VoIP bandwidth question

As much as i can't give you an exact answer on the bandwidth i can tell you it's very low. We are using cisco 1700 routers for our VOIP and they really work great and use very little bandwidth. When you configure the router you'll be able to tell it how much it can use and what it actually needs is very little and the connections are always good. At our main office we have a T-1 which we use for internet, VOIP, etc and at the remote office we only have DSL which is also used for everything including VOIP and it hasn't let me down yet.

Info on the subject.

I would contact Cisco and have them design your lan. They will provide you with a complete solution including voip intregrated hardware and software.

If you don't do it right you will not be pleased with the results. Garbled conversations are not easy to deal with.

Total voip (if all users are talking via the internet would be 1,560,000 bits [basically a DS1]), if between each other 768,000 ][]1/2 DS1], this only happens usually once a quarter and most go for the intranet (link between the 2 sites). What about file size that will be dragged accross the network? Large ones > 1 meg and accessed many times will require more bandwidth, could try a single DS1 to link sites together and if customers complain of slowness add another.

Bottom line is there is no definitive equation to calculate bandwidth required, depends on the company and users where you will need to expand or contract the pipe. All companies have the web surfers on the clock to some extent.
