In an effort to implement VoIP solution at my HOME, I found that I could use either cisco uBR924 cable modem router or 827-4V ADSL. I came to know that in order to call PSTN numbers around the world, I should use a gateway. Here are my questions:
1) Is there any service provider who provides JUST gateway service to accomplish VoIP.
2) Are there any standalone Cisco products that provides a gateway service. If so, does it interoperates with ADSL and Cable modem.
I am looking for a cost effective gateway product to accomplish connectivity to PSTN to cut international calls telephone cost.
