Avaya G450 Capacity or G430 with EM200

[Saab1313]

Hello Experts, I am new to this forum.
We are setting up around 60 Analog phones and 150 Digital phones for one of our location.
Can you please advise what are my options for Digital phones

We are installing G450 in that site.can i add G430 as the extension to it or should i add EM200 for the extensions.

Please correct me if i am wrong. I am just new and learning.

Thanks in Advance.

Can you get another G450? They are much easier to service if uptime is important. G430 is a bit harder to work on. G430 is required for an EM200.
