lines to the destination PSTN. Most of the configuration on the Gateway for this case will
remain default, except Stage Method needs to be set to 1, and SIP Server IP Address/DNS
name has to be filled.
FIGURE 4: FUNCTIONAL DIAGRAM OF SIP-Server & DAG serial
For incoming calls from the PSTN analog endpoints to the
DAG1000-8O
, the device will auto
forward each call to a configured IP extension or DAG serial
’
s FXS ports. The SIP Server can then
route the call based on its own configuration or IVR system.
B. FXS Gateway with DAG1000-XO [No SIP Server required]
Alternatively, the
DAG1000-XO
(Ex.
DAG1000-8S
) can be used without a SIP Server. You can use
it in conjunction with a FXS Gateway (Ex.
DAG1000-8S
) and still be able to originate and terminate
calls from IP to PSTN and vice versa. All you need to make sure is that the 2 gateways are able to
locate each other (they should be on the same LAN or on Public IPs).
