Do you have multiple phones connected to some/many of the Ports?? If so
you may be hitting this restriction;
Connecting Too Many Phones to the VG248
The VG248 has a maximum ringer equivalency number (REN) load of three (3) per line (using a shared directory number), and only two devices can be off-hook at any one time. Because some devices might have a REN load greater than one (1), you cannot necessarily connect three devices to the chain. If these requirements are ignored, you might experience reduced quality on these analog phones, including:
•Difficulty hearing caller—Users have too many phones off-hook. Do not have more than two phones per line off-hook simultaneously.
•Dialing or caller ID on call waiting are not working properly—Users have too many phones off-hook. Do not have more than two phones per line off-hook simultaneously.
•Phones not ringing properly or at all—REN load has been exceeded. Do not exceed the REN of three (3) per line.
•Phone power supplies (-48v and -96v) fail—REN load has been exceeded. Do not exceed the REN of three (3) per line.

the same time it kind of is, but for the most part you don't configure
the softkeys. You enable or disable them via TCL. Here is the long
answer. Be sure to read the whole thing or e...
