sundance-communications.com/forum Forums TDM Business Telephone Systems Avaya - Lucent Telephones & Systems Does external expansion module need additional user license?

I have a Avaya IP Office 500 v2 R9.0, the licenses installed listed below:
IP Endpoint 2
Receptionist 1
PRI additional channels 12
Essential Edition 255

It has 4 station base cards with 24 digital ports and 8 analog ports and they are all used.
So I need add a IPO500 digital station 16 external expansion module to it, but not very sure about the license.
Any help?

No license needed to add that module.

The reason you pay so much for those expansion modules is partly because you are buying the ports and can use 16 phones without purchasing any licenses. With IP phones, you purchase a cheap VCM card but every IP phone needs a license to work.

Are there 4 DS8 cards in the IP500?

Strange setup. Looks like 3 DS 8 and 1 analog with PRI ????

3 DS8 and 1 analog base cards

yes, you are right. And it's PRI 20

Thank you for your reply.
So for the essential edition, it could have as many as 255 digital and analog handsets, is that right?

For IP phones, every IP/DECT/SIP handset requires ONE IP Endpoint license, is that right?

I believe your are correct.
Maybe Mongo could confirm.

The Essential License is just an entitlement to Essential Edition. It will allow your IP500 to go up to 384 extensions. If you buy a digital module, you are paying for the hardware, so there is no license per port for digital or analog.

But, yes, if you want to use an IP extension, you would need an Avaya IP endpoint license.

If a third party phone (SIP) then it would be a 3rd party IP endpoint license.

Thank you, Mongo!
Some other phone system, like NEC SV8100, has the issue of license of more than 64 ports. It means extra license required if the extension ports (including virtual ports) exceed 64/256.

Another question about the procedure to install external module, I think it should be: shut down control unit, power it off, then connect external module to control unit, power external module up, power on control module at last.
IP office will configure the external module automatically, and some programming jobs to reconfigure it.
Is the procedure right?

Basically yes.
Power up the Expansion module.
let the light go green.
Plug into IP500
Reboot IP500
Upgrade Expansion module (just like normal upgrade)
