Please log in for more thread options I am getting ready to implement a VOIP system in our organization. I have a couple basic issues that I'm not sure I'm understanding properly. I currently have a basic 10.0.0.0 network. I have 5 sattelite areas (10.0.x.0) routed back to my main network. I am trying to decide whether to put the IP phones on a seperate subnet from my existing devices here. I am implementing layer 3 PoE switches. I'm assuming the advantages are that all the voice traffic would be on a seperate subnet, and the basic disadvantage would be added complexity in programming/routing my other phone systems. Phones & PC's would then have sperate connections in each office. Phones go to the PoE switch & subnet, PC's would go back to my other swtich. If I go this route, some of my switches in outer buildings here would have to have devices from two different subnets plugged into the same switch. WIth layer 3 switches I assume this is OK. Any reasons I may not want to or be able to do this. Is it worth it to seperate these? | |||||||||||||

> - Show quoted text - Yep, good old VLANs would do the trick. Keep in mind most IP Phones have an extra Ethernet port so you wouldn't need a separate drop for the PC's | |||||||||||||

Yeah, I did some reading on vlans. Is there any advantage to running a seperate subnet vs. using vlans? Our phones will have two ethernet ports, but I guess in the interest of sompletely seperating the traffic, I was planning to use dual cables and seperate subnets (or vlans). | |||||||||||||

Well by using vlans you are essentially running two separate subnets. | |||||||||||||
