setup a network with 192.168.1.X AND192.168.2.X?
We have a network of 120+ users and 20+ servers. We are switching our phone's to VOIP and we will shortly run out of ip addresses. Currently we have a range of ip addresses from 1-254. We need to either extend the range beyond 254 or add a secondary scope of ip addreses. How would we go about doing that?
Actualizar:Would the machine's on the secondary subnet mask be able to communicate with the machines on the original subnet mask?

If you are adding VoIP, then you may want to put the voice traffic on it's own vlan. if your router is not capable of understanding VLANs, then you may want to upgrade that as well, as it probably doesn't understand other Class of Service (CoS) parameters. CoS will improve the performance of your voice solution during times of heavy network congestion.
so while you CAN simply increase the size of your subnet, and it will solve the problem of the number of IPs, it will probably also introduce a whole other bunch of problems when you deploy a VoIP solution.
I don't want to sound like I'm here to sell you anything, but I'm an engineer at a network manufacturer/vendor, so if you contact me i can give you some product recommendations.
Modify the subnet mask. Change it from 255.255.255.0 to 255.255.252.0 and you'll extend it to cover that address range in a single subnet.
Use a subnet. Simply change the subnest mask to 255.255.0.0 on all devices. This will then open up everything in 192.168.X.X. You will then be able to use 192.168.1.x, 192.1168.2.x, etc.
