Figure 104   SIP > QoS

Each field is described in the following table.   

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.

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.
