FIGURE 5: DAG1000-8S& DAG1000-8O SCENARIO/TOLL- FREE CALLING BETWEEN LOCATIONS
In this diagram, configure the SIP Server field to be the IP Address of the other gateway (i.e.
configure IP address of FXS gateway to be SIP Server of
DAG1000-8O
and vice versa). Please be
sure you set SIP Registration to No.
Expected call flow:
Analog Phone (
DAG1000-8S
) picks up and dials destination PSTN number.
The call gets routed to the
DAG1000-8O
which dials out the digit string onto the FXO Lines, thus
reaching the destination PSTN endpoint. On the reverse, incoming calls from PSTN endpoints will
be routed automatically to the FXS Gateway through the
DAG1000-8O
.
