11.7 Phone
You can configure the volume, echo cancellation and VAD settings for each individual phone port on the ZyXEL Device. You can also select which SIP account to use for making outgoing calls.
11.7.1 PSTN Line
With the PSTN line you can make and receive regular PSTN phone calls. Use a prefix number to make a regular call. When the device does not have power, you can make regular calls without dialing a prefix number.
"When the ZyXEL Device does not have power, only the phone connected to the PHONE 1 port can be used for making calls. Ensure you know which phone this is, so that in case of emergency you can make outgoing calls.
