We have 4 ip pools (one voice ip pool for VOIP and 3 data ip pools) and our dhcp server is started assigning voice ip pool address to any new laptop or desktop is connected to network.
And when i check my dhcp our primary data ip pool is full and its now started flushing voice ip addresses instead giving secondary data ip pool addresses.
What will be the cause?

Thank you for your reply.
Yes we have a different pool for VOIP. Can I know the correct setup of dhcp relay on router. I am not familiar to this.

This is our configuration and we use sp voice vlan 12 and sp access vlan 1 on our interfaces.
And I also tried removing the sp voice vlan 12 on one interface and connected a laptop but I got a vlan 12 IP address which left me in complete bizarre.
