I have been approached to setup a small call centre. I would like to use asterisk to distribute incoming call to remote locations via voip (eg softphone on remote PC).
We are a predominantly mac environment and the issue of media gateway presents some possible NAT/ Public IP address problems (from what I can gather).
The idea is a number (say 6) of incoming pstn lines will connect to the asterisk server and calls will be farmed out to people in their homes as call centre agents (one incoming line per agent).
The big question is, will this setup work from behind a NAT firewall with one public IP address or will I have to obtain a number of IP address and get rid of my firewall?
Would it make a difference if I used a PC rather than a mac (I want to avoid this if I can)
Media gateways seem hard to come by in Australia (I suspect this will change over the next 12-18 months). What is the best (read cheap) type that a mac user can get their head around and will it work with the Australian PSTN standards.
For 6 incoming lines what broadband speed is optimal?
Are there (NAT) firewall considerations at the remote end?
Or am I on the completely wrong track and i should use a tradional (expensive) pabx?
