4. UA (phone), gateway or other hardware/software involved:NA

5. Your problem: We are planning to install BSS in AWS cloud. We may have 20-30 dial plans. BSS will be used for
a) 302 Redirect Server: We will be using the alias and webget function. We may have 50cps.
b)B2B Proxy: We will be using BSS as B2B proxy for SIP Signalling only. We may have 15-20 cps with 400-600 concurrent calls with signalling only (no rtp).

What kind of AWS instance is recommended for this kind of work load?
Instance Type: A1/M4/T2/T3?
Cores:??

Any help would be much appreciated.

I think T2 is fine but I recommend T3.
