Hi. Our company bought a UC520 for us to get to grips with VOIP. As the company's growing, we're now interested in a larger system (Basically we want everything that our UC520 has CME / CUE wise, but bigger). Ive specced up the following, does it look OK (No more than 30 phones)
Baciscally I assume I need to buy the AIM module because unlike my UC520, CUE isnt inbuilt into the 2811?
We currently have BRI in our UC520. We're going to rip the ISDN 2 off the wall and get it replaced with an ISDN 30, will the VWIC2 card i've specced be the correct one?
And finally DSP's... were only going to have possibly 3 phones that will be remotley connecting over a WAN, does the 2811 have any inbuilt DSP's or do I need to buy some?
