Figure 131   PSTN to PSTN Example: General Configuration
An outgoing authentication account needs to be configured. This account consists of the 
IP address and port number of the branch office ZyXEL Device as well as the username 
and password for authentication. This username and password must match the incoming 
authentication account username and password on the branch office ZyXEL Device. The 
name of this account is “CityB” referring to the branch office ZyXEL Device. In this 
example the username is “headquarters” and the password is “password”. This can be 
configured in the VoIP > Trunking > Peer Call screen. 
Figure 132   PSTN to PSTN Example - Outgoing Authentication 
A call rule needs to be created. This rule tells the ZyXEL Device which remote peer 
device it should connect to in order to complete the call. This rule is composed of a 
pattern and an account name. This pattern is simply the first several digits of the number 
you want the remote device to connect to. In this example this is the first 4 digits 
(“5555”) of “Sales1” telephone number. The account name is the name of the outgoing 
authentication account created in the Speed Dial screen (“CityB”). This setting can be 
configured in the VoIP > Trunking > Call Rule screen.
