what hardware to choose for VoIP? need assistance

Hello!

I'm looking for cisco hardware to build VoIP system.

I want to replace my old ISR2811 and Avaya PBX with one central cisco device.

I think it would be ISR G2 with modules, but I need Your help to assist what exactly hardware, software and license do I need...

There will be about 50 telephones, one fax.

Re: what hardware to choose for VoIP? need assistance

Personally, I'd probably look at going this route:

Order a server with CUCM Business Edition. It supports up to 500 users, will replace your Avaya PBX, and comes with a co-resident install of Unity Connection voice messaging as well. Then I'd use that 2811 as PSTN gateway with a couple PRI (T1/E1) for inbound/outbound connectivity. You would need to purchase licensing for CUCMBE and CUWL licensing (or the new term for it) is typically the way to go. If you truly want a single device, I don't know that I'd go ISR G2 just yet ... but you could. However, for less money - you could upgrade to a 2821 with CME and that, I believe, should be plenty. I'm not big on the express products but that's just me...they certainly work and have come a long way feature-wise.
