Need IP Office advise

[bashe]

Hi,
I am new to this forum and hope this membership would help me in the rest of my life with Avaya.
I am an old Nortel customer and is planning to replace our BCM400 with new Avaya IP office. I have around 150 stations in HO. I would like to know the below details:
- What are the maximum capacity of stations I can get with an IP office control unit?
- Each of the stations should connect to IP office control unit directly? or the control unit only goes to the network switch and stations connected to the switch? I would like to know the connection diagram of the IP office stations in my network. I don't want double cabling for single station for workstation and IP phone.

I appreciate your support on this.

thanks

IPO can support two thousand users last I heard. It usually increases with every major release.

IP phones connect to your existing ethernet fabric and communicate across the network to register with the IPO. Analog or digital phones must be wired directly to an appropriate IPO station card.

IP500V2 supports up to 384 users in a mixture of analogue, digital and IP stations.ServerEdition supports up to 2000 users, with 1500 users per server as a maximum.
ServerEdition Select supports up to 3000 users.


The maximum number of users depends on the used server.

Thanks all, that means for ip stations the ipo unit is required just an ethernet connection to my existing LAN. All analog and digital phones are connected directly to IPO unit.

Thanks again

There's a lot more involved in setting up IP endpoints than just plugging your IP Office into the LAN, I've seen a lot of networks where people have two DHCP servers running (their primary DHCP server and then the IP Office) where phones will randomly reboot throughout the day. The best thing to do is buy separate PoE switches for your phones and connect the IP Office to that.

Or just segregate the IPO and endpoints into a voice VLAN. I'd never suggest using the IPO for a DHCP server.

We almost always use IPO as DHCP server inside the voice network. But we never use IPO as DHCP server together with another DHCP server in the same network.
