What kind of ISR do I need for a SBC for intercompany TP

[marrachart]

Hi,

We've a TP environment met 14 single screen TP endpoints and would like to make an interconnect with another company to expend our reach.

What kind of ISR do I need to terminate the interconnect on (for address hiding) and how do you calculate what kind of ISR you need for this?

Many thanks.

Documents references to the Cisco XR12000 series routers but what is the lowest possible ISR which you can use and how does it scale up?

For instance, is a 2900 of 3900 series capable of doing the inter-company communication and how many sessions can it handle?

I run a CUBE IOS on a 3845 for TP intercompany and it works fine, but we've never run more than 2 x CTS-3000s accross it do I

don't know how well it will scale.  CPU usage isn't too high though.

It can handle   5 session of CTS 3000.

If the calls are CTS 1000, you could increase the call capacity to 5 * 3  = 15.
