3.2: Go to TiVo Central by pressing the TiVo button on the remote control. Highlight Messages & Setup; then Recorder & Phone Setup; then Phone Connection; then Change Dialing Options
        ii. Software version 4.0 and later: Go to TiVo Central by pressing the TiVo button on the remote control. Highlight Messages & Setup; then Settings; then Phone & Network Setup; then Edit phone or network settings; then Phone Dialing Options.

c. Verify the Phone Availability Detection option is set to Off (the default). You may have a low voltage phone line, which may prevent the DVR from detecting the dial tone even if the Phone Availability Detection option is set to On.
       i. Check the Set Call Waiting Prefix setting. If you do not have call waiting, verify a call waiting prefix is not entered. If you do have call waiting, set the call waiting prefix to *70, (star seven zero comma). To enter a comma press PAUSE, and to enter a star press CLEAR. Press SELECT to accept the setting. You will then be prompted to test the connection

3. Additional notes:

a. The phone modem is only compatible with analog phone service. If you are using a digital phone service provider such as cable, Verizon, etc. the phone modem is not compatible and will not function properly. If you have a high speed internet router you may use a network connection instead of the phone line. Please use the following link to locate a list of compatible network adapters. www.tivo.com 
b. If you have DSL internet service, please be sure that you have a DSL filter on the phone line that is connected to the TiVo
       i. Try changing the dial in number. This can be done from TiVo Central/ Messages and Settings/ Phone Settings/ Dial in number

Using TiVO without a telephone line connection:

1. If the TiVo unit has been connected and has updated to at least version 7.1 software (within the last 2 years) the unit can do Guided Setup using a network adapter instead of the phone line. The unit can also use the network connection to download channel listings. Please use the following link to locate a list of compatible network adapters. http://www.tivo.com/setupandsupport/messagesonmydvr/Which_Network_Adapters_Work_with_My_TiVo_DVR_.html
