hi all

we are changing one of new customer`s DHCP scope and the phone system IP address. we normally allocate static IP`s.
could anyone please advice me how to go about this please.
 
I assume you mean you use static IP's for the 3300. You can change them by the serial cable on the front of the unit using an RS232 cable or in the system IP properties form. Depending on the controller you may have an E2T card that you would need to manually change the IP address of or at least setup a new static reservation for the E2T. If the 3300 is acting as a DHCP server you would need to add the new subnets to it.

An apple a day keeps the doctor away. Anyone else and you need to throw it harder.
 
What is going to be providing the DHCP, the 3300 or another server?
You can also set the 3300 to only respond to Mitel IP phones so you can run your normal DHCP and the Mitel scope side by side as long as there are reservations put in place so you don't get conflicting addresses.
Do/will you have VLANs in place?
 
hi LoopyLou

thanks for the reply. sorry my question wasn't really clear. i need to change the IP address of the phone system and the DHCP pool to a different range.
i believe i have to change the DHCP options as well???
 
hi sarond

at the moment the 3300 is providing DHCP for the whole network (phones + PC`s) i want to separate the 2 networks. yes there will be a separate DHCP for the PC`s
i have never done it before. so would like to get some guidance pls...
 
If you are truly seperating the networks then why not leave the Mitel as is and use a new range for the pC's on the new server? Save messing with the Mitel.
 
yes true. but the IT guys wanted us to change the phone system side so they could keep the IT side of the things as it is.
how hard can it be.
1.change the system IP
2.delete all the existing scopes and create a new one
3.change the DHCP options
4.reboot the phones

is that it ??
or is there additional stuff.
they haven`t got any SIP suff

 
Sounds about right,
To get the 3300 to only respond to Mitel Phones you would make sure that your 'IP Address Range' had the name 'ipphone.mitel.com'
You also tick the box 'Client's Class ID must match name'
Everything else should be straight forward and pretty much copy and modify what you already have in place, changing scope details as required.

To be honest if you have managed switches you are better off using the capabilities and going with CDP or LLDP to autodiscover VLAN's.
It can also provides QoS on your network which is always advised depending on the size.
 
thanks for the info sarond

there are few ranges on the table. im not sure how to attach a Pic on to this. otherwise i would have posted it.

it says

local 192.168.1.31 192.168.1.94 Pre-Cofig Database (192.168.1.0)
local1 192.168.1.96 192.168.1.131
local2 .......
local3 .......



local7

don't know why its been setup like that.

they have only few phones so the QOS is not a massive issue.
but they have few phones off site ?
do you think i have to manually configure the IP`s for those phones ?

 
It will depend how the offsite phones are connected, are they via VPN? There could be a few ways that it is configured.
With the IP address range it looks like there are reservations i.e. 192.168.1.95 is missing from the addresses. These may be for printers etc...
Are all addresses within the 192.168.1.0/24 range? If so and you are moving to a complete different network scope and you only want to deliver IP addresses to Mitel phones then you be able to get away with one IP address range.
 
yes off site is conected Via VPN. yes im not sure how the off site phones are configured. they might have static IP`s. yes they are going to have 192.168.3.0 range.
and is there anyway that i could use a windows 8 laptop to connect to a 3300. its is using IE 11. cannot downgrade to 10 i guess.
thanks
 
Using Windows 8 (IE11) is a pain, you can use compatibility mode sometimes but I haven't had any luck with java and backups. I usually run a Win7 Virtual Machine to do most of my Mitel stuff.
It sounds like the remote phones could be statically set but there is also a 'trick' where you can set the phone into Teleworker mode by holding down the '7' key while the phone is powering up. This allows you to just enter the IP address of your controller and it will use standard DHCP to get an ip address, as long as there is routing in place for the phone to reach the controller (which I assume you would have with a VPN) it will download its firmware and connect to the phone system.
 
are you using vmware ? yes the routing is in place. yes teleworker setup would do i think. they have one 5201. can i configure teleworker on that too with the same way.
 
Don't think a 5201 can be set as a teleworker.

Thanks guys. everything went smoothly. but one thing DNS was an outside IP address before. now ive changed the system IP, gateway and the DHCP do i have to change the DNS to an internal address.
thing is i cannot connect to the phone system via the data network.
 
I think the DNS only comes into play for the high end sets that can display web content. If you are not doing that I would think you don't need it. The only thing I can think of might be the retrieval of the licenses from the AMC. Not sure if the controller uses DNS to reach the AMC.

Yes DNS is used for AMC licensing. I shouldn't matter that it is an external DNS Server.
So no you don't have to change the DNS leaving it will be fine, I would look at getting routing between the Data and Voice VLANs though just to make life easier.
 
thanks guys. when i try the external address the phone system is not responding. i can see the port 443 is open and forwarding to the phone system internal IP.
but the phones vlan doesn't respond to that.
 
likely routing issues between voice and data vlans.
