VLAN's
I am brand new to VLAN's so please excuse my ignorance. We have an AllWorx VoIP phone system that has been on our regular network for a few years. Our employees plug their phones into the network port at their desk then plug their laptops into their phone's (yes we have WiFi but wired is much more reliable). So each phone gets an IP from the DHCP Server then acts as a switch and each laptop gets an IP from the same DHCP server. We are growing and starting to run out of DHCP addresses on our LAN. If I set up a VLAN for the phone system would employees still be able to plug into their phones and get an IP Address on our network?
This depends on the type of phone that is been used. when they support a voice vlan. then it is posible what you wanna do.
when they dont support. just make youre subnet one bit larger.

Arnold,
Thanks for your response. The Phones are plugged into network port via ethernet cable. The laptops are connected to phones via ethernet cable. The DHCP server then hands out IP's to both Phone and Laptop. Right now all IP's are in the 192.168.1.0/24 range. Are you saying if I tag the phones based on MAC address I can have them receive an IP....for arguments sake...of 10.10.1.xxx and the laptops connected to the phone would still receive 192.168.1.xxx?
Am I simply better off changing the subnet and increasing the DHCP pool??

There are other vendors but this covers the example... That may clear things up and help you out,
Make sure to add IPs of the VLAN you are adding to router on which the VLAN needs to also be defined to make sure if they need internet access they can have it.

the DHCP allocates an IP to the phone, which is then tethering the device/pc using bluetooth/usb?
yes separating the two will make more space possible depending on your switch, you could tag the vlan based on the MAC of the device
Voice Vlan will get all phone devices, while the other devices will be on a data vlan....
