This is a popular scenario which does not involve any SIP Server or IP PBX. This scenario allows an organization
with a remote location to access the local FXO trunks (Traditional PBX trunks or PSTN lines) through the IP network.
In the diagram, remote users in Boston have standard analog phones connected to the GXW400x FXS Analog
Gateway, while corporate users in the Denver location use a traditional PBX whose FXO trunks are connected to a
GXW410x FXO Analog Gateway. With the help of the IP infrastructure and Grandstream GXW FXO and FXS Series,
the remote users in Boston are able to make, as well as receive calls from Denver as if they were at the same
location.
