Configuring the PSTN (FXO) Gateway
This chapter describes how to configure the PSTN gateway provided by Linksys ATAs devices
with one or more FXO ports, which includes the AG310 and SPA3102 devices. It includes the
following sections:
•
”Connecting to PSTN and VoIP Services” section on page 74
•
”How VoIP-To-PSTN Calls Work” section on page 75
•
”How PSTN-To-VoIP Calls Work” section on page 77
•

•
”Sharing One VoIP Account Between the FXS and PSTN Lines” section on page 80
•
”Other Options” section on page 81
•

Connecting to PSTN and VoIP Services
The SPA3102 and AG310 devices have the following ports for connection to telephony devices:
•
FXS port (Phone)—Connect to a standard analog telephone or fax machine, configured
by using the Line page.
•
FXO port (Line)—Connect to a standard telephone wall jack for connectivity to the
PSTN, configured using the PSTN Line page.
Line 1 does not provide a gateway because it provides only VoIP service. The VoIP-To-PSTN
calling function is referred to as a
PSTN gateway
, and the PSTN-To-VoIP calling function is
referred to as a
VoIP gateway
. Note the following definitions:
•
VoIP caller—One who calls the Linksys ATA device via VoIP to obtain PSTN service
•
VoIP user—VoIP caller that has a user account (user-id and password) on the Linksys ATA
device
•
PSTN caller—One who calls the Linksys ATA device from the PSTN to obtain VoIP service
Line 1 can be configured with a regular VoIP account and can be used in the same way as the
Line 1 of any Linksys ATA device.
With the SPA3102 and AG310 devices, a second VoIP account can be configured to support
PSTN gateway calls exclusively. A different SIP port should be assigned to Line 1 and the PSTN
Line. The same VoIP account may be used for both Line 1 and the PSTN Line if a different SIP
port is assigned to each.
