we have many vg224 gateways. There are problems with freeze the phones and faxes from time to time. I tried to change the IOS but it wasn't helpful. When the phone/port freeze i have to restart VG224 and all functions are correct for some time.
What do you mean by 'Freeze'? We've been having issues with our VG224 for a while now where the ports (usually individual ports) stop working. A 'no mgcp', 'mgcp' usually starts things up again. I think we've done a shut, no shut on the port and that fixes things for that port.
We've also tried upgrading IOS revisions (got another one to try on Friday) to try and solve the issue.
I talked to a TAC Engineer today. He is trying to reproduce it in the lab. He mentioned that there was something similar that resolved in IOS version 12.4.6. I ended up loading 12.4(6).T2 on a couple boxes and so far so good. However, like you mentioned it has only been up for a week and a half and that is not long enough to determine if the problem is relsolved. I will let you know if I find out anything else.

The short answer is that you don't.... That isn't entirely true while at
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
