We have a single SIP provider one our IP Office 500V2 running 8.1. Our connection to them is publicly routable and while we have not been hacked, we are probed constantly. So, I began looking into an SBC. The VAR that set up our system originally wants $9-$12K to install either an Avaya SBC or a Mediant 500. Price of the equipment is $2k-$3k + some licensing/support and then they want $4k-$6k to configure the stupid thing for 1 SIP provider. It seems outrageous to me. Does anyone have any recommendations on alternatives or input into how feasible doing it myself would be? I do network administration but have limited experience in advanced topics though I do have some experienced network admins that I reach out to when I get stuck.
