I have a customer that wants to provide analog phone service for various properties they manage. They would use a centralized Call Manager, either BE or CUCM. They have data network connectivity to the buidings that have cat 1 or 3 cable. I want to install VG224s at the locations to provide analog phone service. From other posts, it does not appear that I need DLUs for the VG224s. Is there a limit to how many VG224s I can have on the BE platform? Does each port count as a user against the 500 user limit?
