Ensure the reachability of the call server from that port. To ensure the same, configure a laptop with the IP address and default gateway of the intended IP phone. Then try pinging the call server from the laptop.

If this works then the setting should work for IP phone too. Double check on the router IP address and Vlan ID configured on the phone.
