What are the best configurations & devices for setting up two-way IP
Gateway between NJ and Kolkata (India) so that any authorized person
can route their international call originating from their ordinary
phone (land line or cell) at either country. The objective is to validate
if one can make international calls using IP Telephony Technology --
at the cost of local calls. We can invest in the high speed lines (tell
us what type is available at Kolkata, India and at what cost --
Onetime, monthly, speed...) and required IP Telephony gateway
equipments (and all associated costs) that will provide us carrier
grade voice quality. We plan to start small say 2 lines and then
upgrade to 8 lines in 12 months.
