I have been given the task of setting up a telephone network in US and India. When customers call the US location, the calls should route to India (using VoIP) and handle there. The Indian location should be able to call Us numbers using the Voip to save money. The solution should be flexible enough to support initial of 5 simultaneous calls with the option to expand to 20+ within a year. > > 1) Can anyone direct me what is the minimum hardware needed. (or most inexpensive solution)
the minimum hardware required for any * installation is going to be directly proportional to your performance expections. the scenario you are describing above sounds like you are using this for a mission critical application and any hardware decisions should be treated as such (read-buy the most rock solid box that your budget allows) > > 2) If we use dedicated T1 in both location, will the voice quality be good enough? > Dedicated to what? Bandwidth? PSTN connectivity? VoIP is and will always be as stable as the IP network it is running on. If you try to run dozens of customer calls over a 256k DSL across the public internet to your Indian location where there is a 128k BRI your customers will probably not call you back. If you are putting a T-1 of bandwidth in at each location and have consistent ping times (the most rudimentary IP packet testing) you could experiment with sending some test calls between a couple of * boxes and make the determination that the voice quality is sufficient to subject your customers to. > 3) Can we use Vonage or a company like that for the voip to save on T1 cost? Sure you can. But again, if this system is mission critical to your company then buy a PRI/T-1 and get some DID's. The headaches you get working to keep your ISVP connections up outweigh the 20% extra operational expense that leased lines will give you. Finally, you freely admit that you are new to voip/*. take care in jumping headlong into this too quickly. most of us have spent significant hours in our 'labs' trying to figure out this stuff. the wiki has a great listing of consultants just waiting to assist you with projects like this (for the right price).
