I have a client who uses 6000 speed dial numbers. They are looking at converting to an IP Office. I see where the directory limit is 10K using LDAP or HTTP but I am having difficulties finding documentation on how to actually create and program the list into the system. Is the actual directory held/managed via an external source such as the same PC used for VM Pro? I am wondering how time-intensive it is to build originally and subsequently manage. Any direction appreciated. Thank you in advance.
