The TATA SIP trunk required a dedicated LAN interface in your asterisk server whereas one LAN port occupied for the local network and second LAN for TATA network
Configure the TATA network ip to the free LAN interface in server.
Edit the ifcfg-eth2 file
nano /etc/sysconfig/network-scripts/ifcfg-eth1 IPADDR=10.0.30.10 PREFIX=30 ONBOOT=YES The ip address 10.0.30.10 provided by TATA
Configure the route to communicate with TATA network
SIP trunk network always on different rather than the local network ip of your so static route to be require to communicate with TATA SBC
Create a new file
nano /etc/sysconfig/network-scripts/route-eth2 Insert the following based on the SBC IP provided 10.0.30.4/32 via 10.0.30.11 Save the file and restart network service
Once network service restarted check the route is added by using route -n
