I have three cisco 3750 switches configured in switch stack with 2 vlans (one voice, one data) on a network with about 9 vlans. The issues I'm having is that the users from 172.16.9.x network cannot contact the phone server on 192.168.10.x network. Packets are hitting the swith but everything is being sent out the gateway including phone server packets. I have setup port monitoring and changed the users gateway to the switch and still no luck. Is there some way to accomplish this without a third party device (router or firewall)? Is some kind of trunkng possible? I can post the configs if you need them. Please help! thanks.
The switch IP is : 172.16.1.2
The switches gate: 172.16.1.1
Users are on 172.16.9.x
IP phone system in on 192.168.10x
