[Freeswitch-users] Hardware requirement for 1000 Calls

[Uday kumar]

Hi,

Normally will 50 calls CPS. Call is normal call using SIP nothing else
encryption. For codecs please advise. I am thinking to use G729. Yes all
call will go through dialplan. Yes we use park, waiting, transfer etc.
Recording will be saved on same disk. We are planning to purchase dedicated
100mbps bandwidth from data center nothing else in network.

Thanks Uday.
