PRI if thats on the table. Easy to debug

PRI also gives you the flexibility to provision just the needed lines. like you could probably take  a 4 lines on your PRI and just use those channels.

Config wise and debug wise PRI is easier. Personal Troubleshooting experience

Hi

PRI if the users are busy enough on the phones to warrant the minimum number of channels you are allowed to order (it varies depending on provider).

BRI if you only need a few channels or PRI is too expensive.

FXO if you absolutely can't use anything else - try seaching the forums for FXO voice quality, FXO disconnect supervision, FXO answer supervision to get a sample of some of the problems you are likely to hit. Even if all goes well, FXOs generally have notably lower voice quality.

Hi

Quite possibly; it depends on your SP's pricing and your usage.

That's why I suggest BRI (2 channels per circuit) rather then FXO; far more reliable and with much better quality.

Thanks much for the input.

With just let's say 10 users and with the ratio 1 line per 3 users, PRI will be a waste of money right?

for a BRI circuit we're looking at about 6 users or so correct?

Hi

It really depends on the user base; that would seem reasonable but if you have heavy phone users you may need more.
