We have a trunk line system in our office, however we would like to add several handheld phones we could walk around with that would function same as our multi-line desk phones do. We would probably use 5-10 additional handheld units.
Thanks,
Ben

The basic difference is that, while a PRI Line carries 30 Channels on a single circuit (one can make 30 simultaneous calls using it), a BRI Line carries 2 Channels on a single circuit. Both are digital lines. You can refer to the following articles to understand further about either of them.
