We are migrating a legacy PBX system to IPT. We had 20 Analog lines from the PSTN going to the PBX sone of which were private lines that would ring on specific individuals desks. We are considering replacing the 20 Analog lines with a T1 PRI from the Telco. The T1 will be terminated on a 2620XM. Our challenge is to have the same scenario in the IPT environment as was in the Legacy environment (private lines via the PBX). Will it be possible to have a specified channel on the T1 line ring on a specific user's IP Phone, thus creating a private line for that user?
