Cheap Call Centre Solution For Inbound Calls AnyOne?

I'm looking for some sort of a cheap small call center solution, mainly for inbound calls.

Some features I need are like:
- few different numbers in different countries
- logging of inbound calls
- call waiting
- sort of a computer voice
...


Do you guys (and galz) got any idea how to do this cheaply?

So far I've been using OpenVBX/Twilio and it is working fine for me. You can record the welcoming message (or use the text-2-speech option), set the option 1 for sells, 2 for tech, ... forward to available agent, etc...

You might need to get a little bit programming done to the platform since it's not perfect, but works fine and it's open source.
I pay between $0.01 - $0.05 per min. depending if it's incoming or outgoing and the destination to call.

Someone me that safesoftsolutions(dot)com is good but I have not tried they platform yet.

I've looked at whole bunch of them to switch from current that's not good, and going to either telax, 3c logic or incontact

Just spring for RingCentral....Their quality is unmatched and they are incredibly reliable
