Re: what hardware to choose? need assistance

In regards to IOS, any ISR router will work for you.  The CUBE is a border element that will proxy and hide your internal network from external SIP connections, such as your PSTN provider not having direct access to CUCM or CME.   CUBE is a little overkill for what you need.

The size of the router will depend on the number of SIP connections coming to/from your endpoints such as avaya and OCS.   Its really just SIP to SIP and dial peers on the router to make this work.

The trick is will OCS *and* avaya talk the same SIP to/from the router.    2900/3900  or 2800/3800 will work fine for your application.  If its small, you can probably get away with 1800 series
