if you have a spare trunk port and a spare analog port.. the cost is zero... use an analog port for dialtone.. then have the courtsy phone hot d the acod of the new route... really pretty simple.
i use one, the cust does not have to dial 9 and the tfd can be 3 minutes... the caller can redial, some do but not very often.. you do get a code every time a caller gets cut off.. so if i get 3 or 4 codes in a row i disable the trunk.. if your going that way let us know and someone can post the rdb and trunk
