The IP address of the LAN interface of the router which connects Location A to the public internet should
be configured as Default Gateway in the Network Parameters of SARVAM UMG at Location A.
With the Static Routing Table configured, all calls made by SARVAM UMG to 192.168.2.0/ 24 will be
routed through the router which connects Location A to Location B. Whereas, all calls made by SARVAM
UMG to addresses other than 192.168.2.0/ 24 will be routed through the Default Gateway.
Similarly, configure the Static Routing Table in SARVAM UMG at location B to enable calling from Location
B to Location A.
