Dual Network Gateway on CentOS 6.7

I have dual NIC machine running CentOS 6.7 and asterisk. First NIC is for LAN & Internet connectivity and second is for trunk provider's connectivity. Both of these have gateways configured. I don't seem to be able to access the Internet as the traffic is routed thru the Second NIC's gateway, also the second NIC is taken as default route by the kernel. I do not understand how default gateway is assigned in this case and what correction should I do.
