Extend the mitel Network to add new ip phones

[Tecknew]

Hi Friends,

I am very new to the forum as well as to the world of ip phones. Hope to learn a lot from here.

we are having a mitel 3300 system in the office and I have a new requirement to add 4 new ip phones.

1. There is a separate network only for Mitel system.

In Lan/Wan Configuration -->Layer 2 Switch it shows 

Voice Vlan ID 1
Data Vlan ID 1

Can I use a Unmanaged  switch to extend the network and add 4 new IP phones?

2. In the current setup, phones (Mitel 5312 ) are connected only with RJ45 cable. I think POE is being used.

Should my new switch be POE ?

Thank You in advance.

Somebody please help me.

If you have separate vlan's for voice and data, they shouldn't and can't be VLAN ID 1.

Yes, your new switch would need to provide PoE unless you purchased individual PoE injectors for the phones.

You could use an unmanaged switch, but there is the potential that it may not pass the vlans, so you'd be better of finding a small managed PoE switch.
