Mitel voip and sonicwall with limited nodes
Posted on 2012-09-10
I have a sonicwall that is connected to a network with 8 computer. The sonicwall is limited to 10 nodes connections at one time. I have 6 mitel voip phones that acquire their ip with the sonicwall dhcp. The mitel phones connect to a T1 line, so the phone only need the get an ip from the network but they do not use the networks internet to make or receive calls. All phone communication goes through the T1 line and all network data through a dsl line.
When i attempt to use the sonicwall for the network dhcp the phones also receive an ip with that dhcp. Because of the 10 node limit I have either phones that are not working or computers that will not connect to the internet because the total is 14.
I would like to separate the networks so that the phones get their dhcp from another device such as a router or server. When i have the server setup to handle the dhcp i still get the 10 node limit, so the sonicwall recognizes that it has a dhcp and restricts access.
What i am considering doing is setting up a switch that will separate with vlan the two networks (voice and data) and have the computer go to the sonicwall network and the phones go to my server's dhcp. Is that possible and will i need to setup a separate nic to achieve this?
