In the past, I've always installed PRI software from the start (e.g. new installation, upgrade to T1). Now, I have a client that has basic T1 service wanting to upgrade to PRI. Carrier is going to "bump-up" their service to PRI on a specific date/time.

My question is: If I do not have the PRI software installed as of the cut-over, will the system still function as it has been? Does upgrading to PRI service from the carrier change anything BEFORE the software is installed? Problem is, I may not be able to install the software at the exact time of the cut-over and I do not want the client's service to be disrupted.
